Hi Franklin52,
thanks for your reply.
what i'm trying to do is commenting or uncommenting specific lines. for instance these repositories:
Code:
# deb http://www.lamaresh.net/apt lenny main
# deb-src http://www.lamaresh.net/apt lenny main

could be defined by setting the variable REPO to "lamaresh". however, doing so with the current sed command, it will take both lines while i want to be able to control which line get uncommented.
so i'm looking for something that can search for a string and commit a change in the line containing the search string, but skip the line if another search string is present. i hope this is clear?
so for instance, uncomment/comment if "lamaresh" and "deb" are found, but do nothing if "lamaresh" and "src" are found, with a result like this:
Code:
deb http://www.lamaresh.net/apt lenny main
# deb-src http://www.lamaresh.net/apt lenny main

NAME
approx - proxy server for Debian archive files SYNOPSIS
approx [OPTION]... DESCRIPTION
approx responds to HTTP requests made by apt-get(8). It maintains a cache of Debian archive files that have been previously downloaded, so that it can respond with a local copy when possible. If a file not in the cache is requested, approx will download it from a remote Debian repository and deliver the contents to the client, simultaneously caching it for future use. Over time, the approx server cache will grow to contain multiple, unneeded versions of Debian packages. The approx-gc(8) program removes these from the cache. OPTIONS
-c file, --config file Specify an additional configuration file. May be used multiple times. USAGE
approx is invoked by inetd(8). EXAMPLES
Suppose that a client machine's /etc/apt/sources.list file contains the following lines: deb http://apt:9999/debian testing main deb http://apt:9999/security testing/updates main deb-src http://apt:9999/debian unstable main In this example, apt is the hostname of the approx server machine on the local network. Each distribution, such as "debian" or "security", is mapped to a remote repository in the approx server's configuration file. For example, the approx.conf file on the approx server might contain the lines debian http://ftp.debian.org/debian security http://security.debian.org The mapping scheme is very simple. If the approx.conf file contains the line repository http://remote-host/initial/path then any request to the approx server of the form http://approx-server/repository/rest/of/URL is rewritten to http://remote-host/initial/path/rest/of/URL when there is a "cache miss", and that file is cached as /var/cache/approx/repository/rest/of/URL (Note that the repository name on the left-hand side is not included in the rewritten URL unless it is explicitly mentioned in the right- hand side's initial path.) FILES
/etc/approx/approx.conf Configuration file for approx and related programs. /var/cache/approx Default cache directory for archive files. SEE ALSO
approx.conf(5), inetd(8), approx-import(8), approx-gc(8), apt-get(8), sources.list(5) AUTHOR
