That script if fixed would only loop over the files in the current directory.

Try that and see if it does it.
Code:
find . -name "file*_*" | sort -t_ -k2 -g

Yea I want it to loop over the files in the current directory and then sort it so can I put
Code:
ls *_* | sort -t_ -k2 -g

into the loop? Or should I put it after

Neither! It was intended as a one-liner at the command line, on the current directory.
That's why I gave you the find command that would interact over every directory below the current.

That piece of shell script you posted in post #1 would not do what you want. At most, it would only loop through the files in the cwd, no directory, which ls *_* | sort -t_ -k2 -g does already on its own.

Last thing, what if the number after the _ is not the same? How would I sort based on the number before the _. I tried -k1 but that did not work.

Sorting using first field at position five numerically
Code:
ls *_* | sort -t_ -k1.5n

Last edited by Aia; 10-19-2014 at 01:54 AM.. Reason: removed the -r out of ls

Aia,
I don't understand how the ls -r option helps with this problem??? Why do you want to reverse the order of the filenames printed by ls when you're going to use sort to perform a numeric sort starting on the 5th character of the filenames?

totoro125,
Your requirements are extremely vague:
  1. Are you looking for files in a single directory, or in a directory hierarchy?
  2. If in a directory hierarchy, do you want the directory name included in the output, or do you just want to see the final component of the pathnames?
  3. Do the numbers you want to sort always contain exactly five digits (as in your examples)?
  4. Does the string before the digits you want to sort always consist of exactly four non-numeric characters (as in your examples)?
  5. Is the string before the digits you want to sort always file as in your examples, or does it vary from file to file?

Oh, did not noticed that. That's a mistype. It should be only ls like in previous posts. I edited it.
