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:
Code:
-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 Smilie

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 Smilie :

Code:
#!/bin/bash

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

                              DIALOG_CANCEL=1
                              DIALOG_ESC=255
                              HEIGHT=0
                              WIDTH=0

                              display_result() {
                                dialog --title "$1" \
                                  --no-collapse \
                                  --msgbox "$result" 0 0
                              }

                              while true; do
