Is it acceptable to use `grep` to check for the presence of a string in a file within an init script?

Is it okay for me to check the contents of a file for a given string with grep in an init script?

I am concerned about introducing dependencies and general convention when it comes init scripts, and if running grep or other tools violates some credo.

    iniscripts can do whatever they want. Of course it makes sense not to introduce new dependencies, just for the initscripts. grep however is fine on pretty much any system that's posix/susv3 compatible (linux, bsd, solaris, other derivatives).

  2. In short, YES. So long as the file you are looking for is mounted at that point.
