    Hi, ++davidrw
    or even
    $ perl -MFile::Spec -le 'print File::Spec->rel2abs( __FILE__ ) ;' /home/svenXY/-e # for a one-liner

    File::Basename is not necessary here.
      OP said I have a module that needs to know its path in order to access another file in the same location. -- the second step of File::Basename is to fulfill that requirement (even though he didn't directly ask for it).

      Other shell (bash) solutions:
      # setup cd /var/tmp/ touch foo f='../../var/tmp/foo' # for just the directory: d=`(cd ${f%/*} && pwd)` #or: d=`dirname $f` d=`cd $d && pwd` # for the filename (rel2abs): d=`dirname $f` d=`cd $d && pwd` f=`basename $f` f=`/bin/ls $d/$f`

    This works; thanks! The 'funky' aspect to which I referred is that when invoked from a script, the module's __FILE__ is 'XML/'. When invoked from the command line:

    perl -e "use XML::Foo; $x = new XML::Foo;'

    its __FILE__ is reported as '/XML/' -- which is clearly bogus.

    It has been suggested that the latter behaviour is due to Red Hat's patches for Fedora Core 8.

    Whatever, you've given me the solution. I guess I'll just have to wait and see if it works in all cases, or if there are edge conditions where it goes blooey.
