Script not running correctly
Hi all,

My script below was working fine till I changed the LOGFILE path (which originally points to a file within the same folder of the script for testing)

Only the event.log file path is changed, the rest are still within the current folder.

Before the change, running the script works. After the change, from the "sed" commands onwards, it doesn't seem to trigger.

I separated the 'sed' part to another script, and ran that on its own, therefore, the commands work.

But somehow putting it together seems to give me a major headache.

Need help quickly.

Thanks.

Code:
#!/bin/sh
integer CURCOUNT
LOGFILE=/var/opt/resmon/log/event.log

#Compare current count line with old count line in oldcount.txt
OLDCOUNT=`cat oldcount.txt | awk '{print $1}'`

CURCOUNT=`wc -l /var/opt/resmon/log/event.log | awk '{print $1}`

if [ "$CURCOUNT" = "$OLDCOUNT" ]; then
        echo "NO Change"
        exit
else

NEWLINES=`expr $CURCOUNT - $OLDCOUNT`

# Read and output new lines to diffline.txt
STARTLINE=`expr $OLDCOUNT + 1`
LASTLINE=$CURCOUNT

awk -v SL=$STARTLINE -v LL=$LASTLINE '
((NR >=SL) && (NR <=LL)) {print  $0}' /var/opt/resmon/log/event.log > diffline.txt

#Updates oldcount.txt with latest value
echo $CURCOUNT > oldcount.txt
exit
fi

sed -ne '/^---/p' -e '/Severity............: CRITICAL/,/^Description of Error/p' -e '/Severity............: MAJORWARNING/,/^Description of Er
ror/p' diffline.txt | sed -ne '/^Severity/p' -e '/^Summary/,/^Description of Error/p' | sed '/^Description/d' | sed '/^$/d' | sed 's/^[ \t]*/

sed -n '

NAME

       script - make record of a terminal session

SYNOPSIS

       script [-a] [filename]

DESCRIPTION

       The  script  utility  makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the
       record is saved in the file typescript. See WARNINGS.

       The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends
       when the forked shell exits or when Control-d is typed.

OPTIONS

       The following option is supported:

       -a    Appends the session record to filename, rather than overwriting it.

NOTES

       script places everything that appears on the screen in filename, including prompts.

WARNINGS

       script  can  pose  a  security risk when used in directories that are writable by other users (for example, /tmp), especially when run by a
       privileged user, that is, root. Be sure that typescript is not a link before running script.
