Edit/Delete Message

I haven't used it in a while, but look into logrotate:

http://linux.die.net/man/8/logrotate

You don't have to use it for the /var/log tree you can customize your profile to look at other files and delete those after they reach a certain size or age. Takes a bit of fooling with, but I used it to rotate and deprecate logs from an application I wrote so as to not overflow disk size but also keep the logs and offload them once they were swapped out.

Hi rtmistler,

Thanks for your reply.


using this code i can able to save the directory creation time , like this


this directory has to be deleted automatically after three months, is it possible with the help of this (Mar 16 18:48) date/time to calculate.

Hi all,

Is it possible using TimeStamp!!! concept

The find command is very good at finding files and directories of a specified age. I would try to use it as the basis for keeping track of files matching various age thresholds. Keeping track of file and directory age information is redundant, since the filesystem already does this, and is automatically up-to-date.

Hi theNbomr,

is it possible using "FIND" command to find the age of the directories in a particular path, if more that 2 months of the folder age means its automatically triggered mail to ADMIN, like that.....

Something like this, perhaps.
This assumes one month is 30 days. If that isn't good enough, you can play some games with the date command to find dates more precisely.

You can also look at running a script (possibly using find) from within cron, as this (cron scheduling) uses calendar mths.

HI chrism01,

Can you post any example, i am quite confused with find command, just now only started to reading the man page of find.

Hi all,


using this command i stored the details in one file which are created before 20 days.


Then using cut command

I separated the directory name which are created before 20 days alone like this,
now i want to send mail to admin these are the dir 20 days expired like that...how we can do that in scripting please guide me to do....

If you use '-ctime -20' in the argument to find, you will find files that are less than 20 days old (creation time; do you really mean modification time?). From your original post, it sounded like you wanted to find files that are older than a certain age. To do that, you would want to change the leading minus sign in the numeric argument to a plus sign.
Also, the use of cut to trim the leading directory name from files relies on the case that the files found are exactly 4 levels deep from the root. Better would be to use the built-in basename function. Example:
In your original post, you said you were looking for directories beyond 3 months old. To find directories with find, you would use the -type d option. I think it makes more sense to deal with files & directories, and this seems to be what you have adopted.

My example showed how to send the list of files to a user by e-mail:
--- rod.
