tlmgr-update:tldr:52bbe
This command is used in a Unix-like system with the package manager tool called "tlmgr" (TeX Live Manager), which is used for managing packages in TeX Live, a popular typesetting system.
Here's a breakdown of the command components:
-
"sudo": It is a command used to execute another command with elevated privileges, typically as a superuser or administrator. Using "sudo" allows the user to perform system-level tasks.
-
"tlmgr": It refers to the command-line tool "tlmgr" (TeX Live Manager) used for managing TeX Live packages. It handles package installation, removal, and updates.
-
"update": This option instructs "tlmgr" to update the TeX Live distribution.
-
"--all": This option tells "tlmgr" to update all installed packages to the latest available version.
-
"--exclude ${package}": This option excludes a specific package from being updated. The placeholder "${package}" should be replaced with the name of the package to be excluded from the update. By specifying this option, the specified package will not be updated, even if a newer version is available.
Overall, this command updates all TeX Live packages, except for the one specified with "--exclude", and it should be executed with superuser privileges.
