multishell user profile
Hi: I need to create a user profile that works in different shells, particularly bash, csh and ksh. It seems that these does not read the same files and/or in the same order. So, how do I configure the shell profiles without configuring each shell separately? Also, I can't find information if they use the same syntax, or what syntax they share so I can stick to that. Does POSIX specify any of this?

Well, each shell reads different files for environment variables, etc. So just have those files in ~/ and install the shells, then invoke them as you wish. -- Best regards, Odhiambo WASHINGTON, Nairobi,KE +254733744121/+254722743223 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ If you have nothing good to say about someone, just shut up!. -- Lucky Dube ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

See login.conf(5) -- you can set environment variables for all users independent of what shell they use.

It seems that these does not read the same files and/or in the same order. So, how do I configure the shell profiles without configuring each shell separately? You can't - at least not very easily. Of course, you can do as few shell initialisations per se if you use things like login.conf to set environment variables instead of manually setting them in the shell config. The main problem is: The shells you mentioned to use different formats for their configuration. For example, while you can use set promptchars = %# set prompt = %...@%m:%~%# for your csh, you have to use a different syntax in bash. The same goes for aliases. A chance to partially bypass this is to put as many customization as possible into script-defined commands that you place in ~/bin (and add this to $PATH). Of course, this approach doesn't solve all imaginable problems. As for reading order of configuration files, refer to the manpages: man csh man bash man ksh You will see which files are accessed, and in which order, and where you can put centrally managed profiles as well as user- specific profiles. Also, I can't find information if they use the same syntax, or what syntax they share so I can stick to that. They don't use the same syntax. Maybe you'll find a good comparison chart of shell syntax and capabilities. As stupid as it may sound, you'll find some information here: http://en.wikipedia.org/wiki/Comparison_of_command_shells http://en.wikipedia.org/wiki/Unix_shell -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ... ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

The two things that bite me the most often when switching shells are
environment variables and aliases. I keep most of my environment stuff
in a single file ($HOME/.envrc) with entries like this:
# Local time for RCS date information
RCSINIT -zLT
# Default file browser.
PAGER less
A small perl script converts this into sh- or csh-style commands, so I
can just source the appropriate file from .bashrc or .tcshrc or whatever:
me% cat ~/.envrc.sh
# Local time for RCS date information
RCSINIT=-zLT; export RCSINIT
# Default file browser.
PAGER=less; export PAGER
me% cat ~/.envrc.csh
# Local time for RCS date information
setenv RCSINIT -zLT
# Default file browser.
setenv PAGER less
Aliases are annoying because the syntax is inconsistent, so I only use
those for inside-the-shell stuff like job control. Small ~/bin scripts
handle things like using dir instead of ls -lF:
#!/bin/sh
#dir: long directory listing; skip colors if running script/saveon.
case $SAVEON in
) opt='--color=auto' ;;
*) opt='' ;;
esac
unset BLOCK_SIZE# throws off the results for GNU ls.
exec /usr/local/bin/ls -lF $opt ${1+$@}
exit 1
Put the invariant stuff in the system startup files. Something like
this in /etc/profile would handle a general bash/ksh/sh environment:
test -f $HOME/.envrc.sh . $HOME/.envrc.sh
