To speed up commands try batching them.
Instead of the following to delete files older than 30 days in a
script:
#!/usr/local/bin/ksh
find /mypath -type f -mtime +30 -exec rm {} \;
exit $?
Try using a "+" instead of the usual "\;"
Such as:
find /mypath -type f -mtime +30 -exec rm {} +

Hmmm..apparently this works on certain versions of "find". It works on Solaris, but isn't documented...but doesn't seem to work on
my version of "find" on 4.7 STABLE. But is in the draft of POSIX.1
I'll have to try this on different boxen and see what happens.

Apparently some (all? ..not sure) SysV versions of find will
execute a single command and pass to it the file name arguments rather than executing the command for each file name found.
So a command of:
find . -exec chmod u+w {} +
will execute a single chmod command and pass to it the arguments
rather than doing a chmod for each filename.
I didn't know at the time I posted that it doesn't work on FBSD
but if anyone finds themselves at a SysV system, they may want to try it out.

find . -name zot6 -exec chmod u+w {} \;
The above command worked for me in the bash shell of a
freeBSD system. I added the "-name zot6" part to make sure that the exec only modified the file that matched the search criteria.
We are using bash version 2.05a and freeBSD version 4.6

Hi folks,
FreeBSD 5.2.
Dose ksh refer to Korn Shell (ksh)?
If YES, I could not locate CDE (Graphics and ksh) nor dtksh nor on my PC nor on /usr/ports/
# cd /usr/ports
# make search -i name=dtksh
# make search -i name=CDE
Kindly advise. TIA
B.R.
