shabang lines don't work on my guru plug

[msrk]

I have a new GuruPlug.  I put a perl script on it with the following shabang line.

  #!/root/bin/bin/perl -w

When I run the program from the command line I get the following message.


  guru:~/bin$ ./ms_sync.pl
  -bash: ./ms_sync.pl: /root/bin/bin/perl: bad interpreter: Permission denied

When I run 'which perl' the path I used is confirmed.
This perl script works on several other debian computer and it works with no problem.

I can run perl and I can invoke the script as an arg to perl like this:

  guru:~/bin$ perl ms_sync.pl

Which works fine.

I think this has something to do with the way the root partition is mounted.  However, there seems to be a little guru black magic going on to get the root partition mounted since it isn't in /etc/fstab.  If I enter mount on the command line I find the following line.

rootfs on / type rootfs (rw)

I cannot tell how it is mounted.

bash, perl, python, etc work but they all have this problem when invoked via a shebang line.

How can I get shebang lines to work?

Thank  you,
Marc

are you sure that perl is in /root/bin/bin/

the double bin seems strange

what does 'which perl' gives?

On my Guruplug Server +:

Code:

~$ which perl
/usr/bin/perl

Moreover, if your program contains

Code:

#!/usr/bin/perl

and is made executable

Code:

chmod +x ms_sync.pl

you can run it directly without calling the perl interpreter:

Code:

./ms_sync.pl

Thank you for your replies.
The bin/bin is a typo only in the message posted to this group.   In the script it is /usr/bin/perl.

Yes, I have made hundreds of scripts with the shabang line and +x permission.  That is why this is so strange that it doesn't work here.  None of the shabang lines in any of my scripts  work.  I think this is some problem with the way the rootfs is mounted.

I will appreciate any help.  Also, please let me know if you are expiencing the same thing on your GuruPlug.

You probably edited this file under windows or something and the shebang line actually ends with <cr><lf> instead of the unix <lf> only.  Do "od" on it, like so:

od -cv /path/to/the/perl/script

and verify the line endings.  Use "dos2unix" to convert the file back to unix line ending convention.
