Or more specifically `${1%.tar.gz}` – tripleee Sep 03 '11 at 11:21
@tripleee yes if we are sure that the file name ends with .tar.gz – Mu Qiao Sep 03 '11 at 11:23
if you know the extension, `$(basename $1 .tar.gz)` also works. – jedwards Sep 03 '11 at 19:26
@jedwards I don't want to create a new process for such simple case. – Mu Qiao Sep 04 '11 at 00:50

Using bash and GNU parallel:

$ myFilename=`find . -maxdepth 1 -name *.gz -print0 | parallel -0 echo {.} | parallel -0 echo {.}`
$ echo $myFilename
./temp

Not as clean as the other approaches, for sure, but it will work with filenames with spaces in them.
