The command "tmsu tags ${*-mp3}" is a command that uses the "tmsu" tool to display the tags of MP3 files. Let's break it down:
-
"tmsu": This is the name of the tool or command-line application we are using. "tmsu" is a file tagging tool that allows users to assign tags to files for easy organization and retrieval.
-
"tags": This is a subcommand of "tmsu" that specifies we want to list the tags associated with files.
-
"${-mp3}": This part is called a shell variable expansion. The "" symbol is a wildcard that matches any characters. So, ${*-mp3} essentially means "any characters followed by '-mp3'".
By using this variable expansion, we instruct the command to display tags only for those files that end with "-mp3". This allows us to filter and display tags specifically for MP3 files.
Overall, this command lists the tags of MP3 files using the "tmsu" tool, making it easier to manage and organize large collections of music files.
