Help on the shell script.

Gulam Mohiuddin — Wed, 24 May 2006 09:05:03 GMT

My following command is working fine, but now the number of directory names I need to prune is getting bigger in turns this command is getting larger and larger.

find /psoft -mtime +30 -name "PSDSTSRVLOG" -prune -o -name "PSPRCSRVLOG" -prune -o -name "TUXLOG" -prune -o -print | xargs rm -rf

Is there any way I can shorten this command while accommodating more directory names?

for examles.

prune_dir_list=PSDSTSRVLOG PSPRCSRVLOG TUXLOG TUXLOG2 TUXLOG3 TUXLOG4..

find /psoft -mtime +30 -name $prune_dir_list -prune -o -print | xargs rm -rf

Thanks,

Gulam.

You should have no problems.

prune_dir_list="PSDSTSRVLOG PSPRCSRVLOG TUXLOG TUXLOG2 TUXLOG3 TUXLOG4"
for x in $prune_dir_list
do
find /psoft -mtime +30 -name ${x} -prune -o -print | xargs rm -rf
done

Hi Gulam:

You could use a pattern file with 'grep' to perform filtration, something like:

# find /path -xdev -type f -mtime +30 | grep -v -f /tmp/skippatterns | xargs ls -l

Gulam,
you may also want to have a look at the gnu version of find, which has a wide range of additional useful parameters, documented at:
http://www.gnu.org/software/findutils/manual/html_mono/find.html

Hi,

you can generate an option list for find:

prune_dir_list='PSDSTSRVLOG PSPRCSRVLOG TUXLOG TUXLOG2 TUXLOG3 TUXLOG4'

findopt='-mtime +30'
for entry in $prune_dir_list
do findopt=$findopt" -name $entry -prune -o"
done

find /psoft $findopt -print ...
