A common error is to make bad assumptions about the current work directory.

The only difference between system() and the command line is that the shell is interactive in the later. This can affect which startup files the shell executes, which could affect stuff like aliases.

Finally, the command you're running via system might be different than the one you run from the command line. You should check the contents of the relevant variables.

And that's assuming you're running the command as the same user.
