Vajiramani

what exactly are you trying to achieve here

you can check this way

-rw-rw-r-- 1 kanth kanth 0 Feb 24 11:33 created_file
-rw-rw-r-- 1 kanth kanth 0 Feb 24 11:33 modified_file


suppose you have two file as above...


take 6,7 and 8th column and compare it by using "if" conditions

create=`ls -lrt created_file | awk '{print $6$7$8}'`
modify=`ls -lrt modified_file |awk '{print $6$7$8}'`

U can use find command .
it has various options
-mtime 3 --to find files modified exactly 3days ago
-mtime +3 --to find files modified more than 3days
-mtime -3 --to find files modified within 3days

similarly
u have
-atime,-ctime and -newer etc

Thank u its help full.

Actually what i want to trying to do is getting some parameters as command line arguments while running a shell script and use it. Then with this i need to delete files from a directory if its exceeding the count 7.

The above command will delete wat ever the specified date interval. Its also in away good but i need exactly 7 files in the directory even if i don't generate one file for a day.

Now i need how to get command line parameters to be used int he script

Thanks again

Call the scpt with three arguments
If you pass more than 9 arguments, then use brace
If your string argument contain spaces then use double quotes
