in reply to Argv problem

In most shells & is interpreted as "put this process in the background". So the shell is likely eating that, and leaving your script without. Try single or double quoting (depends on shell).

BTW, & is probably a poor choice for an argument. Can you change it to something else?

    Its a password field so it can have any value , so user can enter & also.

      It's probably a bad idea to let the user enter a visible password. That said, suggest that the user quote the password or escape special characters, noting that in some shells, some characters are ridiculously difficult to quote correctly.

      Also search here and elsewhere. A quick search turned up Inputting a password w/o having it displayed on screen, which may help.
