grep into a variable in bash

[9anth3r]

Got a quick question,

Right now im executing the command's

ping localhost -c 2 >> backup.tmp
grep '100% loss' backup.tmp


how do i get the grep output (if there is any) into a variable ?

Any tutorials on SH would be much appriciated as would any help.

Hi,
But since you are greping for a Known Quantity aren't you just really looking for the STATUS of grep whether it found your pattern or not? Why do you need the line stored in a variable?

grep '100% loss' backup.tmp
if [ $? == 0 ]; then
echo &quot;ALL was lost&quot;
fi

Thank's guys,

Just switched from C++ to shell scripts and haven't had hardly any sleep, just couldn't think today.

Thanks
