Actually this reminds me, what is the deal with tar command recommendations to use or not use dash? I know GNU tar accepts both (e.g.)
tar xvf file.tar
andtar -xvf file.tar
, but at some points people were like "NO! Don't use the dash! It's going to maybe cause issues somewhere, who knows!" and I was like "OK". Something to do with people up designing the Unix specs?I didn't even know the dash was optional. I guess you learn something new everyday.
I still use it though. Its how I learned it all those years ago and its ingrained as muscle memory when typing the command.
idk if it's optional why bother typing it
personally, it is a little easier to read, especially in a script. and its more consistent with other commands
No idea, but with tar I never use dashes. Just tar xf away.
POSIX. POSIX didn't get designed but documented behaviour that was portable between different UNIX flavours and was then declared a standard.
If you're annoyed by it just consider the
xvf
intar xvf
to be a subcommand aspull
is ingit pull
. Tar simply has a fancy subcommand syntax. At least it's notdd
.
