Shell Programming and Scripting

Yes...It is working.. Thanks a lot...!!

Hi,

Am facing some issues with perl.

I cant use perl in our env..

Can you please suggest any other solution??

What could you use?

i think i was wrong...sorry.

@Kattoor
Please post your exact Operating System and version or at least the output from "uname -a". It is clear that it is not mainstream Linux with extended functionality in the "date" command.
Is this an automated task which checks at fixed time intervals, or an "on demand" task of some sort? If is is an automated task the solution is fairly simple providing that you have access to cron. If it is an "on demand" task will there be one user or multiple users?
A an earlier poster asked, how accurate does the 4 hours need to be?

Sorry for the confusion.

The version I am using is HP-UX BOX B.11.11 U 9000/800
In my env perl is working fine, but I am not supposed to use 'perl' in our script as I am not sure the perl will work in our live env.

I need to check the 4 hours condition in one of my script that will be invoked using crone. I may have many files in my directory and I need to check out whether any files has been created 4 hours ago.

I hope now you are clear with the requirement.

I don't know how "date" and "ls" work on HP-UX, but the solution I offered is at least a clue.

Code:

ls -l --time-style=long-iso

this will produce a list of lines in which the create time of files appear in a form of "2010-04-15 16:27"(on column 6 and 7 in my case), which can be compared with that produced by

Code:

date +"%Y-%m-%d %R" --date="240 minutes ago"

You may just modify the one liner and get it work for your situation.

I have modified the one liner a little bit. I test it on RHEL and Cygwin, and it works as expected:

Code:

ls -l --time-style=long-iso | awk ' BEGIN { "date +\"%Y-%m-%d %R\" --date=\"240 minutes ago\"" | getline minutes } $6" "$7 >= minutes { print $NF } '

Good luck.
