Mplayer fifo.

Hi all,

First of all, sorry for the pastebin link. The code tags aren't working for me.

#!/bin/bash # while-menu-dialog: a menu driven - Pastebin.com

This is a channel "changer" shell script i'm working on. It uses dialog to display the menus.
It was working fine until yesterday. When I try to change channels, it simply does not work.

Here's the fifo:

-rw-r--r-- 1 ignatius users 18 Jan 28 07:49 /tmp/mplayer-control

I'm wondering, what's wrong with the code?

Also, a second question. For the "Custom" option, i'd like to add an input prompt, to allow input to select a channel from /etc/mplayer/channels.conf. Anyone know how I would do this?

Thank you.

What does that mean exactly?

CODE TAGS work for everyone...... they are not complicated and work just fine for everyone, including noobs with 1 post

No, when I try to encase the code with the code tags, it looks like it doesn't like the carriage returns and/or linefeeds.

Cut and paste... looks just like your pastbin code, poor formatting and all :

#!/bin/bash

                              # while-menu-dialog: a menu driven system information program

                              display_result() {
                                dialog --title "$1" \
