bash: pg: command not found

Hi...

I'm reading a book (Linux and Unix Shell Programming) and it tells me to do this:

Code:

$ pg var_test 
#!/bin/sh 
# var_test 
echo "First Name :\c" 
read name 
echo "Middle Name :\c" 
read middle 
echo "Last name :\c" 
read surname

when i try...i get this

Code:

$ pg var_test
bash: pg: command not found

i was wondering if this "pg" is a command specific only to straight-up Unix or certain types of Linux, and if so, what is the analogous command for FC3 ?

Any help is greatly appreciated. Thanks!!

pg is short for pager. You could use less instead.

Right, pg was written to overcome a "more" command limitation not allowing going backward on a file, and exists on Unix system V systems only I think.
Both modern "more" and the freeware "less" are providing this feature, making pg somewhat obsolete.
