Once again:

Read shell scripting tutorials http://tldp.org/LDP/abs/html/
Understand what they're saying
Apply basic, common-sense troubleshooting skills.

These things apply to ALL problems, not just shell scripts. Walk through things one step at a time, and figure out what's wrong. Again, you have been given the solution several times. Also, have you bothered to read the sarg man page? Perhaps look at the "-o" option, that TELLS SARG WHERE TO WRITE THE REPORT, which you haven't done yet.

Nice one, Cedrik.

For some reason, this conversation is starting to remind me of the first episode of Red Dwarf.

It's redirected to a file, Dave. Stdout is redirected to a file. Stderr is redirected to a file. All output is redirected to a file. Everything is redirected to a file, Dave.
(Sorry, couldn't resist)

Hi TBOne,

Today I tried this script to generate weekly report:

Quote:

#!/bin/bash
LOG_FILES=
if [ -s /var/log/squid/access.log.2.gz ]; then
LOG_FILES="-l /var/log/squid/access.log.2.gz"
fi
if [ -s /var/log/squid/access.log.1.gz ]; then
LOG_FILES="-l /var/log/squid/access.log.1.gz"
fi
if [ -s /var/log/squid/access.log ]; then
LOG_FILES="-l /var/log/squid/access.log"
fi

# Get yesterday's date
YESTERDAY=$(date --date "1 days ago" +%d/%m/%Y)

# Get one week ago date
WEEKAGO=$(date --date "7 days ago" +%d/%m/%Y)

exec /usr/bin/sarg \
$LOG_FILES \
-o /var/www/sarg/weekly \
-d $WEEKAGO-$YESTERDAY &>/dev/null
exit 0

And I got this error:

Now it shows that 'buffer overflow detected'. What could be the solution to this?

This may be a bug in sarg. Are you using the latest version? It could also be caused by something being wrong with the input data, but in any case crashing as a way of informing the user of invalid input is generally not considered a good programming practice.

How large is your log file? If I were you, I would also look at the sarg.conf file and try to play with the settings a bit.

Hi millgates,

Quote:

The version of sarg I'm using is sarg-2.2.3.1 Jan-02-2007.

Quote:

If you're asing about access.log then it keeps on rotating, so size of log file keeps on varying.

And here I'm attaching my sarg.conf file. Please look into the configuration file, the changes I have made if it is correct...

So you're using five year old software? The latest version is 2.3.1, and if you read the changelogs on the sarg site, you'd see that it's been patched numerous times, to address crashing. Run the latest version.

The sarg config isn't getting read, since the program is crashing, so there's not much to look at there. Update your software.

Thanks TBOne, I got it.
