 [SOLVED] Script to write in .conf/text file.
Sub_title: Thanks L18L |
|
Hi !
Could someone help me create a script please ?
I would like, to integrate the text in a conf file, from a script with different options.
I know this is not well explained ...
I have a config file in / etc / xdg / lxsession / autostart.conf
Content =
| Code: |
@lxpanel --profile LXDE
@pcmanfm --desktop --profile LXDE
@xscreensaver -no-splash |
Using a script, is it possible to add characters in the file, in a precise location?
For example, by running the script, once configured, I want the conf targeted file looks like this :
| Code: | @lxpanel --profile LXDE
@pcmanfm --desktop --profile LXDE
@xscreensaver -no-splash
@hello world |
Of course, if you have a base, I could then adapt.
It's because, I do not know programming, but I can understand the script. 
Thanks, if you have questions. Since mine is not really precise...  I don't know how to explain it.
Cheers !

Easiest cases first
if you want just append
@hello world
to your file /etc/xdg/lxsession/autostart.conf (no spaces)
then
| Code: | | echo '@hello world' >> /etc/xdg/lxsession/autostart.conf |
will do this 
or if hello world is the content of par example file1
then
| Code: | | cat file1 >> /etc/xdg/lxsession/autostart.conf |
will do it
Inside, not at end?
use stream editor sed
and/or

Thank you L18L,
I tried with the 'echo' command, it helps me a lot!
Now, if does not bother you, I need again a few tips please .
I have this.
| Code: | @lxpanel --profile LXDE
@pcmanfm --desktop --profile LXDE
@xscreensaver -no-splash |
I'd get it like this:
| Code: | @xfce4-panel
@pcmanfm --desktop --profile LXDE
@xscreensaver -no-splash |
I tried with :
| Code: | | sed -n --line-length=1 -i[/etc/xdg/lxsession/LXDE/autostart] -e=@xfce4-panel |
But doesn't work 
It's to replace lxpanel with xfce4-panel, I'm sure I'm wrong in the line, but I do not know where exactly the script does not work.
My syntax is bad, I probably put the commands in the wrong places ...

replace
@lxpanel --profile LXDE
by
@xfce4-panel
in file /etc/xdg/lxsession/LXDE/autostart
| Code: | | sed -i 's/@lxpanel --profile LXDE/@xfce4-panel/' /etc/xdg/lxsession/LXDE/autostart |
You might use variables?
| Code: |
BEFORE='@lxpanel --profile'
AFTER='@xfce4-panel'
sed -i "s/${BEFORE}/${AFTER}/" /etc/xdg/lxsession/LXDE/autostart |
Note the double quotes because there are variables inside
