I tried this on Linux (bash)
x=`ls -t | head -1`; if [ -f $x ]; then echo $x ; else echo "NO" ;fi
and "NO" kept being printed. I tried just the first part to set x
and then "echo $x" and got a file name 'xxx', so the 'if...' should work
(but it does not). When I tried "if [ -f xxx ]; ..." then it worked.
So for some reason in bash, the '-f $x' is not being interpreted properly.
I even tried on the command line...
# x=xxx
# echo $x
xxx
# if [ -f $x ]
> then echo $x
> else echo NO
> fi
NO
# echo $x
xxx
#
So it still won't work but $x *is* correct.
I gave up and wrote the Perl script instead :)
Thanks... Dan.
