how to extract paragraphs from file in BASH script followed by prefix ! , !! and !!!
I]hi all
i am in confusion since last 2 days
i posted thraed yesterday and some friends did help but still i couldnt get solution to my problem
let it be very clear
i have a long log file of alkatel switch and i have to seperate the minor major and critical alarms shown by ! , !! and !!! respectively
how wil i extract these paragraphs of alarms in respective alarm file??
i need to extract this log on the basis of prefix ! , !! , !!!
i am using the code to take input from file into script as
Code:
#!/bin/bash
alarm= `cat ~/alkatel.txt`
echo $alarm | while read line
do
{
echo $line
}done
i want to see this code in bash only not in perl and any othe language please do me this favor
rm old alarm* files
will read an input file called alarms
put any beginning undefined lines into alarm
read thru the file, and based on ! or !! or !!! determine output file
write line to case'd filename
Note: once an alarm file is set, everything will be written there until a new alarm file is calculated.
#! /bin/bash
rm alarm alarm1 alarm2 alarm3
al_fl="alarm"
while read alt
do
al_pr=$(echo $alt | cut -d" " -f1)
case "$al_pr"
in
'!') al_fl="alarm1";;
'!!') al_fl="alarm2";;
'!!!') al_fl="alarm3";;
*) ;;
esac
# echo "$al_pr" "$al_fl"
echo "$alt">>"$al_fl"
done < alarms
