I have a little perl script that I can't execute properly. The problem
is making it executable, not the script itself.

Here is what I am doing: the script is sitting in a directory 'bin' in
my home directory. It's executable, and my PATH is set to include
/home/uuser/bin:

m2:~$ cd
m2:~$
m2:~$ ls -l | grep bin
drwxr-xr-x 2 uuser sndusrs 4096 Feb 14 02:09 bin
m2:~$
m2:~$ ls -l bin
total 16
-rwxr--r-- 1 uuser sndusrs 5387 Feb 14 02:08 rgrep.pl
m2:~$ echo $PATH
/usr/local/bin/ <snip> /home/uuser/bin

But when I try to execute it, I get:

m2:~$ rgrep.pl
bash: /home/uuser/bin/rgrep.pl: No such file or directory

What am I doing wrong?

Thanks!

That misleading error message usually indicates that the first line of
the file is of the form:

#! <prog>

but <prog> is either invalid or not executable. Does it match the
precise location of your perl?

That typically happens with scripts that start with:

#!/bin/prel
or
#!/no/such/file

It could be that your CWD is not in your path. Try using the form:

./myprog.pl

Advanced users use scripts copied from a Windows machine without removing
the leading linefeeds. This is harder to figure out and thus produces much
more fun.

The script can only be executed by user uuser, are you that user ??

Try:

./rgrep.pl

Since the script isn't in his CWD, it's in his bin directory (which he
showed is in his PATH), that can't possibly work!
