Programming

Hi,

I'm trying to build my own little shell as an exercise. I want to run emacs from my shell so I'm using execvp() command. The problem is when I run it with arguments at background (e.g "emacs file1 &") it stays "hung" (I don't get the prompt back) while without arguments it runs ok ("emacs &" runs at bg without problems. any idea why?

thanks

edit by bakunin: your question seems to be more programming-related than "shell-scripting". I transfer your question to the "Programming"-board.

Without seeing the code you're using to set up the arguments and environment before calling execvp() to overlay the calling process, it is hard to guess at what might be going wrong.

The pathnames of utilities vary from OS to OS and, in some cases, from installation to installation. It would help us help you if we know what OS you're using, how you have $PATH set, and the absolute pathname of emacs on your system. (If there is more than one version of emacs installed, provide the pathname of the emacs you want to use.)
