Top Forums Shell Programming and Scripting command for deleting log files based on some condition Post 302156779 by Franklin52 on Wednesday 9th of January 2008 05:08:08 AM

Ok, some hints:

To find older files you can use the find command with the -mtime option.
To keep 5 files of the selection you can pipe the result to awk, to ignore the first 5 files you can do something like:

Code:
awk 'NR<6{next}{print}'

So it should look like:

Code:
find <options> | awk '....' | rm -f

If you have many files you can use xargs.

Code:
...| xargs rm -f

Check the man page of find for the options, search on this forum or Google for examples.


Regards

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
