Change the display format for ls -l command in AIX


I am using AIX 5.3. In my server if I list the file , I got the below result in below format.

-rw-rw--w-   1 letapp1  staff             0 Jun  8 02:53 CC00030710.cntrl


But now I am seeing the one extra space between the "permission tab" and 'number of links" tab.

-rw-rw--w-    1 letapp1  staff             0 Jun  8 02:53 CC00030710.cntrl


Note:One extra space between "-rw-rw--w- " and "1".

Can anyone please let me know if we can able to modify the ls -l display format?

Thanks in advance,

ls -l | sed 's/ /  /'

Not sure wether it will change something or not, but could you try to add a backslash before your ls and see if you still get different output or not :
On Your AIX 5.3
\ls -l

On your other machine
\ls -l

Are the output still different ?

Has there been any patch upgrade on your OS?
Because the output what you are receiving is the standard output across all AIX 5.3

Hi Vidyadhar,

Yes, Batch upgrade went in our server. And after the upgrade only 'ls -l' command display format got changed. Many of our jobs are using the cut command with 'ls -l' command.

For example in our job we have the below command to get the size of the file.

ls -l test_cntl_file | cut -c30-43
-rw-rw-r--   1 letapp1  staff            28 Jun  4 16:00 test_cntl_file

For this we got the result "28".

But now since we got the one extra space between "-rw-rw-r--" and "1", we are getting the result for the above command as "f28".

To change this I need to identify all the jobs and needs to put a change. This will be a huge manual activity.

That why I am looking if I can able to remove the one extra space in 'ls -l' command result by modifying any server setup or something like that.

This is poor code, if the size is in the 5th column, you should use

ls -l test_cntl_file | awk '{print $5}'

(this code will not be sensitive to the number of space)

instead of
ls -l test_cntl_file | cut -c30-43

which will be sensitive to the number of space.

Yes, I agreed. But now if we cant modify the 'ls -l' display format, I need to modify all my scripts Smilie... Is there any way that we can change the dispaly format?

Why I am asking is in AIX with the same version itself, I saw in ls -l comand date field dispaly there is two different results in two different servers.

For example
-rw-rw-r--   1 letapp1  staff            60 Jun  9 02:00 passed_date.dat
-rw-rw-r--   1 letapp1  staff            60 Jun 09 02:00 passed_date.dat

So I hope there is some way we could achieve this. Please advice
