Speeding up a find and subsequent grep

[Jeffrey Walton]

Hi Everyone,

I'm working on CentOS 7, x86_64, fully patched. The server has a
manual wiki installation. Ownership and permissions need to be set
after an update. I've got a script that does it. The slowest part of
the script is this:

# Make Python, PHP and friends executable
IFS= find "$WIKI_DIR" -type f -print | while read -r file
do
    if file -b "${file}" | grep -q -E 'executable|script';
    then
        chmod u=rwx,g=rx,o= "${file}"
    else
        chmod u=rw,g=r,o= "${file}"
    fi
done

Some of the files have whitespace in their names so I need something
like 'find -print | while read'.

When I added the 'file -b' piped to 'grep -E' the script slowed down
considerably.

Is there any way to speed up that portion of the script?

Thanks in advance.

Jeff
