script for the error logs from multiple directories

[Grayh]

I have the following directories under the dir /var/MS/YER

ROW21_M2_HP1_20080809.163321_FTS_101/
ROW23_M2_HP1_20080809.164402_FTS_101/
ROW24_M2_HP1_20080809.165257_FTS_101/
ROW28_NO_HP1_20080809.171014_FTS_101/
ROW02_NO_HP1_20080809.171249_FTS_101/
ROW03_NO_HP1_20080809.172207_FTS_101/
ROW05_NO_HP1_20080809.173117_FTS_101/
ROW06_NO_HP1_20080809.173942_FTS_101/
ROW09_NO_HP1_20080809.174756_FTS_101/
ROW12_NO_HP1_20080809.175616_FTS_101/
ROW15_NO_HP1_20080809.180438_FTS_101/

I have a .log file in each of the directories above..

Is there a way or script by which I can grep for the string "failed" & the no. of failures(count) from all of the logs in the directories.

plz help

grep failed /var/MS/YER/ROW*101/*.log | wc -l

Hi:

If you want the actual matching lines along with a count of the lines matched at the end, you could use:

# cat ./filter
#!/usr/bin/sh
LOG=/tmp/$(basename $0).$$
trap 'rm ${LOG}' EXIT
grep failed /var/MS/YER/ROW*101/*.log > ${LOG}
cat ${LOG}
wc -l < ${LOG}
exit

...run as:

# ./filter

By the way, please evaulate the answers you received to your previous post, too :-)

Thanks JRF,

I am about to run this script now... I have a small doubt...

what does the following line do in the script

trap 'rm ${LOG}' EXIT

Hi (again):

> what does the following line do in the script

trap 'rm ${LOG}' EXIT

This simply removes the file named by ${LOG} when the script exits. It's a convenient way to perform simple cleanup code, automatically, without explicitly calling a function or in-lining code, from any point in your script, when it exits.
