Isolate file name from full path/find output

Quick method of isolating filenames from a full path using expansion.

Much quicker than using "basename"


There are 2 alternatives - vote for the best!

What others think

That's not much quicker than:

echo $(basename $fullpath)

But basename is certainly less cryptic.

Using "find /" to get all files on my box, it took the expansion version 45 seconds to isolate filenames whilst "basename" took 14 minutes.

That's a hell of a lot quicker.

Yup, that's a "feature" of find we have to work with.

In addition, there are no problems with expansion when reading filenames from a file.

ie find / > tempfile; cat tempfile | while read fullpath; do echo "${fullpath##*/}"; done; rm tempfile
