zsh script can't find zsh binary?

zsh script can't find zsh binary?

[Jose Unpingco]

Hi,

I have a very simple script. It looks like this..

#!/home/sunshine/grad/unpingco/bin/zsh
echo 'hey'

the script file is listed as...

-rwx--x--x  1 unpingco       50 Jun 25 10:05 cf.zsh*

and the binary for zsh is in

-rwx------  1 unpingco   475136 Jun 24 13:44 bin/zsh*

and the full pathname to zsh is

/home/sunshine/grad/unpingco/bin/zsh

when I try to invoke it on the command line as

zsh> cf.zsh

I get 

zsh: command not found: cf.zsh

I can't figure this.  I've shuffled the permissions every which way and it still
won't work.  Something is weird here. I'm out of ideas.

any help much appreciated.

This looks like a classic case of the interpreter exec line being too
long! One of the sillier features of unix lookalikes.

There is usually a limit on how long the #! line can be, 32 characters
or so. The error message always complains it can't find the script
file, not the interpreter. You've passed the length limit. This is a
kernel problem, rather than zsh. :-)

Basically you're stuck. You need to put it in a directory with a
shorter pathname, or use /bin/sh as a bootstrap to run zsh, or run
your script as a zsh function instead.

Bummer eh?

Dave.

This isn't the problem here.  The limit is 64 characters, and the message for
exceeding this is: "exec format error". (It has nothing to do with the kernel)
Another possibility could be that the program's not in his path, and he should
do ./cf.zsh

On which platform?  On a Sun4 (SunOS 4.1.3) the limit is 32 characters
and the error message from zsh is without an explicit path for the
executable is:

    zsh: command not found: fog

And the error you get with an explicit path is:    
    
    zsh: no such file or directory: ./fog
