Dear durden_tyler, Dear cfajohnson,

Thanks for your help. As I am starting to use shell script and UNIX system, It is hard for me to use the good word about programming language. I am really new about all of this, so I would say sorry for that.

Code:

Whether the shell is better than awk depends on the size of the file.

I've got a log file for each day of the week. Each log file (ex : command.log.2009-11-18) is about 20 or 50 Mo. As there is no web page to create report about this, my idea was to create a shell script with a read command to enter date or periode of the day, week or month and check which command were finished and print the date/time of each command.

I have also discovored that I've got the time on ms taken by the command. I will try to complete your help to make something very helpfull for me.

Code:

2009-10-30 14:50:05,544 [Command Thread-5] Command 266 INFO  saturne.service.command.manager.ExecutableCommand - COMMAND PROCESS FINISHED IN 11448 ms

Thanks to all for your help.

durden_tyler,

as the log file does record a lots of informations that I don't need I have to grep the log file to only found the string

Code:

COMMAND PROCESS FINISHED IN

to extract the info I am looking for. I supposed this is reason why the command that you given return error :

Code:

ksh[2]: ${c1##*-}/${c1:5:2}/${c1%%-*}: bad substitution

Anyway I will try to use all information aleady given to make my need to work
