Shell Scripting HELP!
 

hello friends ,
presently i am using ubuntu6.06.i am pretty new to linux . My question is like this

suppose i write a shell script that starts playing a song using mp3blaster .now i want to write some more commands in the script that controls the this player like its sound

NOTE:I am doing this from the Console .

example

[------------------------------------------------------------------------------------------------]
#! /bin/bash
#example.sh

mp3blaster xyz.mp3 # xyz.mp3 is in the same directory in which i am executing example.sh

# here i need a body that controls this mp3blaster plyer
# like i need to control increasing and decreasing the sound level automatically while execution is being done.
#
#
#
exit
[--------------------------------------------------------------------------------------------------]


my question is not regarding the mp3blaster . it is for any console based application.

i would appreciate greatly if someone can reply to this logically . i do have some basic idea about navigating the shell and the shell scripting in general.

thanking all in advance .

Have your script start with a menu of options for the user. Something like:
1. play a recording
2. increase volume
3. decrease volume
4. quit

Then a case argument to call a function to carry out the task:
case 1) play a recording
case 2) increase volume
case 3) decrease volume
case 4) quit

Have the script return from the function to the menu and wait for the next input.

hello bigrigdriver,
it does give a lotof keybindings,thats correct .but i dont want to press 4 everytime to quit (in ur example). the shell has to do that for me.
let me make it more specific .
suppose i want to play the song for 20 secs and then it should quit automatically.
how to achieve that with a script.

i hope this makes my question a bit more clear.

thanking all in advance .

For playing mp3s, try using mplayer instead, it can do everything you've mentioned.
