Hi there

How can i get the result of:

ls /sys/class/net | grep wlan

into a bash variable wX

Thanks.

Hi!

Use the backtick (`) character around the command:

Code:

gp@mariachi:~$ wX=`ls /sys/class/net | grep wlan`
gp@mariachi:~$ echo $wX
wlan0

hope that helps

Code:

wX=`ls /sys/class/net | grep wlan`

edit: greenpeace was a little faster =)

Pedantic note: it's better to use $( ) rather than backticks: http://mywiki.wooledge.org/BashFAQ/082

As you were!
