mount:tldr:ab178

This command is used to mount a file system from a device file (such as a partition on a hard drive or an external USB device) to a designated target directory in the file system hierarchy. Here is a breakdown of the command:

• mount: This is the command to mount a file system.
• -o uid=${user_id},gid=${group_id}: The -o option is used to specify mount options. In this case, it sets the user ID (uid) and group ID (gid) for the mounted file system. ${user_id} and ${group_id} are placeholders for actual numeric IDs of the desired user and group, respectively.
• ${path-to-device_file}: This is the path to the device file that represents the file system you want to mount. It could be something like /dev/sdb1 for a specific partition on a secondary hard drive.
• ${path-to-target_directory}: This is the path to the directory where you want the file system to be mounted. It could be an existing directory or a new directory you create as the mount point.

When this command is executed, the specified device file will be mounted to the target directory, and the file system will become accessible at that location in the directory tree.
