Shell script Help

I have tried searching and can't find anything that is on this topic. My provider deletes all logs after one day to conserve space. Here is what I am trying to do:

Make a shell or PHP script that will:

1) Copy a file from one directory to another. It is a log file, so a shell script would work better.

2) Rename the file to include todays date. This is essential because I need to no overwrite it the next day.

3) gzip the file to save space.

I want to save stats for atleast a week so I can go on vacation and still access the raw logs.

Any help would be appreciated. If you can just point me to the right reference, that would even help.

I just wrote this up. I tested it on my system (paths still in the code) and it works fine as long as you only do one file at a time (you can't use *).

usage:
filename [source file [destination directory]]

#!/bin/sh

if [ $# -gt 0 ]; then
  source_file=$1
else
  source_file=/home/maxalbert.com/logs/access_log
fi

if [ $# -gt 1 ]; then
  dest_dir=$2
else
  dest_dir=/home/maxalbert.com/test
fi

day_stamp=`date +%Y_%m_%d`
filename=`echo $source_file | awk -F/ '{print $NF}'`

dest_dir="$dest_dir/$day_stamp/"

if [ ! -d $dest_dir ]; then
  mkdir -p $dest_dir
fi

cp $source_file "$dest_dir/$filename"

exit 0;

Make sure your provide allows cron jobs so that you can schedule the task.

BTW, the way the script is configured above, it will copy the file(access_log)
FROM: /home/maxalbert.com/logs/access_log
TO: /home/maxalbert.com/test/YYYY_MM_DD/access_log

You can pass the FROM and TO as arguements to the shell script. And/Or configure the script to use a certain file and path for default values.

CRON is probably the best way to do it (as FunkyJ mentioned). Try to run it just before they prun the file.
