how to install squid-2.5.STABLE13 on linux

admin — Tue, 09 Mar 2010 03:12:20 +0000

To build and install the Squid Cache, type:

% ./configure –prefix=/usr/local/squid
% make all
% make install

To run a Cache, you will need to:

1. customize the squid.conf configuration file:
% vi /usr/local/squid/etc/squid.conf

2. start the cache:
% /usr/local/squid/sbin/squid

If you want to use the WWW interface to the Cache Manager, copy the cachemgr.cgi program into your httpd server’s cgi-bin directory.

VI command - D & x

admin — Mon, 10 Aug 2009 03:16:45 +0000

D

The D command deletes from the cursor position to the end of the line. (D is a shortcut for d$.)

x

Often you want to delete only one or two characters. Just as r is a special change command to replace a single character, x is a special delete command to delete a single character. x deletes only the character the cursor is on.
