Useful scripts

graudeejs said:
$ echo $PATH | tr ':' ' ' | xargs -n 1 echo
You can probably write this even shorter

Here's better one
$ echo $PATH | awk 'BEGIN {RS=":"}; {print $0}'

this one will respect spaces in directories
 
I frequently use this script when preparing FreeBSD-box since REL-4

Code:
.type catch
catch is a function
catch ()
{
    [ "$1" ] && $PAGER `which $*`
}
.
.catch mona
#!/bin/sh

Synopsys:
  mount/unmount any ufs and/or dos filesystems

Changelog:
  version 1.0.4d, last update: 2008.11.5
    (small fix add freebsd release 8 & 9)
  version 1.0.5, last update: 2009.01.03
    (allow more than 1 filter, remaining args
     will be treated as filters. examples added)
  version 1.0.5a, last update: 2010.01.01
    (update: FreeBSD 8+ allows more slices, upto silce-z)

Usage:
  [sh] ${0##*/} mount_arg filesystem_arg filter_args...

Where:
  mount_arg is either mount (read-only, read-write) or unmount
    valid choices are: -m, -mr, -mw and -u
    - preceding dash (-) IS required

  valid choices for filesystem_arg are:
    u, ufs, f, fat, n, nt, ntfs, d, dos, and all
    - could be in any (upper/lower/mixed) case,
    - preceding dash is allowed but not required
    - if not supplied, default to UFS

Examples:
  [sh] ${0##*/} -m -a
  mount all partitions, ufs and dos (fat/ntfs)

  [sh] ${0##*/} -u
  unmount ufs only (dos partition will NOT be unmounted)

  [sh] ${0##*/} -mw ufs ad4s2[a-e] ad8s?[a-e]
  mount read-write ufs disk4 slice 2 and disk8 (any slices)
  partition a to e (usually root, var and usr/local)

Notes:
  when filter_args is given, then the preceding 2 arguments
  (mount and filesystem) must also be supplied

  default mount (-m) is read-only
  root dir will be under $ROOT/BSD or $ROOT/DOS

I had enough of updating vim plugins and help tags manually, so I wrote 2 scripts:

This script updates my plugins by downloading tar.gz from github:
update_plugins.sh modified and renamed: https://github.com/graudeejs/dot.vim/blob/master/github_plugin_update.sh

And this script updates all help tags for all doc directories in ~/.vim/
https://github.com/graudeejs/dot.vim/blob/master/update_tags.sh


EDIT, I updated scripts.... so now there's also Makefile:

enjoy!

Updated and renamed script to update_plugin
Now it also supports gitorious.
 
System updating script

I wrote a small script for my own use for making the daily update checking process (using portmaster) on my boxes easier. It can also check jails for updates using ezjail.
The script has two modes of operation: ports (portsnap -> portmaster) and source (csup).

I am pretty much a bash newbie, but I hope that someone will find it useful anyway. :)

Your script looks good. In fact it looks like posix so you could use #!/bin/sh. As a pet peeve of mine I prefer any external applications to use env() for portability (i.e. #!/usr/bin/env bash) This would be the same for ruby, perl etc. Though your script is FreeBSD specific I guess it really doesn't matter.

If you'd like to transverse the jails running you can use jls() and create a list from there to run your commands with jexec(). Here is an example to get the current running jails for use with jexec:

Code:
jls | tail -n +2 | awk '{print $1}'

If you need the names you can change the awk print statement to $3 and ip addresses are $2.

Here is an old script I used for jails to generate a report on out of date packages with pkg_version() and/or portversion if installed. Maybe you might find it useful for your jails supervision scripts as it has no actual dependencies on ports.

I'm using x11/slim as my login manager.

Today I had this idea:
Why not to save last used WM and use that as default next time I log in

Slim doesn't support this. But it doesn't have to. Everything you need is to adjust you ~/.xinitrc

The magic code snippet
Code:
DEFAULT_WM="fvwm"
if [ "$1" ]; then
    export WM="$1"
else
    export WM="$DEFAULT_WM"
    [ -f "$HOME/.last_wm" ] && WM="`cat "$HOME/.last_wm"`"
fi

echo "$WM" > "$HOME/.last_wm"

# now exec your WM

Here's my full ~/.xinitrc

change national characters to ASCII equivalents

If You move files from one filesystem to another, especially to FAT32/NTFS and then back to UNIX filesystems, then You probably had encoding issues because of 'national' characters, which means unable to locate the file while You know its there or unable to remove it.

The solution to this is to rename/keep all files in ASCII names, so wherever they go, they are 'safe'.

Its 'configurable' by changing the ASCII='...' line, the default is:
ASCII="echo \"${FILE}\" ${TR} ${Tr} ${Or} ${OdQ}"

Which also translates various variants of '-' to ASCII one, ™ to TM, ® to R and removes ! character.

It also can be 'configured' to remove brackets, both (/) and [/] and {/}.

Below is the script that I use to make such ASCII 'normalizations', and an example.

Good morning,

I don't like your solution, as it creates more problems than it solves.

Here some thoughts about the way you handle this issue:
  • The solution doesn't solve the problem you announce it solved (FAT32/NTFS -> UNIX filesystem file moves).
  • This method shows disdain to your international users: their glyphs are't allowed on your system.
  • The script doesn't care about proper transliteration. For example, ß should be replaced by ss (like s0=" | tr 'ß' 'ss' ").
  • There is a vocabulary issue, letting know you've some progress to do (or you don't really care) about l10n. For example, a language doesn't match a country, so “national characters” doesn't mean anything. You even need non ASCII characters in English too. Here two filenames I've found Wikimedia Commons' pictures: Production drawing Pink Panther In “Olym-Pinks”, 1980.jpg and Everybody Loves Eric Raymond 2006-01-11, The GPL3 according to….jpg.
  • And the killer argument: there is an encoding well supported by your UNIX filesystems and your OS: this is called UTF-8.
  • If you use UTF-8, you can mount a NTFS filesystem (which internally stores filenames in UTF-16) in UTF-8, and so have directly compatible filenames.

Now, your method would be useful in this case to convert FAT32 filenames.

Code:
#!/bin/sh
ENCODING_SOURCE=iso-8859-1
#To import Windows FAT32, use instead: ENCODING_SOURCE=cp1252
ENCODING_TARGET=utf-8

[ ${#} -eq 0 ] && {
  echo "usage: ${0##*/} FILE|DIRECTORY"
  exit 0
}
for FILE in "${@}"
do
  NEWNAME = `iconv "${FILE} -s -c -f ${ENCODING_SOURCE} -t ${ENCODING_TARGET}//TRANSLIT`
  if [ -z "${NEWNAME}" ]
  then
    echo "Can't rename ${FILE}"
  else
    mv "${FILE}" "${NEWNAME}"
  fi
done

It could also be used to keep characters your encoding should support, like é or ß with ENCODING_SOURCE=cp1252 and ENCODING_TARGET=cp437 (if you use cons25 encoding).

iconv with use transliteration to convert any character not existing in target encoding according state of art admitted rules:
Code:
A origem da povoação de Pereira parece estar ligada às vic….pdf (UTF-8, original)
A origem da povoaâ–’~ao de Pereira parece estar ligada â–’s vic....pdf (cp437, for cons25)
A origem da povoaç~ao de Pereira parece estar ligada às vic....pdf (converted back in UTF-8, this bulletin board encoding)

Note: There are two ports, converters/libiconv and converters/iconv. You probably already have libiconv installed, and probably with this option enabled ([X] EXTRA_ENCODINGS). If you have to install one and choose converter/iconv instead converter/libiconv, don't forget to install also converter/iconv-extra port and to note your binary will be "biconv" to avoid conflicts.

Thank You for Your arguments, I will try to address them below.

I don't like your solution, as it creates more problems than it solves.
It solves problems for me, but I do not agree that this is the best way to solve others' people encoding problems.

[*] The solution doesn't solve the problem you announce it solved (FAT32/NTFS -> UNIX filesystem file moves).
I use it to rename files that are still 'valid', ofter when copying from FAT32/NTFS with different encoding then neede mounted, files will copy with 'bad' characters. I was thinking generally about issues with transferring files between FAT/NTFS and UNIX filesystems, not directly about FAT/NTFS -> UNIX migration.

This method shows disdain to your international users: their glyphs are't allowed on your system.
I personally disdain MY national language/characters and think that they are harm/dangerous in filenames and also change them. I haven't thought about changing OTHER people filenames with that, only mine.

The script doesn't care about proper transliteration. For example, ß should be replaced by ss (like s0=" | tr 'ß' 'ss' ").
I have read about 'ß' in Wikipedia, but, for simplicity I used only one 's', the script is editable and You can make it to change 'ß' to 'ss' instead of 's'. By definition/language rules, 'ß' is a 'ss' representation in one character, but I do not care (yes, its my ignorance) how *strong* is this 's', its still an 's'.

By the way, to make it work, You will have to change it like that (tr will not work):
Code:
[color="Red"]-s0=" | tr 'ß' 'ss' "[/color]
[color="Lime"]+s0=" | sed s/'ß'/'ss'/g "[/color]

[*] There is a vocabulary issue, letting know you've some progress to do (or you don't really care) about l10n. For example, a language doesn't match a country, so “national characters” doesn't mean anything. You even need non ASCII characters in English too.
My knowledge about l10n (and i18n) is limited, I did not dig that topic, I just wanted to solve the problem, and as tiem has passed I first created that script only with characters from my native language, then added all other possible characters, that will make my life easier.

And the killer argument: there is an encoding well supported by your UNIX filesystems and your OS: this is called UTF-8.
Great, but does FreeBSD console is fully UTF-8? Nope. Is everything in computing UTF-8 compatible? Nope. Until then I will translate 'national' [*] characters to english harmless ones.

[*] yes I remember that You mentioned that this naming convention is not valid, but its what best describes that issue for me

Now, your method would be useful in this case to convert FAT32 filenames.

Code:
#!/bin/sh
ENCODING_SOURCE=iso-8859-1
#To import Windows FAT32, use instead: ENCODING_SOURCE=cp1252
ENCODING_TARGET=utf-8

[ ${#} -eq 0 ] && {
  echo "usage: ${0##*/} FILE|DIRECTORY"
  exit 0
}
for FILE in "${@}"
do
  NEWNAME = `iconv "${FILE} -s -c -f ${ENCODING_SOURCE} -t ${ENCODING_TARGET}//TRANSLIT`
  if [ -z "${NEWNAME}" ]
  then
    echo "Can't rename ${FILE}"
  else
    mv "${FILE}" "${NEWNAME}"
  fi
done
I will look into that, thanks.

It could also be used to keep characters your encoding should support.
Maybe it will for encodings that I use, but the I would take that drive to the system that does not support these characters and the problem begins again.

Will it rename the filenames as my script does (removing all national characters?), if yes, then maybe my scripts is useless and there is far better tool to do that?

Regards,
vermaden
 
@Dereckson

I just tried using iconv, it translates with 'additional characters, which is unacceptable:

Code:
% echo ẃŵẅÿýỳŷžżź | iconv -c -f utf-8 -t iso-8859-1//TRANSLIT 
�w^w"w��`y^yzz�z

While my toascii.sh script does the job and translates 'ẃŵẅÿýỳŷžżź' into 'wwwyyyyzzz'.

Here is the latest version, with more characters:

toascii.sh
Code:
#! /bin/sh

[ ${#} -eq 0 ] && {
  echo "usage: ${0##*/} FILE|DIRECTORY"
  exit 0
}

Perhaps consider a script in Python? Hooking in the file renaming is easy enough, here is the character normalization using the "normal form KD" decomposition/composition:

Code:
import unicodedata

def normalize(string):
    return unicodedata.normalize('NFKD', input_string).encode('ascii', 'ignore')

print(normalize("ẃŵẅÿýỳŷžżź"))

Produces:
Code:
wwwyyyyzzz

There is a little more to it than this; UTF-8 encoded strings read from the console or file system must be decoded as Unicode bytestrings, so the code will grow by a few more characters here and there. I'm posting this to show the unicodedata module in Python has done a lot of legwork needed for tasks like this. I guess I'll need to round it out and provide a complete script to be in keeping with this thread. Stay tuned, will be back.
 
@mwatkins

Thanks for that great tip, I am gonna dig into that python normalization right away! ;)

EDIT:

I tried something like that:

Code:
#! /usr/bin/env python
# -*- coding: utf-8 -*

import unicodedata

def normalize(input_string):
    return unicodedata.normalize('NFKD', input_string).encode('ascii', 'ignore')

print normalize("àÀáÁâÂäÄăĂãÃåÅɐⱯąĄāĀăĂǟǞḃḂçÇćĆčČċĊďĎðÐḑḐďĎḋḊđĐðÐéÉèÈêÊëËęĘěĚɛƐəƏēĒĕĔėĖʒƷǯǮḟḞƒƑǵǴģĢǧǦĝĜğĞġĠǥǤĥĤħĦíÍîÎïÏìÌĩĨīĪĭĬįĮıIĵĴĸḱḰķĶǩǨĺĹľĽłŁŀĿļĻṁṀñÑňŇńŃŋŊņŅʼnôÔöÖőŐòÒøØóÓõÕōŌŏŎøØǿǾṗṖŕŔřŘŗŖŝŜşŞšŠśŚṡṠťŤţŢŧŦþÞùÙúÚûÛüÜůŮűŰũŨūŪŭŬųŲẁẀẃẂŵŴẅẄÿŸýÝỳỲŷŶžŽżŻźŹæÆǽǼdžDŽdzDZœŒßβΒſß™®![](){}")

TypeError: must be unicode, not str
 
You have to tell python that the string literal is unicode:
Code:
    print normalize(u"àÀáÁâÂäÄă...

On python3 there is no such problem because all strings are unicode. Another reason to prefer python 3 over 2 :)
 
Simple one-liner for PKGNG. This prints out installed packages sorted in order of their installation times. Output is installation time formatted with current locale and the package name.

$ pkg query "%t %n-%v" | sort -n -k1 | while read timestamp pkgname; do echo "$(date -r $timestamp) $pkgname"; done


This works only in bourne type shells.
 
Code:
#!/bin/sh

if [ $# -eq 1 ] && [ $1 = "cron" ]
    then /bin/sleep $(/usr/bin/jot -r 1 0 3600)

/usr/sbin/portsnap fetch update || exit 1

echo "  ~  6  ~   What is available in the repositories..."
/usr/sbin/pkg update || exit 1
/usr/sbin/pkg upgrade -Lqn || exit 1

    then usedate=$weekago
    else usedate=$lastpkg

Hereby a small update of DutchDaemon's script. This one uses the new pkg(8) tools.
 
When it comes to programming/scripting I´m a pretty newbie. But I try ;)
Here is a script that I´m using occasionally:

Code:
#!/bin/sh -e

# mfetch - a wrapper to fetch(1)
# it mimics wget --input-file behaviour
# argument $1: inputlist
# optional argument $2: directory

unset PATH

# Handling traps
trap 'echo "Aborting on signal." >&2; exit 1;' INT TERM

# Checking arguments
[ $# -lt 1 ] && { echo "Usage: ${0##*/} inputlist [directory]" >&2; exit 1; }

# Checking / Creating directories as needed
[ ! -d $2 ] && /bin/mkdir -p $2

# Feed fetch with URLs from inputlist
while read i; do
    /usr/bin/fetch -q -o ${2:-./} $i
done <$1

exit 0
 
Hi,
here is a nice script to show the temperature of all attached hard disks

30mamqa.png

[1]

It currently works with ata disks.
I have tried to include disks connected to a ciss raid controller, but I am not sure if it works as I do not have one. Could anyone with a ciss controller please check this out and give some feedback.

The source of the script is here
https://github.com/lockdoc/hddtemp/blob/master/hddtemp.sh

It requires root privileges and smartmontools to be installed.

[1] My SSD does not report the proper temperature, that's why it always displays 128
 
The following script disables the fan if the temp is lower than 45 and then enables it again at 55.

I know this isn't a brilliant idea but for some reason my Thinkpad x61 keeps its fan running trying to reach a very low temperature. It becomes quite cold for my wrist and quite uncomfortable for my lap ;)

This will only work when using the acpi_ibm module.

Code:
#!/bin/sh

disable_fan()
{
  echo "disable"
  sysctl dev.acpi_ibm.0.fan=0
}

enable_fan()
{
  echo "enable"
  sysctl dev.acpi_ibm.0.fan=1
}

try_disable_fan()
{
  if [ `sysctl -n dev.acpi_ibm.0.fan` = 1 ]; then
    disable_fan
  fi
}

try_enable_fan()
{
  if [ `sysctl -n dev.acpi_ibm.0.fan` = 0 ]; then
    enable_fan
  fi
}

if [ `id -u` != 0 ]; then
  echo "Error: Must be root"
  exit 1
fi

while [ true ]; do

  HIGHEST_TEMP=0
  TEMPERATURES=`sysctl -n dev.acpi_ibm.0.thermal`

  for TEMP in $TEMPERATURES; do
    if [ $TEMP -gt $HIGHEST_TEMP ]; then
      HIGHEST_TEMP=$TEMP
    fi
  done

  if [ $HIGHEST_TEMP -gt 55 ]; then
    try_enable_fan
  elif [ $HIGHEST_TEMP -lt 45 ]; then
    try_disable_fan
  fi

  sleep 5

done
