 SYNTAX

       alias  new_command  transformed-command

 FUNCTION

       alias is not a stand-alone command but

       rather a shorthand facility within csh.

       The alias mechanism is normally used to create a 

       short name for long commands with many arguments.

       alias is also used for creating another name

       (hopefully simpler or easier to remember) for the 

       existing commands.

 By using the alias mechanism, let us

 transform the command  who | wc -l into

 the command howmany to see how many users

 are logged on.  Note that because the transformed 

 expression contains spaces, it needs to be 

 enclosed in single quotes:  '....'.

 $PROMPT$

 That is correct!

 You've got it on the 2nd try.

 Good, you understand the concept.

 Try alias howmany 'who | wc -l'

 Please enter alias howmany 'who | wc -l'

 I guess I must type this for you:

 $PROMPT$

FORGET1

 $PROMPT$alias howmany 'who | wc -l'  

 Observe the result on the terminal. 

 $PROMPT$

  Let us use the new aliased command howmany

  to see how many users are on your system!

 $PROMPT$

 That is correct!

 You've got it on the 2nd try.

 Good, you understand the concept.

 Please try howmany

 Please enter howmany

 $PROMPT$howmany

 $PROMPT$

 The result produced using an alias under  csh 

 is the same as using  who | wc -l under  sh .
