I have a script which runs weekly on my crontab (see below) but would like to output results to file, how would I do this?

I tried including this option pointing to a txt file but didn't seem to work:

2>&1 >
#!/usr/bin/ksh
#Alert log tidy script

logDir="/bea_domains/config/AHE_CIT/logs"
tempDir="/tmp/alertLogArchive"
date=`date +%Y%m%d`
archiveDir="/bea_domains/config/AHE_CIT/logs/archive"

mkdir $tempDir

cd $logDir

find . -name "*alert.log*" -type f -mtime +30 -exec mv '{}' $tempDir \;

tar cvf - ${tempDir}/* | gzip > ${archiveDir}/alertlog_archive.${date}.tar.gz

rm -fr $tempDir

cd $archiveDir

find . -name "alertlog_archive*" -type f -mtime +60 -exec rm {} \;

Hi,

you could change yiur crontab entry like

* * * * * /path/to/script >/path/to/log 2>/path/to/errorlog

or you could add as the second/third lines to your script

exec 1>/path/to/log
exec 2>/path/to/errorlog

Of course you could combine both logs by using

2>&1 instead of 2>/path/to/errorlog

The output usually is in your mail que.
Try this:  0 * * * * ~/script.sh >/dev/null 2>&1

The second solution will give no output at all and you won't receive any email either. Is this what you desire?

Thx for the points anyway.

Note that

cmd 2>&1 >file

will not produce the same results as

cmd >file 2>&1
