If the file is sorted, and the data exceeds 24 hours, then the results will show only the maximum value for an hour on any day rather than the maximum for each hour on every day.

Code:
MAX=0
PREV_HR=25
while read time count
do
hour=${time:0:2}
if ( $PREV_HR -eq 25 )
then
      PREV_HR=$hour
fi
if ( $hour -ne $PREV_HR )
then
    echo $PREV_HR $MAX
    PREV_HR=$hour
    MAX=0
fi
if ( $count -gt $MAX )
then
    MAX=$count
fi
done
echo $PREV_HR $MAX

This module provides routines to format dates. They correspond to the libc routines. &strftime() supports a pretty good set of coversions -- more than most C libraries. strftime supports a pretty good set of conversions. The POSIX module has very similar functionality. You should consider using it instead if you do not have allergic reactions to system libraries. GENESIS
