How can I list (ls) the 5 last modified files in a directory?

Question

I know ls -t will list all files by modified time. But how can I limit these results to only the last n files?

Answer 1

Use tail command:

ls -t | tail -n 5

Answer 2

ls -t list files by creation time not last modified time. Use ls -ltc if you want to list files by last modified time from last to first(top to bottom). Thus to list the last n: ls -ltc | head ${n}

Answer 3

Try using head or tail. If you want the 5 most-recently modified files:

ls -1t | head -5

The -1 (that's a one) says one file per line and the head says take the first 5 entries.

If you want the last 5 try

ls -1t | tail -5

Answer 4

By default ls -t sorts output from newest to oldest, so the combination of commands to use depends in which direction you want your output to be ordered.

For the newest 5 files ordered from newest to oldest, use head to take the first 5 lines of output:

ls -t | head -n 5

For the newest 5 files ordered from oldest to newest, use the -r switch to reverse ls's sort order, and use tail to take the last 5 lines of output:

ls -tr | tail -n 5

Answer 5

The accepted answer lists only the filenames, but to get the top 5 files one can also use:

ls -lht | head -6

where:

-l outputs in a list format

-h makes output human readable (i.e. file sizes appear in kb, mb, etc.)

-t sorts output by placing most recently modified file first

head -6 will show 5 files because ls prints the block size in the first line of output.

I think this is a slightly more elegant and possibly more useful approach.

Example output:
