Clear command help & alias
Hi Folks,

When I type clear on my unix prompt on mac terminal, it prints the help menu of a program instead of cleaning the contents of the screen.

Also, I have used the following alias command to setup some shortcuts, but soon after I logout and login, these shortcuts doesn't work.

Code:
alias l='ls -lh'

All helps appreciated.

with regards to the shortcuts are you setting these up in your .profile? if not and you are setting these at the command line, then they will disappear when you log off. you have to set them up in your .profile (or .bash_profile) (not big on Mac Unix). As for the clear solution not really sure on that, but did you try
Code:
tput clear

?

when I try
Code:
tput clear

it does exactly the same as clear command.

But, when I say just the clear command, it prints the same program's help menu. SmilieSmilieSmilie

check your aliases.

Code:
tput clear

is a system command. you might need to redefine the alias or at least check to see what it is set to. you might want to do a
Code:
man tput

so you can get an idea of what it can do for you

What's the output of

Code:
type clear

on your system?

And if clear is an alias for something, you may use
Code:
\clear

to escape the usage of that alias...
