use teh globs, luke ;)
for t in /usr/bin/gcc-3*; do # will already do this, sorting according to
LC_COLLATE order (set to C or POSIX [same thing] for ebuild.) There's no
need to step through every one either:
t=(/usr/bin/gcc-3*); [EMAIL PROTECTED]: -1}; unset t # get rid of array storage
(using same var for both, eg [EMAIL PROTECTED]: -1} only sets the first cell;
the
rest of the array is still live. var is a synonym for var[0] in BASH.)
set -- *
t=${@: -1} # works here as well but dunno if that applies to all sh (the -1
expansion, not the set.) In any event not needed in BASH since arrays make
our life so much easier ;)
cf: /msg greybot ls and http://wooledge.org/mywiki/glob -- remember you can
do, eg: for i in portage/*/*foo*/*.ebuild
or a more common example: for f in */*/.jpg
It's not find, but it is efficient and filename-safe.

(Please, no complaints about not using spaces in filenames, there's no
telling where your script could be used-- if it's written correctly.
Subshells and externals as well; why fork and waste resources we don't have
to?)
