Command and command-line-interface (which is the tooltip hint for command-line) aren't synonyms.
A command might be a shell build-in or a program-execution, which means parameters, arguments and such.
find /home -type f -name bar -execdir echo {} ";"
is a command, where find is the program name. Inside the program there is another command executed, named 'echo', and since it is called from find, not from the shell itself, is the external program, not the shell build-in.
There are lots of places, where a command is issued without shell.
If you want a sweet little command executed, you may need the syntax and some options explained, but whether it is called from find, from a command-line or gedit is another topic. It can be meaningful, but it needn't.
shell-scripting
is appropriate, and for some "how do I do foo in bash" perhapsbash
is appropriate. But if it's just something like Torrent client for the command-line? then the fact that you're running it through a shell is really irrelevant.
