Guys,

Doing a quick backup of config files (like .bashrc) from within
bashrc and I need to find a better way to find the total number of
files matching a glob in a directory. Currently I'm using:

total=$(ls $budir/bashrc-* | wc -l)

to determine how many copies I have in my bashrc.tar.bz2 backup +
the new one I just copied to the backup location so I can determine
the number to delete to just save the last 3 when I tar it up again..

The ls | wc combination works fine, but I don't like the fact that
there is a pipe in the middle of it. If there is a cleaner way to do
it, let me know.

I can't get rid of the pipe for you, but personally I'd do:

total=$(find $budir -iname bashrc-* -type f | wc -l)

That barfs if you're in the directory with the bashrc files.
You need to add single quotes around the -iname arg.

Or add a backslash, whic I always do:

total=$(find $budir -iname bashrc-\* -type f | wc -l)
