Hi there. I'm sorry if this was asked before.

From my digital camera I got files like that:
img_6775.jpg img_7042.jpg img_7051.jpg img_7066.jpg img_7037.jpg etc. ...

I want to rename like 01.jpg; 02.jpg; 04.jpg; 05.jpg; etc. ...

I installed mmv but still cannot figured out how to do this.
Can give me some advices?

thanks
 
If you're fond of GUI, install sysutils/pyrenamer.
It has some dependencies but is very handy here.
 
Code: 
#/bin/sh
for i in `ls *.jpg`; do
  mv $i $(echo $i | sed 's/^img_//')
done
exit 0

This sh script should do it

EDIT, ah no, soory, this will only remove img_
 
Code: 
#!/bin/sh
j=0
for i in `ls *.jpg`; do
  j=`expr $(echo $j) + 1`
  if [ $j -lt 10 ]; then
    mv "$i" "[color="Red"]0[/color]0${j}.jpg"
  [color="Red"]elif [ $j -lt 100 ]; then
    mv "$i" "0${j}.jpg"[/color]
  else
    mv "$i" "${j}.jpg"
  fi
done
exit 0

ok here it is ;)

This will output file names with 3 digits.
If you want only 2 digits, remove text in red


I suggest you test it first in temp on some files ;)
and only then try on your collection (just to make 100% sure)

here what I done
I create a file: rename.sh, copy your script inside, make the file executable and copy in the folder where my files are
Code: 
> ls
img_6775.jpg	img_7048.jpg	img_7056.jpg
img_7037.jpg	img_7050.jpg	img_7066.jpg	
img_7038.jpg	img_7051.jpg	img_7071.jpg
rename.sh
> ./rename.sh 
j=0: Command not found.
for: Command not found.
do: Command not found.
Illegal variable name.
j=: Command not found.
i: Undefined variable.

do I need bash, or something?
 
That's because it should be
Code: 
#[b][u]![/u][/b]/bin/sh
instead of
Code: 
#/bin/sh

You don't need bash. This line ensures the script is ran by the Bourne shell.
 
Try this script:

Code: 
#! /bin/sh

c=0

for i in `ls img_*.jpg`; do

        c=`expr $c + 1`
        o=`printf "%02d.jpg" $c`

        echo "${i} -> ${o}"

        mv "${i}" "${o}"
done
 
I would suggest adding some form of checking to determine if the file exists before moving. Otherwise you might overwrite a picture.

Code: 
for I in images/*
do
  COUNT=$(( ${COUNT} +1 ))
  if [ ! -f $( printf "%02d" ${COUNT}).jpg ];
  do 
    mv ${I} $( printf "%02d" ${COUNT} ).jpg
  done
done
 
the easy way.

This is bash tho ...

Code: 
[lbl@atom0 ~/test]$ ls
IMG_1127.JPG	IMG_1130.JPG	IMG_1133.JPG	IMG_1136.JPG	IMG_1139.JPG	IMG_1142.JPG	IMG_1145.JPG	IMG_1148.JPG
IMG_1128.JPG	IMG_1131.JPG	IMG_1134.JPG	IMG_1137.JPG	IMG_1140.JPG	IMG_1143.JPG	IMG_1146.JPG	IMG_1149.JPG
IMG_1129.JPG	IMG_1132.JPG	IMG_1135.JPG	IMG_1138.JPG	IMG_1141.JPG	IMG_1144.JPG	IMG_1147.JPG	IMG_1150.JPG
[lbl@atom0 ~/test]$ n=0 ; ls | while read f ; do n=`expr $n + 1` ; mv $f $n.jpg ; done
[lbl@atom0 ~/test]$ ls
1.jpg	11.jpg	13.jpg	15.jpg	17.jpg	19.jpg	20.jpg	22.jpg	24.jpg	4.jpg	6.jpg	8.jpg
10.jpg	12.jpg	14.jpg	16.jpg	18.jpg	2.jpg	21.jpg	23.jpg	3.jpg	5.jpg	7.jpg	9.jpg
[lbl@atom0 ~/test]$

For example, to rename all files matching C<*.bak> to strip the extension, you might use
Code: 
        rename 's/\.bak$//' *.bak
To translate uppercase names to lower, you'd use
Code: 
        rename 'y/A-Z/a-z/' *
 
Here is my 50 cents on this, i have choosen a script i understand and use it every 15 minutes to fetch the scans from my epson multifunctional, becease it just is not reliable, it looses connection every now and then, so i just let FreeBSD take care of this thing.

This is how my batch script looks like:

Code: 
#!/bin/sh

## Copy the scans every 30 minutes from the printer, so we don't
## have to struggle to get the scans anymore
#
umount -f /mnt/EPSON

mount_smbfs -N //Epson00595a/MEMORYCARD/EPSCAN /mnt/EPSON

mv /mnt/EPSON/EPSCAN/001/* /encrypt_a/Special/Scans

cd /encrypt_a/Special/Scans

## Rename the Epson files to scans witch date and follow-up number
##
j=0
datum=`date '+%d-%m-%Y_%H-%M'`

for i in `ls EPSON*.PDF`; do
  j=`expr $(echo $j) + 1`
  if [ $j -lt 10 ]; then
    mv "$i" "scan_${datum}-00${j}.pdf"
  elif [ $j -lt 100 ]; then
    mv "$i" "scan_${datum}-0${j}.pdf"
  else
    mv "$i" "scan_${datum}-${j}.pdf"
  fi
done

j=0
datum=`date '+%d-%m-%Y_%H-%M'`

for i in `ls EPSON*.JPG`; do
  j=`expr $(echo $j) + 1`
  if [ $j -lt 10 ]; then
    mv "$i" "scan_${datum}-00${j}.jpg"
  elif [ $j -lt 100 ]; then
    mv "$i" "scan_${datum}-0${j}.jpg"
  else
    mv "$i" "scan_${datum}-${j}.jpg"
  fi
done

j=0
datum=`date '+%d-%m-%Y_%H-%M'`

for i in `ls EPSON*.jpg`; do
  j=`expr $(echo $j) + 1`
  if [ $j -lt 10 ]; then
    mv "$i" "scan_${datum}-00${j}.jpg"
  elif [ $j -lt 100 ]; then
    mv "$i" "scan_${datum}-0${j}.jpg"
  else
    mv "$i" "scan_${datum}-${j}.jpg"
  fi
done

umount -f /mnt/EPSON

exit 0

The scanner only produces PDF, JPG and jpg.

I almost forgot: THANKYOU!
