1. this looks like you've got a single quote (') at the start, then a backquote (`) at the end.
They should both be single quotes.
alias myloc='cd /export/nfs1-34/`
I have my own .bashrc file which i will use and i cant load them
is unclear; please re-write differently
3. aliases aren't 'executed'; they are set into your env, so that when you type 'myloc', you get the associated cmd executed.
Can you clarify what you are trying to achieve?
