ll|awk '{print $6,$7} will give you dates stamp of a file. Not date "+format youwant" will give you date as you want. With these two things you should be bale to compare the file dates.

Also when comparing, you can use find . -newer option also. Man find for details.

Well short oof using "find" with the -mtime switch, you could use perl. Not exactly sure what you mean by "compare" but this line of perl will give you the modification time of the file. You can compare this with the output of the perl "time" function in which ever way you want.

perl -e 'print map { (stat $_)[9] } glob "filename"

p.s Thanks Merijn for the "map" lesson :)

wheely, that is missing quotes. And comparing to system date (or date script started), better be done with

# perl 'print map { -M } map { glob $_ } @ARGV' file ...

I want to do it using KSH and awk, I want to see if file is older than these many days to current date, I want to compress or delete the file.
Actual shell script would be helpful.

Thanks for all responses, I will assign points..
Thanks

The command your looking for is:

find -type f -mtime + -exec gzip {} \;

This will gzip files older then the number of days specified.
