@RudiC and @Don


the file is located in ~/bin (see above)


error message
Code:
~/bin$ sudo cleanup2
sudo: cleanup2: command not found

permissions
Code:
~/bin$ ls -l cleanup2
 -rwxr-xr-x 1 m***** m***** 459 Jan 28 15:07 cleanup2


~/bin$ ls -l cleanup3
-rwxr-xr-x 1 m***** m***** 2057 Jan 29 06:13 cleanup3

shebang
Code:
#!/bin/bash
   # Proper header for a Bash script

As far as differences, go, I can't find any. Cleanup3 runs fine, but Cleanup2 won't.
Don, I tried locate cleanup and found some other files containing that string, but they aren't in $PATH
Note that cleanup2 and cleanup3 are not the same as Cleanup2 and Cleanup3; case matters in the shell command language!

What output do you get from the commands:
Code:
od -bc ~/bin/cleanup2 | head -n 10
od -bc ~/bin/cleanup3 | head -n 10
