The command sort --ignore-case ${filename} is used to sort the contents of a file in ascending order, ignoring the case sensitivity of the text.

Here is a breakdown of the command:

• sort : This command is used to sort text lines in a file.
• --ignore-case : This option is used to make the sort command case-insensitive. It means that uppercase and lowercase letters will be considered the same when sorting.
• ${filename} : This is a placeholder for the actual filename or path of the file you want to sort. You need to replace ${filename} with the actual name or path of the file when using the command.

So, when you execute this command with the correct filename or path, it will read the contents of the file and sort them alphabetically, treating lowercase and uppercase letters as the same. The sorted output will be displayed on the screen or can be redirected to another file using the > or >> symbols.
