Help :: Simple Shell Scripting
Hello,

I want to find the "IP-OF-SERVER" in /etc/squid/squid.conf And replace it with The IP of server.
I know this command returns the IP of server :
Code:
ifconfig  | grep 'inet addr:'| grep -v '127.0.0.1' | cut -d: -f2 | awk '{ print $1}'

And I can replace with sed. :
Code:
sed -i 's/IP-OF-SERVER/#REPLACEMENT/g' /etc/squid/squid.conf

How I can combine the above commands together so that it replaces IP-OF-SERVER phrase with the ip of server automatically ?
Sometimes the code :
Code:
ifconfig  | grep 'inet addr:'| grep -v '127.0.0.1' | cut -d: -f2 |  awk '{ print $1}'

returns more than 1 ip if the server has more than 1 ip.
I just want to replace IP-OF-SERVER phrase with the first ip in list.


Best Regards

ext_file_userip_acl

ext_file_userip_acl(8)					      System Manager's Manual					    ext_file_userip_acl(8)

NAME

       ext_file_userip_acl - Restrict users to certain IP addresses, using a text file backend.

       Version 1.0

SYNOPSIS

       ext_file_userip_acl [-dh] [-f file name ]

DESCRIPTION

       ext_file_userip_acl is an installed binary. An external helper for the Squid external acl scheme.

       It works by reading a pair composed by an IP address and an username on STDIN and matching it against a configuration file.

OPTIONS

       -d	   Write debug info to stderr.

       -f file	   Configuration file to load.

       -h	   Display the binary help and command line syntax info using stderr.

CONFIGURATION

       The squid.conf configuration for the external ACL should be:
	      external_acl_type type-name %SRC %LOGIN /path/to/ext_file_userip_acl -f /path/to/config.file

       If the helper program finds a matching username/ip in the configuration file, it returns OK , otherwise it returns ERR .

       The configuration file format is as follows:
	      ip_addr[/netmask]   username|@group|ALL|NONE

       Where ip_addr is a dotted quad format IP address, the netmask must be in dotted quad format too.

       When the second parameter is prefixed with an @ , the program will lookup the /etc/group file entry for the specified username.

       There are other two directives, ALL and NONE , which mean
