This finds a all directories and files which name contains {word} that
are located in and below {path}.  It doesn't find files that contain
{word}.

This stores all file and directory names that are in / and below
in /usr/local/where/was.txt

This takes the list of files and directories from above and searches for
the first command line argument ($1) in that list and stores what it
finds in /usr/local/bin/ww

This makes /usr/local/bin/ww executable to everyone.  It's unlikely at
this point that /usr/local/bin/ww is a correct shell script.

This tries to execute the file that was just created with {word} as it's
first command line argument.

This tries to execute the file that was just created with tgz$ as it's
first command line argument.

The -v option to grep inverts the match, so grep -v proc would search
for lines not containing proc.

If I read chalonec's question correctly, he wanted to "search all files
in all directories and sub-directories on a disk for files that contain
a certain text string such as the word gateway or mode or any word."
Paul Howarth answered that question very well, so I won't answer it
again.  I was just trying to understand how your solution solves the
problem?
