Top Forums Shell Programming and Scripting sed or awk command to replace a string pattern with another string based on position of this string Post 302656067 by guruprasadpr on Thursday 14th of June 2012 07:56:33 AM

When I ran the same command for the file specified, it is coming properly.


Code:
$ awk -F, '/INSERT/{for(i=1;i<=NF;i++){if ($i ~ /lastModified/){x=i;print;getline;break;}}}{y="0000-0000 00:00:00";sub(/[-0-9: ]+/,y,$x);}1'  OFS=, file
INSERT INTO `Table44` (`id`, `action`, `date`, `description`, `modifiedId`, `object`, `performedById`, `schemaDifference_blob_reserved`, `schemaDifference_reserved`, `sourceIPAddress`, `zoneId`, `lastModified`) VALUES
(1,'Change','2011-05-05 00:00:00','User Account Updated',3,'Account',1,NULL,NULL,'',1,'0000-0000 00:00:00');


Make sure your file should be in the format as you had specified in the sample earlier like:
Code:
INSERT INTO . ............ VALUES
(.....................),
(.....................);

not all in the same line.

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
