Hi all,

i have a simple question that i want to find out the 30 minutes older files and delete those files from the particular location(Folder)

Generally for this purpose used to retreive the files with "atime" command

For example: find and delete the 2 days older log files use this below command

find $HOME/Log -type f -name "*.log" -atime+2 -exec {} \;

But how can use for 30 min older files...?

Suggession are apprciated.

Thanks and Regards,
MPS

Use *min for minutes.

find $HOME/Log -type f -name "*.log" -amin +30 -exec ls {} \;

If the OP is on Linux or has GNU find -amin works

Otherwise try:

#!/bin/ksh
# filetimes
filetime()
{
    perl  -e '
          $mtime = (stat $ARGV[0])[9];
          print $mtime
         ' $1
}
now=$(date +%s)
limit=$(( $now - 1800 ))  # one half hour ago.

find /path/to/files -type f |\
while read filename 
do
	dt=$(filetime  $filename)
	if [[ $dt -lt $limit ]] ; then
   		rm -f $filename  # delete ALL files older then 30 minutes
   	fi
done
