in thread untarring number of files

Why are you using Perl?

Maybe he was just sticking with what he knows... and trying to write portable code.

for file $(ls -1 *.tar)

First, the error: you need for file in. Secondly, that has portability issues. $( ) works with some Bourne-like shells, such as bash and ksh, but it isn't ubiquitous. You could probably get away with for file in `ls -1 *.tar` but there is really no reason that I know of not to just use a glob like for file in *.tar instead.

    Perhaps I'm missing something as well, but having the for loop iterate over the results of 'ls -l' doesn't seem like it'd work, as it would try to untar things like '-rw-rw-r--' and 'Oct'. Perhaps 'ls' would be more appropriate. Heck, you could even leave the external program out of it. 
    for file in *tar; do tar xvf $file; done

      That's a "one". ;) Gets us all...

       You misread '-1' (dash one) as '-l' (dash ell).

       Using -one only produces the filenames and nothing else, so your point isn't a problem.

       Of course this loop does fail for cases where the filename contains either a space or a " character in their names ..
