Shell Programming and Scripting

Hello Folks,

i have written a script to nullify the log files in my dev environment but the log files are not getting nullified.Please find below my script and also thank you all in advance for your help.


find /app -size +100000 -xdev -exec du -k {} \; 2>/dev/null | sort -nr |ls -1dF /app/apal/obl/obcl*/logs/apa_[0-9]*.log > /tmp/RR0
cat RR0 | cut -d"/" -f1-5 > /tmp/RR1

for RR2 in 'cat /tmp/RR1'
do
cd {$RR2}
echo 'pwd'
if[ -f apache_[0-9]*.log ]
> apa_[0-9]*.log
fi



let me knw if u want some other detail in this regard?

You could:

Code:

find /app -size +100000 -iname apa\*.log 2>/dev/null | xargs -t -iF echo rm 'F' 2>&1 \
| awk '{print $2}' | xargs -iF echo touch 'F'

...but that misses out on setting ownership and DAC rights, so you could:

Code:

find /app -size +100000 -iname apa\*.log 2>/dev/null | while read FILENAME; do $>"$FILENAME"; done

...however if an application keeps the log open you would have to stop it, zap the log then start it again..

Code:

# ...and that's why using logrotate often works better than reinventing the wheel... ;-p

Logrotate can act on log size, run single-shot or cronjobbed, has pre/postscripts to stop/start services, et cetera.

what is the iname option stands in the find command?

is it inode no...?



i have given a try of the above find cmd which u have given,
but it doesn't display any list of log files?

find /app -size +100000 -iname /app/apache/oblix/obcls*/logs/apache_[0-9]*.log 2>/dev/null


what this above cmd will do?


Thanks in advance
