tlmgr-backup:tldr:23c48

This command is a command-line command using the "tlmgr" utility in the TeX Live software environment.

The purpose of this command is to backup and then clean (remove) selected packages in TeX Live.

Explanation of the command:

• "tlmgr": It is the command-line utility used for managing packages in TeX Live.
• "backup": This is an action keyword that tells tlmgr to perform a backup operation.
• "clean": This is another action keyword that tells tlmgr to clean (remove) the specified packages.
• "${package1 package2 ---}": This is the placeholder for the package names that need to be backed up and cleaned. You should replace "${package1 package2 ---}" with the actual names of the packages you want to backup and clean. Multiple package names can be provided separated by space.

For example, if you want to backup and clean the packages "package1" and "package2", you would replace "${package1 package2 ---}" with "package1 package2".
