where are alias stored

[vickey_20]

When I issue 'alias' command it shows me all alias set. But where are these commands actually stored???

Check the contents of .bash_profile file in your home folder.

It depends a bit. Any one of these can store aliasses:

/etc/profile gets sourced during a login session
~/.bashrc gets sourced during non-login session
and ~/.bash_profile always gets sourced

but what if I do something like this on my pc

alias c=clear

on the prompt ,this short cut is available only till the time I work. Where is it stored during that time period???

[vickey_20]

What I did: I changed the home directory of a user with predefined alias( which really make my job easy)

What happened: In the new directory everything is gone. No alias are present ( which were earlier stored in .bashrc)

Now what I did:

alias cls=clear

This code executes perfectly but doesn't work. So if I could know there is it storing the alias temporarily I could fix this problem.

In the memory stack associated to the process that's the current shell session. Nowhere else, not in your disk anyway if that's what you meant.

This code executes perfectly but doesn't work.

That's what I call a paradox. I guess you mean that the alias sentence gives no error but when you run "cls" nothing happens. Are you sure that the alias was defined correctly? You can use "alias" without arguments to see the current aliases. Check it.

The alias command show the cls=clear and now executes perfectly fine. But when I change the the shell to csh and give

alias cls=clear

again it executes without any error. But this time in the csh shell on issuing the alias command I can't see the cls=clear which I earlier saw in bash shell

Aliases are a functionality from your shell. So, check the csh man page. I know nothing about csh at all. The syntax might be different than this of bash.
