chown:tldr:1214d

The command "chown ${user} ${filename_or_directory}" is used to change the ownership of a file or directory in a Linux or Unix-based operating system. Here's a breakdown of each component:

• "chown": This is short for "change owner" and it is a command-line utility that allows you to modify the ownership of files and directories.
• "${user}": This is a placeholder for the desired username or user ID (UID) you want to assign as the new owner. You need to replace "${user}" with the actual username or UID you want to use.
• "${filename_or_directory}": This is a placeholder for the file or directory you want to change the ownership of. You need to replace "${filename_or_directory}" with the name or path of the specific file or directory you want to modify.

By combining these components, the command allows you to change the owner of a file or directory to a specific user.
