I am trying to understand linux and working through some tutorials. One states that I can copy files to the current directory by using a cp -a command with a relative pathname such as



cp -a ../somedir/. 


It fails each time I run it. Is the syntax incorrect?

I tried the man page, but it didn't seem to find anything that answers my question.

cp -a ../somedir/. is wrong. The general syntax is



cp source target


You only specified one argument. To copy something to current directory, you can run



cp ../somedir .


Note the space before the dot. . is shorthand for current directory. .. is shorthand for parent directory.
