bad interpreter: No such file or directory

carric has asked for the wisdom of the Perl Monks concerning the following question:

I am stumped.. I have a script for which I have verified perl is indeed where it should be, but if you execute it like this:


it gives the message

: bad interpreter: No such file or directory

IF you go into the script and change

#!/usr/bin/perl -w

It executes.. but there are SO many errors, it doesn't work (it's a CGI script from somebody, that has "issues").

Has anyone ever seen this?? It has some "require" statements for some other perl chunks, and I was wondering if that had anything to do with it, but I edited a few scripts, and it doesn't seem to affect anything.

The script lives on a local file system, and has proper permissions.

Thanks a lot ahead of time.


I did not see any control chars, but ran dos2unix anyway on it, and then it started working. Really strange.

Thanks everyone!!

    Check for control characters on the end of the lines - normally caused by copying scripts from one platform to another without correcting the line endings.

    If the information in this post is inaccurate, or just plain wrong, don't just downvote - please post explaining what's wrong.
    That way everyone learns.

      Thank you... It saved a lot of time for me.

    If you FTP in binary mode (or otherwise copy) from a Win32 box to a box that's some variant of Unix, you have an invisible hidden carriage return (^M) at the end of each line. The "bad interpreter" that's being referred to in this case is   /usr/bin/perl^M
    Copy the file in ASCII mode, or use dos2unix (or the equivalent), and your problem will probably go away.

      Or just make sure you have spaces after /perl, something like #!/usr/bin/perl -w  -  
      or use dos2unix (or the equivalent)
      Or of course use perl with the p and i switches.. perl -pie's/\r\n/\n/g;'

    This happens when executing scripts with a different line endings pattern different to that of the system you are running. Since it seems you are running on a linux system, open your script in an editor like geany then convert line endings to unix style. This is also encountered with apache. Regards.
      I ran into this same issue. Thanks for the help. It worked after removing the ending characters. I wrote my pl script in Notepad++ (windows), which was causing it.

    use dos2unix
      Sometimes, dos2unix complains it can not convert. But in linux, do a vi edit on this file, and add a space at the end, delete it , then save it for VI to understand it has to 'resave'. It became fine. Need time to debug this issue.
