listing up files in a list file in 'last modified files last' order

  • 772

If I do ls -ltrd * I can list the files or directories sorted in the modified time order (recent ones at the end, because of the r option). Now I have a file containing list of this files or directories like this (by the way this list contains only files). Suppose this is the file list.txt.

I want to list up these files in reverse modified time order. How should I do it? I have tried

ls -ltrd < cat list

but it gives me

bash: cat: No such file or directory

or when I tried

ls -ltrd < `cat list.txt`

it gives me

bash: `cat list.txt`: ambiguous redirect

How should I do it?

command-line

    I found this piping-the-contents-of-a-file-to-ls and here is my answer:

    xargs ls -ltrd < list.txt
