If I have a subshell command:
output="$(runfoo)";
is there way to store only the last line of the output from runfoo
into the variable output
? Or perhaps only the first line?
Only stdout:
output="$(runfoo | tail -n 1)"
output="$(runfoo | head -n 1)"
Stdout and stderr:
output="$(runfoo 2>&1 | tail -n 1)"
output="$(runfoo 2>&1 | head -n 1)"
