Silly bash script needed

[thedaver]

I want to create a .tar-chive of the files that match a grep

"grep -Hl sutton *"
"tar zcf sutton.tar.gz"

how do I pipe grep's output of filenames into the command line parms read by tar?

Did you try: grep -Hl sutton *|tar zcf sutton.tar.gz

Yeah, tar borks:

"tar: Cowardly refusing to create an empty archive"

I did it this way:

# grep -Hl sutton * > temp.txt
# tar zcf sutton.tgz `cat temp.txt`

I *thought* that your way was the right way, but I apparently have more to learn about how tar handles piped IO. Situation solved, mystery remains.

Thx aixmurderer. Still open to discussion.

tar zcf sutton.tgz <grep -Hl sutton *

Plamb, that will totally not work.

tar zcf sutton.tgz $( grep -Hl sutton * )

backticks have been depricated for about 8 years now,
the $( ... ) syntax nests better and is more readable.
