Yeap, I saw it after all. Thanks

Hi guys,

I'm learning python and perl and i was trying to run from python a perl script using the subprocess module.
I have an issue that i don't understand regarding this.

I run this code:...

For automating stuff like : backup logs, search for new warnings, verify files sequences etc i have most of the scripts made in bash.

I would like to go further in getting more knowledge, involvin...

Hi guys,

I am currently working as a system administration engineer, administering telecom applications on linux/unix platforms.

I want to learn new things and improve the ones that i have and...

Try:

df -h | awk ' $1 ~ /rootvg/ {print $2, $5}' >> yourfile.txt

Well it is quite a simple script. But i'm also a begineer and I will explain it for you:

- First we declare a variable VAR that computes the number of processes running from the process listing(...

It looks ok. One thing:
After initiating the commands to stop the database, be sure to take the time until it has stopped. Sometimes it takes a little before the processes are killed and cleared.
...

Your script should look something like this :

#!/bin/bash

#Get the number of processes containing etl running
VAR=`ps -ef | grep 'etl' | grep -v grep | wc -l`

#Verify if VAR >= 1
if [ $VAR...

You are right, thanks. I am also in a learning phase!:)

are you using AWK for this?

if so you need to pass the variable into awk :

awk -v var="$wordToMatch" ' $0 ~ /var/ {printf("%s", "OK")}

Hope this helps you.

awk 'gsub(/.../,"&\n",$2) {print "o/p:";print $2}'

This will give you the output required. It's only available in this case.

Or this
awk 'BEGIN {print "o/p:"} gsub(/.../,"&\n",$2) {print $2}'

ps - ef - lists processes
grep test - print output lines that contain "test"
grep -v grep - excludes the "grep test" process you ran earlier from the list

For awk i think you can use printf ("%s", $0) instead of print $0

Hope it helps.

grep -i "exception" /ops/opt/aaa/bvg.log | mail -s "Exception occured" email@address.com


You can start from here.
Put in a script, add more logic to it then put it in a cron job to run every...

The below will tell you if the files are different or not
cmp -s file1.txt file2.txt; echo $? | xargs -I var bash -c 'if [ var -gt 0 ];then echo "Files are different"; else echo "Files are the...

Do you want to print the exact difference? or the lines that are different?

Look at the small script below. Hope it helps


#!/bin/bash
#Date
#Author
#Purpose : Alert on failed count > 0
#Usage : ./alertonfail.sh <file>

#File with the failed count
FILE=$1
...

This is what i came with. If i correctly understood your question.

You have a file like :
PROCESS1 DATE=130813 TIME=130503 BATCHNO=0000000014
PROCESS1 DATE=130813 TIME=130503...
