export LINUX_VERS=`head -n 1 /var/log/dmesg`

if that works, no need for the if fi

which user is it checking? cause if its checking root you have to edit the .bashrc in the /root directory

also worth noting... you need root permissions to access the dmesg file so that could possibly cause a problem if you do it as a normal user, have you tried doing it in a root session?

and make sure you use a back tick instead of a single quote
Kinda meh now...

it wont let me edit my posts whenever im not home for some reason >_> just read it a little better, the if fi has nothing to do with your variable sorry lol

just try throwing export in front, make sure you use a backtick, and sort out your permissions with dmesg (possibly just by doing it as root), and make sure you edit the right .bashrc file (in the /root dir for root)

It checks the current user's directory, so, that would be the one I am working on.

Not sure what you mean by "you need root permissions to access the dmesg file", as I can view the dmesg file without root access.

Yeah, I am using the back tick, and not the single quote. That was my first mistake before I realized and corrected it.

well i tried to just do

head -1 /var/log/dmesg

in my terminal, and it kicked back permission denied perhaps your permissions are set differently...

still i would try throwing on the export in front of the line, see if that works... generally if i set an env variable, i export variable=value

Yeah, export didn't solve it either. Still gives me that 0, however, the command still exports the first line of the file and it matches that of required text. :|

It doesn't for me?

Pastie

I will try using that command though.

EDIT:
Yeah, still nothing:

(Getting rid of export doesn't work either)

echo your variable to check if not, try switching out the stuff in your back ticks to the cmd that the cow just posted

just had to check myself and it does work as a normal user

so

export LINUX_VERS=`dmesg | head -1`
