Is it possible to default to mksh or any other shell, while automatically falling to sh when that shell port isn't available on my system, without needing to go into single user mode? The chsh (chpass) command only offers one shell setting here. This usually isn't an issue, but it becomes a...

As this question is regarding a package in the base system, this seemed like the best place to ask. If not, just recomend a new place to ask and I'll move it there. I'm attempting to migrate from ZSH to CSH and the configuration is proving to be a bit difficult. In ZSH, I have these lines...

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...

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, 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...

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...
