A different change you can make to ~ldm/bin/scour makes it much more
efficient and is supported on all platforms:
change:
find . -type f -mtime +$FINDAGE -name "$pattern" \
-exec rm -f {} \;) && touch "$edir/.scour$pattern"
to:
find . -type f -mtime +$FINDAGE -name "$pattern" \
-print | xargs rm -f ) && touch "$edir/.scour$pattern"
Here a list of files to be deleted will be passed to 'xargs' which will run
'rm -f'. 'xargs' will break up the command line into as many pieces
it needs to do all of the scouring. The original scour code execs
'rm -f' for each file that is to be deleted.
The modified 'scour' can be found in the pub/ldm/scour directory
of anonymous FTP on our FTP server, ftp.unidata.ucar.edu.
The modification listed above will be included in future LDM releases
(it is not in ldm-6.0.14 or ldm-6.0.15).
