Hi, I put this text in /etc/environment:
$ source /etc/environment
ip="$(ifconfig | grep -A 1 'eth0' | tail -1 | cut -d ':' -f 2 | cut -d ' ' -f 1)"
$ echo $ip
192.168.0.33
Works fine, but when I reboot my archlinux:
$ echo $ip
$(ifconfig | grep -A 1 'eth0' | tail -1 | cut -d ':' -f 2 | cut -d ' ' -f 1)
What's happened?? Is necessary exec source /etc/environment after every reboot?
Thanks in advanced.
/etc/environment is for PAM not shell, so it only allows ip=xxx.yyy.zzz.aaa . Also, /etc/profile is for LOGIN shells, meaning that from scripts or when doing scp(1) it won't be read. What exactly are you trying to achieve?

I need define variable called ip with current ip address machine... And when reboot machine, the variable ip always has ip address.
