Command help

Hi, I'm pretty brand new to Unix, and I was wondering if somebody could help understand some of the commands in Unix. I've been studying for my final exam, by doing last year's exam, and one of them has unix commands in it, and I'm not sure what they mean.

*Edit: My mistake, it's actually part of a make program.*

@rm -rf Suess.txt

I know that it's removing a txt file called Suess, but does anyone know what -rf or the @ symbol does?

Any help would be greatly appreciated!

Not sure of the @. Never seen that before. Have seen "\" which is used to ignore any aliases that have been set in .cshrc/.profile.

-r or -R is for recursive deletes normally used with directories. Same as rmdir
-f is used to "force" deletes.

For future reference and if you have access to a unix machine try using man command like "man commandName". It'll give you a little background on uses, flags, ...

Hope this helps!

@ is used to invoke a command from inside a makefile

sorry rm -r and rmdir are definitely not the same
