Listing files by name alphanumeric order is, after all, the default. You can choose the ls no details or ls -l lots of details to determine your view. Pipe the output of ls to the more command if you want to review your listing a screenful at a time. To reverse the listing of files by name, add the -r reverse option. This will be like turning the normal listing upside down. There is, however, a command option that can list files by extension.

If you add the -X option, ls will sort files by name within each extension category. For example, it will list files without extensions first in alphanumeric order followed by files with extensions like. By default, the ls command will show both files and directories. If you want to list only directories, you can use the -d option.

You will get a listing like this one:. If you want to list files in size order, add the -S option. Note, however, that this won't actually show you the sizes along with other file details unless you also add the -l long listing option. When listing files by size, it's generally helpful to see that the command is doing what you asked. The -l flag tells the ls command to print the returned output in a long list format. By default, the ls command lists files in ascending order.

To reverse the sorting order, pass the -r flag to the ls -l command, like this: ls -lr. Passing the -r flag to the ls -l command applies to other examples in this tutorial.

Instead of sorting files alphabetically, you may want to sort files by file size. Sorting files by size is handy when prioritizing seeing either the smallest or largest files in a list. To sort files by size, pass the -S flag to tell the ls command to sort the list of files by file size. Run the command below to list files ls sorted by file size in a long list format -lS. Below, you can see the command sorted the files by size in descending order biggest to smallest in size.

To reverse the sorting order smallest to biggest , add the -r flag, like this: ls -lSr. Moving forward from sorting files by size, you might encounter a use case where you need to sort files by the time they were modified. For example, you forgot the name of the file you created, and you only remember the time you last modified the file. Run the command below where the -t parameter tells the ls command to sort the files by modification time.

I added to my. So the answer to the question is use ls -X : — Andrew. Not what was asked for — Sridhar Sarnobat. SridharSarnobat I personnally think his answers was totally on topic. And following his suggestion, I have added lx as a bash alias for having ls sorting by file extension and then name: approximately the exact label for this question.

Does it group directories and files separately? I think that was what I was looking for. ClareMacrae "know" would not be the correct term :- I could have used "this" instead of "his", you're right — Stephane Rolland. Sign up or log in Sign up using Google. Sign up using Facebook.

Though ls provides some sorting options as mentioned above, it does not have the ability to sort by many of the other file attributes, such as owner name or group name.

But you can still sort by these fields by piping the output through to the sort command. In order to use the sort command to sort the output of ls , you should make sure that the field that you want to sort by is displayed by the ls command. The -l option prints out the long listing format which works for most cases. This will print out the attributes in a column mode. Now find the field or attribute that you want to sort by and its column or field number.
