Cross-shell environment variables
Dear group,
Is there a way to set a certain environmental ($ENV) variable so that no matter what shell is started, by no matter which user, the variable is present.
More specifically, I want to set $ENV{'PERL5LIB'} to point to my program directory so that no matter where my programs are started from, no matter which user (including nobody and root), the proper directory will be included in @INC.
...but I'm getting ahead of myself. Any help is appreciated.
Thanks,
- Tonyboy

...but won't this simply add the PERL5LIB variable to the bash shell users? tcsh, csh and sh shell users don't source the /etc/profile file, as far as I know.
As far as i know, for sh users, they are using /etc/profile.
For csh,tcsh users, they are using /etc/cshrc.login
If you have both, then you should edit both files.

What about jobs run by cron? What about scripts run by Apache? Do these files get sourced when the shells are started by other programs?
> What about jobs run by cron?
cron uses sh by default, so /etc/profile matches.
If the user uses another shell in her/his crontab, they need to source the appropriate scripts, but AFAIK the cannot cross the limits set by the parent shell (never checked it).
> What about scripts run by Apache?
Apache uses its own user (www, nobody), usually. So the same applies as for cron.

Depends on the shell.
But i.g. you cannot cross the limits set by the parent.

set PERL5LIB="value"
export PERL5LIB
or if your distribution supports setenv, use
setenv PERL5LIB "value"
export PERL5LIB
