How copy just line in text file with cat? (SOLVED)

kramerxiita · 2008-06-03 18:31:05

Hi.

How i make to copy just only line in text file with cat?

For example:

[:0.0]
file=/home/Arch/./.wallpaper.png
mode=0
bgcolor=# 0 0 0

I want copy just "/home/Arch/./.wallpaper.png" part.

Actually i want create a shortcut for last wallpaper set from Nitroget, then i put this in SLim background.

Recently i use hsetroot for wallpaper (~/.wallpaper.png) and i create a shortcut in /usr/share/slim/theme/MYTHEME whith ln -s ~/.wallpaper.png /usr/share/slim/theme/MYTHEME/background.png.

I want make a same with Nitrogen.

I now this looks like crazy, but...

Sorry my English.

kramerxiita · 2008-06-03 18:37:22

Yes, don't work for create shortcut for image.

kramerxiita · 2008-06-03 18:41:00

Just adding something. My idea is when a change wallpaper, SLim backgroung change too.

When a use hsetroot this happen.

Thanks

"sed -n 2p file.txt". Where 2 is the line number that you want from file.txt.

How can you make SliM change the background ? You link the theme background to another file ?

Yes. In theme directory i put background.png shortcut for my wallpaper. So, when a change wallpaper, slim background change too.

Example:

ln -s mywallpaper.png /usr/share/slim/themes/default/background.png

So, Slim background always is my wallpaper.

Don't really know too much about linux commands. Perhaps using cat -n which places line numbers in each line and pipe the result to grep eg. cat -n file.txt | grep 2 | to sed etc to get rid of the line number.

try this and don't work.

Thanks anyway.

So the wallpaper has to be a *.png ?

No, jpg is possible. But when you create a symbolic link, remember put the extension too. If change png to jpg, change a symbolic link extension.

But, remember if slim theme directory have background.png and background.jpg, Slim always choice .png. So, put only one this.

cat file | awk -F= '$1 ~ /^file$/ {print $2}'

here's a oneliner to make the link:

F=$( cat test | awk -F= '$1 ~ /^file$/ {print $2}' ) ln -s $( basename $F ) $F

First thanks a lot for reply.

But, i don't understand. When a put a patch for files...

It could give me an example?

Thanks

klixon · 2008-06-04 05:27:10

just replace "file" with the actual filename, or replace "cat file" with the program that gives the output.
I saved the few lines you give in a file called "file" to test if it works. Cat just prints it, the awk-statement does the actual work.
It splits the lines into field using "=" as field seperator (-F= ) and checks if the first field is "file" ($1 ~ /^file$/), if so it prints the second field...

kramerxiita · 2008-06-04 13:27:49

So, command will be like this?

F=$( cat ~/.config/nitrogen/bg-saved.cfg | awk -F= '$1 ~ /^file$/ {print $2}' ) ln -s $( basename $F ) shortcut.png

A try this and don't work.

klixon · 2008-06-04 14:09:01

Stupid me for reading wrong

ln -s $( awk -F= '$1 ~ /^file$/ {print $2}' ~/.config/nitrogen/bg-saved.cfg ) /usr/share/slim/theme/MYTHEME/background.png

kramerxiita · 2008-06-04 15:25:09

\o/

This work perfect.

Thanks very very much, klixon.

klixon · 2008-06-04 15:59:43

My pleasure. Glad it worked.

Can you mark the thread [solved]?

kramerxiita · 2008-06-04 16:50:26

Make this.

Just another question.

This command don't accept large names.

Example:

Work: myimage.png

Don't work: my image.png

There a fix for this?

kramerxiita · 2008-06-04 21:29:56

The problem is with ln -s command, does not recognize space like terminal. For example:

In terminal: My\ Image.png
With avk command: My image.png

But i don't know as fix this, and make avk insert space or \ and shortcut work with name and spaces.

klixon · 2008-06-04 22:19:34

I understand the problem, but i'm too tired to think of something just now
Lemme sleep on in and hopefully i'll be able to cook something up tomorrow

I think enclosing the command expansion in quotes would work.
You can spell it My\ Image.png or "My Image.png"

And how make this?

kramerxiita · 2008-06-05 16:15:49

Maybe klixon know how make.

Sorry for up this topic, but a still try this work.

klixon · 2008-06-05 19:53:28

target=$( awk -F= '$1 ~ /^file$/ {print $2}' ~/.config/nitrogen/bg-saved.cfg ); ln -s "${target}" /usr/share/slim/theme/MYTHEME/background.png

This seems to work...

kramerxiita · 2008-06-05 20:37:25

Perfect now.

Thank you very very much, klixon.

Sorry for boring you.
