Using awk to replace strings
Hi.. I have a file that has the following content :
Code:
abc 213 24 213
pqr 456#34 678
xyz 213 45%213

i need to write an awk script that will replace the second 213 in all the lines, if it is present. The IFS can not be specified and can be random.

The number of lines in the file and the columns in each line are not fixed.

Please suggest a solution. Thanks!

Using sed to replace two different strings?

Hey everyone! Simple question - I am trying to use sed to replace two different strings. As it stands I can implement this as: sed -i 's/TIMEOUT//g' sed -i 's/null//g' And it works.

NAME

       sip-dig - Resolve SIP URIs.  This is an example program for sresolv library in synchronous mode.

       Author:
	   Pekka Pessi <Pekka.Pessi@nokia.com>

       Date:
	   Original Created: Tue Jul 16 18:50:14 2002 ppessi

Synopsis
       sip-dig [OPTIONS] uri...

Description
       The sip-dig utility resolves SIP URIs as described in RFC 3263. It queries NAPTR, SRV and A/AAAA records and prints out the resulting
       transport addresses.

       The default transports are: UDP, TCP, SCTP, TLS and TLS-SCTP. The SIPS URIs are resolved using only TLS transports, TLS and TLS-SCTP. If
       not otherwise indicated by NAPTR or SRV records, the sip-dig uses UDP and TCP as transports for SIP and TLS for SIPS URIs.

       The results are printed intended, with a preference followed by weight, then protocol name, port number and IP address in numeric format.

Command Line Options
       The sip-dig utility accepts following command line options:

       -p protoname
	   Use named transport protocol. The protoname can be either well-known, e.g., 'udp', or it can specify NAPTR service and SRV identifier,
	   e.g., 'tls-udp/SIPS+D2U/_sips._udp.'.

       --udp
	   Use UDP transport protocol.

       --tcp
	   Use TCP transport protocol.

       --tls
	   Use TLS over TCP transport protocol.

       --sctp
	   Use SCTP transport protocol.

       --tls-sctp
	   Use TLS over SCTP transport protocol.

       --no-sctp
	   Ignore SCTP or TLS-SCTP records in the list of default transports. This option has no effect if transport protocols has been explicitly
	   listed.

       -4  Query IP4 addresses (A records)

       -6  Query IP6 addresses (AAAA records).

       -v  Be verbatim.

Return Codes
       0when successful (a 2XX-series response is received) 1when unsuccessful (a 3XX..6XX-series response is received) 2initialization failure

Examples
       Resolve sip:openlaboratory.net, prefer TLS over TCP, TCP over UDP:

	$ sip-dig --tls --tcp --udp sip:openlaboratory.net
	       1 0.333 tls 5061 212.213.221.127
	       2 0.333 tcp 5060 212.213.221.127
	       3 0.333 udp 5060 212.213.221.127

       Resolve sips:example.net with TLS over SCTP (TLS-SCTP) and TLS:

	$ sip-dig -p tls-sctp --tls sips:example.net
	       1 0.500 tls-udp 5061 172.21.55.26
	       2 0.500 tls 5061 172.21.55.26
