For starters, you must not put spaces between elements of a directory or path.

You wrote your command as:

'pgrep devmon &> / dev / null || / usr / bin / devmon &> / dev / null’

This should be written:

'pgrep devmon &> /dev/null || /usr/bin/devmon &> /dev/null'

What the terminal is telling you is that all it sees is ‘/‘ and that represents the root directory.  Since you can’t output to the root directory, your command fails.
