get last 5 minutes' log from log file?
Hi all, I have tried to figure out a way to automatically get the last 5 minutes' log content from log file, at first, my thoughts like this,
sed -n "/ $(date +\%R -d "-5 min")/,$"p syslog > newfile,
but quickly I found it did not work, say I have a syslog file as following,
Jul 19 18:15:23 ........
Jul 19 18:15:28 ........
Jul 19 18:17:11 ........
Jul 19 18:18:11 ........
if the script run at 18:21,18:21 minus 5minutes is 18:16,since there is no "18:16" in logfile, sed will find no match, thus there will be nothing in the newfile", although actually it should have!
I know there will be solution around the corner, but how? Thanks!

I need to know if anyone can assist me on how to grab the last (we'll just say "x" minutes) of a log file. How do you tell the grep command without specifying an exact window of time? (So relative instead of absolute.)
Thanks,
