Need another sort criterium for 'ls'
Hello all,

when I do a 'ls -l' in a certain Directory, I will get the following Output:

Code:
-rw-r--r--    1 area10  berol            237 Oct 28 16:12 copy_cubs291_84.txt
-rw-r--r--    1 area10  berol            238 Oct 28 17:28 copy_cubs291_85.txt
-rw-r--r--    1 area10  berol            210 Oct 28 12:25 exec_cubs291_71.txt
-rw-r--r--    1 area10  berol            210 Oct 28 12:30 exec_cubs291_72.txt
-rw-r--r--    1 area10  berol            210 Oct 28 12:30 exec_aubs291_71.txt

What I would like to have is an Output of filenames in the following order:

Code:
exec_aubs291_71.txt
exec_cubs291_71.txt
exec_cubs291_72.txt
exec_aubs291_71.txt
copy_cubs291_84.txt
copy_cubs291_85.txt

As you can see, I Need the sort for the element between the first word and the prefix.

How should I do this?

CU,

Hello API,

Could you please try following and let me know if this helps, I have checked this on bash.
Code:
ls *.txt | sort -t_ -k2,2

Output for above command was as follows.
Code:
exec_aabs291_71.txt
exec_aubs291_71.txt
copy_cubs291_84.txt
copy_cubs291_85.txt
exec_cubs291_71.txt
exec_cubs291_72.txt

Where I had created files exec_cubs291_72.txt, exec_cubs291_71.txt, exec_aubs291_71.txt, copy_cubs291_85.txt, copy_cubs291_84.txt, exec_aabs291_71.txt.

Thanks,
R. Singh

Thanks for you help.

But if I do it with your stated command, I will get the following Output:

Code:
-rw-r--r--    1 area10  berol            0 Nov  2 15:09 exec_aabs291_71.txt
-rw-r--r--    1 area10  berol            0 Nov  2 15:09 exec_aubs291_71.txt
-rw-r--r--    1 area10  berol            0 Nov  2 15:09 copy_cubs291_84.txt
-rw-r--r--    1 area10  berol            0 Nov  2 15:09 copy_cubs291_85.txt
-rw-r--r--    1 area10  berol            0 Nov  2 15:09 exec_cubs291_71.txt
-rw-r--r--    1 area10  berol            0 Nov  2 15:09 exec_cubs291_72.txt

For the sort criterum I will Need also the number after the ".ubs291_nn".

Unfortunately, your request is not clear. What exactly is "the element between the first word and the prefix"? Your two samples are somewhat contradictory as well, so your correct request can't be deduced from them either. Should you be after the two digit number ("nn"), I can't see that in your samples.

Ok. Sorry for my misleading Statements. I tried to explain it in words, but it seems not the best way to do this.

Once more.

I have These files within my Directory:
Code:
exec_aabs291_71.txt
exec_aubs291_71.txt
copy_cubs291_84.txt
copy_cubs291_85.txt
exec_cubs291_71.txt
exec_cubs291_72.txt

I would like to have an 'ls' where I will get the following order of Output:

Code:
exec_aabs291_71.txt
exec_aubs291_71.txt
exec_cubs291_71.txt
exec_cubs291_72.txt
copy_cubs291_84.txt
copy_cubs291_85.txt

So, in words: If you take one file - e.g. "exec_aabs291_71.txt" - the first sort-criteria should be the number "71", the second sort-criteria should be the text before "aabs291". And thats all.

Hopefully that will Point it out...

Well, then, try to extend RavinderSingh13's proposal:
Code:
ls *.txt | sort -t_ -k3,3 -k1,1

Hi.

You originally posted:
Code:
exec_aubs291_71.txt
exec_cubs291_71.txt
exec_cubs291_72.txt
exec_aubs291_71.txt
copy_cubs291_84.txt
copy_cubs291_85.txt

which has the "72" line out of place, which was confusing to me ... cheers, drl
