[SOLVED] a short shell script related to PIDs

gujedan · 11-21-2010, 09:15 AM

how can I store the output of (ty to colucix for this line)

Code:

xprop -id $(xprop -root | awk '/_NET_ACTIVE_WINDOW\(WINDOW\)/{print $NF}') | awk '/_NET_WM_PID\(CARDINAL\)/{print $NF}'

in a variable and then pass the value of that variable to the kill command as the PID to kill?

Are you looking for command substitution?

Code:

variable=$(xprop -id $(xprop -root | awk '/_NET_ACTIVE_WINDOW\(WINDOW\)/{print $NF}') | awk '/_NET_WM_PID\(CARDINAL\)/{print $NF}')
