Dear Friends ,

Is it possible to generate a welcome message when I give the command "ls" from a particular user's home directory in Unix/Linux platform ?

suppose , in following example ,

bash-3.00# whoami
root
bash-3.00# ls

When I give ls command then it shows the output as well it gives a welcome message like "Welcome to the root's home directory" .

Is it possible to do ?

check any alias is set for ls.

Yes it is possible if alias is used
or
ls is re-written and this new ls is put in any directory appearing in PATH.
