compare logfile content

Hi folks

I have some logfiles like this:

./2009_08_22_14_08_entire_backup_no_1.log
.
.
.
./2009_08_22_14_34_entire_backup_no_14.log

each one contains a timestamp from "date +'%s'"

now i need function which finds the logfile with the greatest number in it and returns (echos) the filename.

how can this be done?

I know this is not it..but a start..

Code:
function find_most_recent_entire_backup(){
    # read the logfile of the most recent entire_backup and 
    for f in `find ./ -type f -regex ".*entire.*.log" `; do
        timestamp=`grep [1,2,3,4,5,6,7,8,9,0] $f`
        echo $timestamp
    done
}


thank you already

ok time for me to learn awk...
any good tutorials on hand??

embaressing ..but i do not understand this oneliner at all Smilie

just running it at the prompt does not do it:

Code:
0:521:root@x301 /lvdata/backupdir [0]# find ./ -type f -regex ".*entire.*.log"
./2009_08_22_14_08_entire_backup_no_1.log
./2009_08_22_14_34_entire_backup_no_1.log
0:522:root@x301 /lvdata/backupdir [0]# for f in `find ./ -type f -regex ".*entire.*.log" `; do timestamp=`grep [1,2,3,4,5,6,7,8,9,0] $f`; echo $timestamp; done
1250942903
1250944466
0:523:root@x301 /lvdata/backupdir [0]# awk -F"./" '{d=substr($2,1,16);gsub("_","",d)}d>g{g=d;f=$0}END{print f}' file
awk: Kommandozeile:1: Fatal: Kann Datei 'file' nicht zum Lesen öffnen (Datei oder Verzeichnis nicht gefunden).
0:524:root@x301 /lvdata/backupdir [2]#

thank you

In that case:

Code:
find ./ -type f -regex ".*entire.*.log" |
awk -F"./" '{d=substr($2,1,16);gsub("_","",d)}d>g{g=d;f=$0}END{print f}'

Regards
