Grepping the last 30 minutes of a log file...
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,
Jon

nnusage
NNUSAGE(1m) NNUSAGE(1m)
NAME
nnusage - display nn usage statistics
SYNOPSIS
nnusage [ -at ]
DESCRIPTION
nnusage will extract the usage entries from the log file and calculate the total usage time for the current user, or for all nn users if -a
is specified.
When -t is used with the -a option, nnusage will list the users ordered after the total usage time. Otherwise, the output will be sorted
according to user names.
Since it is possible to suspend nn, or leave the terminal while nn is active, nn tries to be intelligent when it calculates the usage time
so it will truly report the actual time spent on news reading.
FILES
../Log The log file
SEE ALSO
nn(1), nncheck(1), nngoback(1), nngrep(1), nntidy(1)
nnacct(1m), nnadmin(1M), nnquery(1M), nnmaster(8)
NOTES
If nn is compiled with ACCOUNTING turned on, then calls to nnusage are converted into equivalent calls to nnacct.
The nn package must have been compiled with the STATISTICS option turned on to produce the usage entries in the log file.
Only nn sessions longer than 5 minutes are registered in the log file.
