Top Forums Shell Programming and Scripting any savant ? using AWK/SED to remove newline character between two strings : conditional removal Post 302501179 by Chubler_XL on Wednesday 2nd of March 2011 09:40:53 PM

Two approaches:

Code:
awk '/^End [Tt]ransaction/&&g==3{print "";g++}g==3{printf $0; next}/^Begin Transaction/{g++} 1' infile

Code:
awk 'NR==3{f=split($0,A,"\n");print A[1];for(i=2;i<f;)printf A[i++];$0="\n"A[f]} $0=$0"\n"' RS= infile

Both the 2nd solution here and bartus11's post above rely on a blank line after the End line. Unlike Bartus11's solution the 2nd solution here ensures the Beg and End lines aren't joined up with the rest of the text, and restores the blank line after then End 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
