how to install scripts? noobie question?
 
hello,

i'm trying to understand x-terminal and i want to cleanup my rootfs memory with help of the wiki on the site:

http://wiki.maemo.org/Free_up_rootfs_space

in this wiki they say:

This script will move some unnecessary files on rootfs to /home/opt/ to free up space on rootfs.

First, create a file, move-to-opt.sh for example, containing this script:


But with what program do i create this file? i tried it in notes and then saved it under .sh but it was still a note and offcourse it didnt work in x-terminal?

can someone please help me understeand scripts?

yap.
you could even just use the editor or wordpad but the syntax highlighting is very comfortable. :)
(especially if you want to understand what the script is doing and how it is doing)

copy&paste it. save it with .sh extension. copy it on your n900. open xterm. get root rights (install rootsh and type "sudo gainroot") make it executable with "chmod +x bla.sh" and then just run it with ". bla.sh" or "sh bla.sh".

BUT: please be aware... if you don't know what the script is doing exactly.. it could lead to some problems... if not right now - then maybe in the futuere (next update or so)

you have to "cd" into the directory where you stored the file first or write the full path in the command.

three examples when you copied the file in the documents directory via usb:

relative:
(when you open up xterm you're in /home/user/)
Code:
chmod +x MyDocs/.documents/move-opt.sh
absolute:
Code:
chmod +x /home/user/MyDocs/.documents/move-opt.sh
or first cd into the right directory:
Code:
cd MyDocs/.documents
chmod +x move-opt.sh
maybe you should learn how to get along with the terminal first before you do something big like moving system files around and symlinking them automatically....

unplug the usb first. ^^
and the command line is case sensitive.
