Redirecting path1 to path2
Hi All,

Code:
path1="/opt/YAK/N78"
path2="/opt/YAK/N79"

I need to do such a way that when I will invoke "cd $path1" it should redirect me to $path2.

Humm.. tried to use link, alias and export ....but nothing is working...
Another one is it should work for any user login....

Can we cheat link error messages when we use "/"?...
Regards,
Niroj

If you are trying to go in a PATH you are not authorized to, then it is normal that you could not get in.

Otherwise, alias or ln should work.

You cannot achieve this effect without changing $path1.
For example.
Code:
path1="${path2}" ; export path1

This seems clumsy to me, but I think it does what you want:
Code:
function cd()
{
    path1="/opt/YAK/N78"
    path2="/opt/YAK/N79"

    command cd "$@"
    if [ "$PWD" = "$path1" ]; then
        command cd "$path2"
    fi
}

Or rename the /opt/YAK/N78 to /opt/YAK/N78.bak en create a symbolic link:
Code:
mv "$path1" "$path1.bak" 
ln -s "$path2" "$path1"
