Top Forums Shell Programming and Scripting awk to subtract from values in file Post 302957652 by SkySmart on Tuesday 13th of October 2015 05:35:11 PM

Code:
awk -F, '{A=strftime("%a %b %d %T %Y,%s",$3);if(A ~ /Oct 12.*2015/){split($NF, B,"--");print $1 "-" $3 "_" B[2]-B[1]}}'  Input_file

The above command works beautifully. however, i'd like for it to pull out all records it finds in the log from the point the search pattern is found, to the end of file.

right now, it only shows the line containing the search pattern.

Code:
-sh-4.1$ 
-sh-4.1$ awk -F, '{A=strftime("%a %b %d %T %Y,%s",$3);if(A ~ /Oct 12 13:55.*2015/){split($NF, B,"--");print $1 "-" $3 "_" B[2]-B[1]} }' input_file.txt
0-1444683349_0
-sh-4.1$ 
-sh-4.1$

IGAWK(1)							 Utility Commands							  IGAWK(1)

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
