Hi,
ping geekcrossing.net|perl -le "m/time=(\d+)/;print $1";
Can some one help me with the above command
Add an n to the perl arguments to get it loop over stdin and use
single quotes to prevent shell from trying to interpolate $1.
ping geekcrossing.net|perl -nle 'm/time=(\d+)/;print $1';
Also, you should probably write it like this:
ping geekcrossing.net|perl -nle 'print /time=([\d.]+)/ ? $1 : "time not found"';
or this
ping geekcrossing.net|perl -nle 'print $1 if /time=([\d.]+)/';
