Top Forums Shell Programming and Scripting How to search pattern in file? Post 302909944 by DHeisenberg on Monday 21st of July 2014 01:28:38 PM

The below code will print all the lines containing the required pattern,
Code:
awk '/S[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]B/{print}' file.txt

Ex:
file.txt
abcS12345678B hidi
ghdgh S87654321B hi
Hi helloo

output:
abcS12345678B hidi
ghdgh S87654321B hi


If you want the pattern to be a word, use the below code,
Code:
awk '/\<S[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]B\>/{print}' file1.txt

Output will be :
ghdgh S87654321B hi

The characters "\<" "\>" are used to search for a word pattern.

SC_WARTS2TEXT(1)					    BSD General Commands Manual 					  SC_WARTS2TEXT(1)

NAME
sc_warts2text -- simple dump of information contained in a warts file. SYNOPSIS
sc_warts2text [-d ip2descr-file] [file ...] DESCRIPTION
The sc_warts2text utility provides a simple dump of information contained in a sequence of warts files. The output is the same as that which would have been provided by scamper if the text output option had been chosen instead of the warts output option when the data was collected. The options are as follows: -d ip2descr-file specifies the name of a file with IP-address, description mappings, one mapping per line. See the examples section for further information. While the output of sc_warts2text is structured and suitable for initial analyses of results, the format of the output is not suitable for automated parsing and analysis as the output of sc_warts2text will change overtime with no regard to backwards compatibility. Analyses of the contents of a warts file should be made using specialised programs which link against the scamper file API. EXAMPLES
The command: sc_warts2text file1.warts file2.warts will decode and print the contents of file1.warts, followed by the contents of file2.warts. The command: gzcat file1.warts.gz | sc_warts2text will print the contents of the uncompressed file supplied on stdin. Given a set of IP-address, description pairs in a file name mappings.txt: 192.0.2.1 "foo" 192.0.2.2 "bar" then the command gzcat file1.warts.gz | sc_warts2text -d mappings.txt will print the description associated with a given destination address before each result is presented.
