minus-squareSuccessful_Try543@feddit.orglinkfedilinkarrow-up7arrow-down2·edit-26 days agoExactly, but that wasn’t the question.

minus-squareSuccessful_Try543@feddit.orglinkfedilinkarrow-up5arrow-down2·6 days agoThe question is: what happens when you give the command in the command line rm -rf ? rm -rf * or here rm -rf test are different commands.
minus-squareremon@ani.sociallinkfedilinkarrow-up3arrow-down1·edit-26 days agorm is the command, -rf are the flags and “test” is an required argument. So no, they are not different commands.
minus-squareSuccessful_Try543@feddit.orglinkfedilinkarrow-up6arrow-down2·6 days agoNo, the argument is not required, the command is valid. It’s intentional and a neat feature that rm -rf alone without a specified file does nothing. See e.g.: https://unix.stackexchange.com/a/553741
minus-squareremon@ani.sociallinkfedilinkarrow-up3arrow-down2·edit-26 days agoIt does nothing because you used the wrong syntax but also set the flag that suppresses the output of syntax errors … Imagine someone would asked “What does a toaster do?” I say “It toasts bread”. You come in with a picture of bread in a toaster and say “It does nothing”. I tell you “You have to press the button”. "You say “oh well, that wasn’t the question, a toaster with the button pressed is basically a different device!” Insert <Futurama not sure if trolling …> meme.

No, it does nothing.
$ mkdir test $ cd test ~/test$ touch 1 2 3 4 5 ~/test$ rm -rf ~/test$ ls 1 2 3 4 5If you dont specify the
-foption, which among other things tellsrmto be quiet, it throws an error:$ rm -r rm: missing operand Try 'rm --help' for more information.Because you’re using it on nothing.
$ mkdir test $ cd test ~/test$ touch 1 2 3 4 5 ~/test$ cd .. $ rm -rf test $ lsNo more test folder.
Exactly, but that wasn’t the question.

The question is:
rm -rf *or hererm -rf testare different commands.rm is the command, -rf are the flags and “test” is an required argument. So no, they are not different commands.
No, the argument is not required, the command is valid. It’s intentional and a neat feature that
rm -rfalone without a specified file does nothing.See e.g.: https://unix.stackexchange.com/a/553741
