I have a crontab job setup. In the crontab file, I have a path to a text file. My text file has a wget command (which in turn, executes a PHP file). If the crontab file just has the path to the text file, will it automatically bash (execute) that text file? Or do I need to prefix the path to the text file with bash?

You can try it out by copying the "command" portion of the line into a shell, and pressing return. If it says "Permission denied" or another error, then you'll need to check things as suggested by other answers. – fredden Mar 4 '10 at 20:08

If the file is executable (check if it has x in ls -l, if not, then use chmod to set the executable bit) and the first line contains #!/bin/bash then it will be interpreted in bash.

The other option is, as you suggest, to pass it as an argument to bash:

/bin/bash /path/to/your/

Thanks mate! I will take care of this now. – StephenPAdams Mar 4 '10 at 22:21
So, my script should do the following: 1stline: #!/bin/bash 2ndline: wget insertweburl here Is that correct? – StephenPAdams Mar 4 '10 at 22:23
Correct. And use chmod +x <file> to set the executable bit. Also, you should probably use the full path to wget, since cronjobs usually run a "bare" environment where $PATH might not include the directory where the wget binary resides. – Mikael S Mar 5 '10 at 4:44
