A command to be typed into the computer directly
A file name
A directory name
A key to be pressed
Output from the computer
So, for example,
ls anydirectory [Enter]
means 'at the UNIX prompt, type ls followed by the name of some
directory, then press the key marked Enter'
Commands are not sent to the computer until
Note: Linux is case-sensitve, so
LS is not the same
ls. The same applies to filenames, so
MYFILE.TXT are three seperate files. Beware if
copying files to a PC, since DOS and Windows do not make this distinction.
