Top Forums Shell Programming and Scripting regex to delete multiple blank lines in a file? Post 302140276 by radoulov on Thursday 11th of October 2007 04:31:01 PM

Sure:

everything <>0 in awk is true (you can use whatever you want: 1,2 ... 42 ...), true means use default action, which is print the current record.

You could use this, if you prefer:

Code:
awk -- -42 RS= ORS="\n\n" filename

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
