Linux equivalent to a windows batch file?

[Nameless]

Hello fellow linux users!

my question:

Is there an equivalent to a windows batch file (*.bat) in linux? I used to have alot of fun with those in windows and they make simple tasks simpler.

For those of you who dont know what a batchi file is it is a file that you can enter dos commands in it and when you run the file it executes the command.

Thanks

SCRIPTS

Linux uses scripts for just about everything.

http://www.linuxnewbie.org/nhf/intel/programming/index.html

First line starts with

#!/bin/bash
or
#!/bin/sh

Add your commands and make the script executable.

Here's a sample of a script that I wrote to compile the kernel. I have another to cleanup, backup libraries etc. prior to compiling the kernel. And yet another to modify the initrd (initial ramdisk).

#!/bin/bash

Thankyou!

I shall have much fun with this newly acquired knowledge....

Thanks Again!

watts, clean up your code, man ;) Btw can you use C or C++ like scripts so they perform system tasks like your example? I figure that you could, but just checking before I waste my time. Thanks.

[bdg1983]

Never have learned to program in C though I certainly would like to one day.

If you have any suggestions to improve on my script, then please post them.

All I wanted was a script to take care of all the kernel compiling steps and it seems to work fine for what I want. There's always room for improvement though.

yes, you could, but you have to use csh (C Shell), instead of bash (Bourne Again Shell)
