so if i'm getting it right, you have to delete all .dat files in that folder which are 7 days old? (7 days or less or 7 days or more)??

Code:

find /var/oracle/etl/incoming '*.dat' -mtime +7 -exec rm {} \;

A shell script is essentially a series of commands. In this case you only need one command, as already given:

With correction and safety:

Code:

find /var/oracle/etl/incoming -name '*.dat' -mtime +7 -exec echo rm {} \;

Remove the echo when you are confident it is going to remove the files you want to remove.

Sure sounds like homework to me. What have you done to find a solution to the problem? Other than to post here.

We will aid you when you help yourself to a solution. Provide us with what you have attempted and then maybe someone will be able to assist. To spoon feed member answers for homework helps no one, especially the requester.

As the LQ Rules state;

Do not expect LQ members to do your homework - you will learn much more by doing it yourself.

FYI: I suggest that you look at 'How to Ask Questions the Smart Way' so in the future your queries provide information that will aid us in diagnosis of the problem.  

For scripting I suggest that you look at 4,5 & 6 below.

Just a few links to aid you to gaining some understanding;

  1 Linux Documentation Project 
2 Rute Tutorial & Exposition 
3 Linux Command Guide  
4 Bash Beginners Guide 
5 Bash Reference Manual 
6 Advanced Bash-Scripting Guide 
7 Linux Newbie Admin Guide

If the issue is solved, mark the thread as solved.

I'm with onebuck on the homework issue but a solution had already been offered

Hi,

Too many members just shoot answers without considering consequences for the OP. Sure, answered but did the poster learn anything other than copy & paste?

As a member I would like to see others think about shot-gunning solutions. Would you want someone that could perform, possibly stumble while in training to learn or someone that gets the answer then graduates and then fails? I would not hire the latter!

There's a time for spoon feeding and a time to address a posters attempt at the tasks. Throwing out answers helps no one, not even the member who already knows the answer. Try to model your answer to help the poster to understand not flat out doing the task(s).

This LQR is simple but justifiable, reasonable and should be the controlling factor when addressing homework so the poster can learn. We may need to assist yet not do it.

In support of what Gary said, I believe the old adage about giving a fish to a man applies:

Give a man a fish and he will eat for a day.
Teach a man to fish and he will steal all of the big ones in your pond.

Just following the link there for view replies points me back to LQ.
