unzip and keep original file ?

Blaumieser · 09-19-2005, 05:02 PM

Hi all,
this problem seems very small but I cannot find a solution: When using unzip on an regular zip-file the contents are extracted and the original zip file is gone. I want to extract and keep the original file. How can this be done besides always making a copy with another name or in another place? There seems to be no option mentioned in the corresponding man page...

Thanks in advance

unzip does keep the original zipfile, unless you're using gzip? But then that doesn't handle multiple files to compress (hence it's used with tar).

Oh, didn't know that. Yes, I used gzip but I thought zip behaved like gzip. I will investigate further if there is an option to tar xzf that keeps the original...

Thanks!

tars z option also won't delete the tarball. The only real concern is
with using gunzip on a .gz file. And that can be fixed by using
gunzip -c blurb.gz > blurb

... cool! That's a nice trick.

Thanks again!

Heh - it's not really a trick, it automatically follows from
reading the man-page ;}
