SED to remove a line above and lines below.

SmilieHi All,

I need help on removing lines in a text file.

Sample file :
Quote:

Client=0x 0
IPAddress=113.211.45.33
Client=0
ClientV=0
........
Uncomp=0
Comp=0
When there is a match ip for IPAddress in my `cat ip.out`, proceed delete line above until string "Comp" is found.

Thank you very much.

I found very useful SED in this forum but i got no idea how to manipulate it.

Code:
sed -rn '/(0\.0000 *){6}/{n;n;x;d};x;1d;p;${x;p}'

Smilie

NAME
photon - generates photo albums SYNOPSIS
photon [OPTIONS] [PATH] DESCRIPTION
Photon generates clean, yet configurable, static HTML photo galleries. All of the work is done from the command line, and the resulting output can easily be configured by changing the template files found in /usr/share/photon/templates. To create a new template (skin), first create a new directory: mkdir -p ${HOME}/.photon/templates/my_theme/ Then copy the contents of /usr/share/photon/templates/photonv1/ to this new directory. Photon only needs three files to build pages: index.html used to display the content of a folder image.html used to display the page for an image movie.html used to display the page for a movie If a file is missing, then photon will throw an error and will not run. HOW TO BUILD A GALLERY
Quick start $ photon -o myoutputdir /photos Use the gimp plugin $ photon --resize-plugin=gimp -v -o myoutputdir /photos Change the size for all images and the thumbnail and keep the original photo $ photon --sizelist=0,1600x1200,800x600 --thumbsize=320x240 -o myoutputdir /photos Create a gallery from your custom template (skin) $ photon -k my_theme -o myoutputdir /photos See photon help $ photon --help OPTIONS
