shell

Tell about your favorite FreeBSD shell. What opportunities are you most interested in? How many lines does your shell configuration take? This question is because I saw monstrously complex .shrc in someone's dotfiles on github. Does anyone use csh in FreeBSD 14 for a non-privileged user or even...

I would like to call a command inside a jail using jexec while setting environment variables for that particular call. In a shell inside the jail I would call: KEYCLOAK_ADMIN=admin KEYCLOAK_ADMIN_PASSWORD=admin ./kc.sh show-config How can I trigger this call outside of the jail? I tried...

Hello, Is it possible to display a variable on STDOUT and keep the hand in order to use/edit it ? I've tried to remove the carriage return or newline with tr , or changing IFS but that didn't work. So after few hours on this I just wonder if it is possible, if yes what command/tool can do...

Hello, What would be the port you would recommend to someone who wants to try Kornshell? I thought it would be wise to ask directly to those who have already installed some of the ports in the repository since there are many of them: ast-ksh-20141224_1................KornShell 93...

Hello all, With Git, you basically have 3 choices for a server: Git protocol (similar to svnserve but with no authentication or encryption) HTTP(s)/CGI/smart/dumb/webdav SSH Personally I am not entirely happy with any of them (Git protocol has no authentication, HTTP(s) needs central...

Hello, I'm experimenting with data filtering use some of console programs and found weird behaviour with piping STDOUT of GNU grep to /dev/null. File test is 10Gb of data (apache log). $ /usr/bin/time -h ggrep 'GET' test > /dev/null 0,00s real 0,00s user 0,00s sys It seems...

HI, FreeBSD Gurus ! Please suggest me tool/sys utility/script that : - constantly running in a background under root privilege; - saving local-attached terminal (monitor on server's VGA output, no any GUI used) screenshot to destination folder; - periodically (hourly or daily, or certain day of...

I know that for a long time, the standard advice for the default root shell was "don't change it" (which I learned many years ago when I got myself into a mess after having changed it 😛). Is that still the case? I seem to remember that the issue was that if you changed it to, say...

Hello, is there any way to prevent the system from printing to vt? It's quite annoying when I edit files in vi or ed and the system suddenly tells me that a USB device has disconnected, overwriting the interactive shell. The same goes for services like samba_service. Can anyone tell me how to...

This has to have a simple answer somewhere but cannot seem to find it for FreeBSD specifically. Given this input: DT='2022.02.30' I want to determine that this date is invalid. I first turned to the date utility: echo $DT ; date -j -f '%Y.%m.%d' $DT ; echo $? 2022.02.30 Wed Mar 2 15:56:22...

I have been writing a bunch of shell scripts that essentially wrap existing commands so I don't need to remember the intricate details for most of what I want to do. I have a shell script that essentially builds parameters to call another executable. Some of the arguments should not be...

Hello, Please, give me an advice, how to set the / for my script, to it accidentally no to "bound out" the borders of my "program" that consist of a lot of a sh scripts. Should I choose the "chroot" for this? Peace

Hello, I've entered man read from sh shell and saw pushd and popd inside but there is no such builtin in sh, it's bash' builtin, Which command should I use for referencing sh builtins?

Hello, I'm trying to understand the process of starting scripts and understand shell itself. I would like to ask: what is $rc_fast_and_loose? in if [ -n "$rc_fast_and_loose" ]; then set $_arg; . $_file what is -n here? is it True if the length of "STRING" is non-zero. ? and what...

I did a find / -name 'XXX' and the output is insane. It lists every file and the list never ends (I had to Ctrl-C to stop it). How can I view the results meaningfully? For example, I'd like to limit to the result to appear only for, say the top-level (or top 2nd or 3rd level) directories only...

I think I asked this question sometime ago, but I can't find the answer when searching for it. Anyway... First, I think I know the difference for startup shell scripts located in /etc/rc.d and /usr/local/etc/rc.d. The former is for system scripts while the latter is for user-installed scripts...
