That code's just ugly anyhow. We shouldn't have to call top, when we
can call ps to do the same thing...
ps -eo 'pid,pcpu' | awk '$1 == "'$1'" { sub(/(\.[[:digit:]])*$/, "",
$2); print $2 }'
Example:
ps -eo 'pid,pcpu' | awk '$1 == "1" { sub(/(\.[[:digit:]])*$/, "", $2);
print $2 }'
0
ps -eo 'pid,pcpu' | awk '$1 == "'$(pidof xfce4-session)'" {
sub(/(\.[[:digit:]])*$/, "", $2); print $2 }'
0
ps -eo 'pid,pcpu' | awk '$1 == "'$(pidof vfork)'" {
sub(/(\.[[:digit:]])*$/, "", $2); print $2 }'
99
That's been committed to CVS.
Thanks for the report!
