How to run ls command case insensitive mode on Linux/Unix

To run the ls command in case-insensitive mode on a Linux or Unix system, you can use the -f option. This option tells the ls command to ignore the case of filenames and sort the output in a case-insensitive manner.

For example, to list the files in the current directory in a case-insensitive manner, you can use the following command:

ls -f

If you want to display the files in a case-insensitive manner and also show hidden files, you can use the -a option in combination with the -f option:

ls -af

Keep in mind that the -f option does not change the case of the filenames themselves, it only affects the way the ls command sorts the output. If you want to change the case of the filenames themselves, you can use the rename command or another tool such as exiv2 or perl.
