Re: script-problem

You forgot to make your script executable, as this demo shows:

   $ ls -l /usr/bin/perl 
   -rwxr-xr-x    2 root      root   2478418 Jan 16  2004 /usr/bin/perl
   $ rm -f print.pl
   $ echo '#!/usr/bin/perl' > print.pl
   $ echo 'print "Hello, world\n"' >> print.pl
   $ ls -l print.pl
   -rw-------    1 anonymous monk        39 Oct 20 11:33 print.pl 
   $ ./print.pl
   bash: ./print.pl: /usr/bin/perl: bad interpreter: Permission denied
   $ chmod +x print.pl
   $ ls -l print.pl
   -rwx------    1 anonymous monk        39 Oct 20 11:33 print.pl
   $ ./print.pl
   Hello, world
[download]

It's not that your she bang line is wrong as a previous poster suggested. If that was the case, you would get the message:

    $ bash: ./print.pl: /usr/bin/perl: bad interpreter: No such file o
+r directory
[download]

which you would also get if there were "unreadable" characters after 'perl' as the other posted suggested.

Maybe your script is on a filesystem mounted with the `noexec` option. do any other (non-perl) binaries or scripts work in that directory? "What should it profit a man, if he should win a flame war, yet lose his cool?"	[reply] [d/l]

i'm sorry, that is not the case either. snippet from my /etc/fstab: `/dev/hda7 /data ext3 user,auto 0 + 0` [download] i don't know if that matters, but i use debian unstable. and i'm quite lost with my problem right now :(...	[reply] [d/l]

ok, i'm sorry, i fixed the problem. the filesystem wasn't mounted with the noexec option, but it wasn't mounted with the exec option either. after adding that to /etc/fstab everything works well now. thanks for your help!	[reply]
