I don't know if this is of interest as an alternative.
I did find a cool functionality called locate and updatedb
Updatedb creates the database of your files, locate does superfast
searches.
It essentially does a superfast "find" on your root filesystem, giving
you the fully qualified path of all hits.
You can create db's on your other filessytems.
The problem is that it can get stale, but you can update it before doing
your searches. Plus it gives you a fully qualified path name with the
results.
So if you need to do a set of searches on a filesystem (or whole system)
run updatedb on each target filesystem to create the db for that
filesystem.
then use locate to search each filesystem "db"...
it takes seconds like ls instead of minutes like find....the more files
in the FS, the quicker the searches compared to other tools.
the best part is you can run the db's when your systems are quiet, and
the databases use minimal diskspace.
Dan,
Thanks for responding. I've been using those two utilities for a long
time, and they are indispensable. But they don't solve the issue I'm
having. Consider the case where there are multiple files with the same
name but different paths. Also, it takes quite a while for the data
used by those utilities to update, much too long for an interactive script.

This should be simple, but it's not, unless I'm forgetting something.
Writing a script, an arg is a filename. So
fname=$1
But I want that expanded to include the full path and filename, not
just what is given as the arg on the command line.
E.g., if the user's cwd is /home/joe/a/b/c/ and he specifies
../x/file-a.ext
then the function/utility should transform that into the absolute path
with filename:
/home/joe/a/b/x/file-a.ext
In the simplest scenario, the answer would be $PWD/file-a.ext, but
that would by no means cover a portion of the possible scenarios.
You'd think this functionality would be included already in one or
another linux utility. It's kinda like the complement to the
'basename' utility. I've looked into the dark corners of ls, stat,
file, bash, type, find, and a few other linux standards, but nothing
seems to do this.
Any gurus out there know the utility which does this?
