Thank you, that works!
One slight problem however. When I run the code from the parent directory, and say: (edited to be more specific)

Code:
#!/bin/ksh

cd /path/
if [ ! -f file ]; then
echo "/path/" >> bad.txt
fi

I get no output. It appears that for some reason it's not changing to the directory and running the if statement, but rather running the if statement in the parent directory. How would I go about fixing this?

NAME

       script - make record of a terminal session

SYNOPSIS

       script [-a] [filename]

DESCRIPTION

       The  script  utility  makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the
       record is saved in the file typescript. See WARNINGS.

       The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends
       when the forked shell exits or when Control-d is typed.

OPTIONS

       The following option is supported:

       -a	Appends the session record to filename, rather than overwriting it.

NOTES

       script places everything that appears on the screen in filename, including prompts.

WARNINGS

       script  can  pose  a  security risk when used in directories that are writable by other users (for example, /tmp), especially when run by a
       privileged user, that is, root. Be sure that typescript is not a link before running script.
