I didn't take the time to figure out exactly what you are doing, but
42 subdirectories just looks wrong -- whatever your problem is, there
has got to be a simpler solution. It wouldn't surprise me if you are
approaching a limit that nobody could figure out a reason to extend.
If you just need to 'test -e' maybe if you change '/' to '.' in your
scripts and only have one directory with one file for each of your
records, that would be simpler?
/TMP/1.2.3.4.5.6.7.8.9.0.1.2.3.4.5.6.7.8.9.0.1.2.3.4.5.6.7.8.9.0.1.2.3.4.5.6.7.8.9.0.1.2
then you could use shell expansion (ls /TMP/1.2.3.*9.9.9.*) and regex
('5.6.7.8$') to select your files for catting. At least that would be a
relative easy stepping stone to, say, a bash array, data structure.
or you could put the 42 character parameter, in a file, followed by a
tab and a value, and test if `grep $parm | sed 's/.*\t//'` is an empty
string || use it's value...
All I'm saying is anything with 42 subdirectories is bound to have a
simpler solution. Application or OS development, choose your poison.
