Please can anyone help to enhance below scripts.I getting "/usr/bin/mv: 0403-027 The parameter list is too long" error when executing below script.So i have tired to change ulimit -f to unlimited but still same .Some people suggested to use xargs but I'm not sure how to apply in my script.
#################################################
#!/bin/ksh
export time=`date +%y%m%d`

/usr/bin/mkdir /nmonlog/nmon$time

mv /nmonlog/PRDWLCA2_$time_* /nmonlog/nmon$time

/usr/bin/tar -cvf nmon$time.tar nmon$time

at all.

Sample 1
" find /nmonlog -name 'PRDWLCA2_080926_*' -exec mv {} /nmonlog/nmon080926 \; "

Sample
find /nmonlog -name 'PRDWLCA2_$time_*' -exec mv {} /nmonlog/nmon$time \;

Just precede your "mv" command with "xargs -t" like this:

xargs -t mv . . . . .

The "xargs" command will break the "mv" command arguments into more manageable chunks.

Whoops.
Didn't read your script carefully.

Try it like this:

xargs -t -i mv /nmonlog/PRDWLCA2_$time_{} /nmonlog/nmon$time

I think this might work better.

cd /nmonlog/PRDWLCA2_$time_
ls | xargs -t -i mv {} /nmonlog/nmon$time

Alternatively, you could also set your ncargs parameter higher.

We had some issues with the ls command (arg list too long) and set ncargs from 6 (default) to 30 and the issue went away.

Not sure what AIX version you're using (we're on 5.3 TL07), but this should work.

Try smitty chgsys and look for "ARG/ENV list size in 4K byte blocks".

The max you can go to is 1024, but IBM recommended we change the parameter slowly upward until our problems with ls were resolved.

The change takes effect immediately and is consistent across all reboots.

Hope this helps.

Hi guys
Thanks for the feedback. I have test suggested way but still not sucesss.Using below line seems nothing being transfered from /nmonlog//PRDWLCA2_$time_{}to /nmonlog/nmon$time. its just hang on execution mode without returning to command prompt line even waited so long.

xargs -t -i mv /nmonlog/PRDWLCA2_$time_{} /nmonlog/nmon$time

When try below line its moving what ever files from /nmonlog to /nmonlog/nmon$time. I oly need to transfer PRDWLCA2_$time to /nmonlog/nmon$time but not sure why its transfer ALL files into /nmonlog/nmon$time.May need some touch on below lines
cd /nmonlog/PRDWLCA2_$time_
ls | xargs -t -i mv {} /nmonlog/nmon$time

Can anyone help me again? thanks guys

For future reference.

ls /nmonlog/ | grep 'PRDWLCA2_$time_' | xargs -t -i mv -f /nmonlog/{} /nmonlog/*<target_folder_name>*/
