No need for grep if using awk:

Code:

awk '/XkbLayout/ && !/^#/ {gsub(/"/,"",$3); print $3}' /etc/X11/xorg.conf

How about a little less awk? set makes a handy substitue for awk when simply printing out a certain field:

Code:

set $(grep -e XkbLayout /etc/X11/xorg.conf | grep -v "^#")

echo $3

Too bad about the two calls to grep, but case makes a handy substitute for simple pattern-matching. To keep it all in bash:

Code:

while read LINE ; do

    case "$LINE" in

        \#*) : ;;

        *XkbLayout*) set $LINE ; echo ${3//\"/} ;;

    esac

done < /etc/X11/xorg.conf

a few methods!

Code:

grep -e XkbLayout /etc/X11/xorg.conf | grep -v "^#" | tr -d \"

Code:

$ x='"fish"' 

      

$ echo $x  

"fish"



$ echo $x | tr -d \"

fish



$ eval echo $x      

fish



$ echo ${x//\"/}

fish
