need for a script file

sirrus_linux · 02-25-2005, 11:47 PM

Hello,

I am totally lost when it comes to writing automated scripts in linux !

I need to excute a set of commands everytime that my linux router box boots up. So can anyone help me by giving some examples of how to mount the floppy drive ( there is an entry in the /etc/fstab ) and run a set of commands from the floppy drive to excute a software which is in the floppy drive.

Thanks ..... in advance.

hello!
Well I know very little about writing scripts but I found some useful information here:
http://www.atnf.csiro.au/people/rgoo.../boot-scripts/
it basically talks about implementation run-levels and what to modify.
I hope it is of some use to you,
good luck

You'll have to create a script. Place it in /etc/rc.d or /etc/init.d and make it executable. The script code would look something like what is typed below. Since you didn't specify what is being run on the floppy, I just called them command1, command2, and anothercommand. Whatever executable you wish to run, make sure that the ./ is in front of it, or use the full path like the last command.

#!/bin/bash

# Mount the floppy
mount -t vfat /dev/fd0 /mnt/floppy

# Change to floppy and run commands
cd /mnt/floppy
./command1.script
./command2.script
/mnt/floppy/anothercommand.script

I read that the /etc/rc.d is like the "orchestator" and it is for such saying the main script, it runs all other scripts, is this correct or did I missunderstood??
also I have another question:
what does it mean to make it executable??
Thanks and im sorry if im being annoying but I am really new to this and very anxious to learn

I would agree with that statement. The scripts are what get executed when a runlevel is changed, meaning if you shutdown, reboot, boot up, or change to a different runlevel for maintainance or something.

u can make a script executable by
chmod 0755 /path/to/script

after that u can invoke the script as a program.

/path/to/script

from the shell
