How to search for the sessions that have a certain environment variable set?

Hi all,

In Solaris 10, is there a way to search for the sessions that have a certain environment variable set?
# 2  
Does Solaris 10 have the /proc file system?
This works on linux:
Code:
sudo grep "TERM=linux" /proc/*/environ
Binary file /proc/1258/environ matches
Binary file /proc/1378/environ matches
Binary file /proc/1380/environ matches
Binary file /proc/1396/environ matches
Binary file /proc/1397/environ matches
Binary file /proc/1420/environ matches
Binary file /proc/1/environ matches
Binary file /proc/966/environ matches
Binary file /proc/self/environ matches
Binary file /proc/thread-self/environ matches

Try
Code:
env

or
Code:
 cat ~.profile

or
Code:
/etc/default

If by sessions you mean processes, this should be what you look for (replace VARIABLE by the name of the variable you are interested in):

Code:
for i in /proc/*; do
    pargs -e $i | grep VARIABLE= && ps -f -p $(basename $i)
done 2>/dev/null

Do it as root if you need to search processes you do not own.

All,

Thanks for your suggestions. I did a test with the DISPLAY variable, I have set it in my session and I get to see it when i use env, however when I look for it with pargs -e it's not there.

I'm looking to find the PID of the session that uses a certain value for the DISPLAY variable, so I need to search after the value of the variable also.

Have you set it in a shell? Then you need to export it.
Code:
bash$ export FOO=bar
bash$ pargs -e $$ | grep FOO=
envp[7]: FOO=bar

and is also found with jlliagre's method.

I have exported the DISPLAY variable but for some reason it doesn't show up.

Code:
user@machine:/home/user>env
_=/usr/bin/env
SSH_TTY=/dev/pts/1
PATH=/usr/local/bin:/usr/bin:/bin
EDITOR=vi
LOGNAME=user
MAIL=/usr/mail/user
HOSTNAME=machine
USER=user
DISPLAY=10.5.205.232:236
SHELL=/usr/bin/ksh
HOME=/home/user
SSH_CONNECTION=129.121.221.47 53939 10.13.22.201 22
SSH_CLIENT=129.121.221.47 53939 22
TERM=xterm
PWD=/home/user
TZ=US/Central
ENV=/home/user/.kshrc
user@machine:/home/user>pargs -e $$
2925:   -ksh
envp[0]: USER=user
envp[1]: LOGNAME=user
envp[2]: HOME=/home/user
envp[3]: PATH=/usr/bin:/bin
envp[4]: MAIL=/var/mail//user
envp[5]: SHELL=/usr/bin/ksh
envp[6]: TZ=US/Central
envp[7]: SSH_CLIENT=129.121.221.47 53939 22
envp[8]: SSH_CONNECTION=129.121.221.47 53939 10.13.22.201 22
envp[9]: SSH_TTY=/dev/pts/1
envp[10]: TERM=xterm
