Top Forums Shell Programming and Scripting Using awk to change a specific column and in a specific row Post 303036299 by juggernautjoee on Friday 21st of June 2019 04:21:37 PM
Old 06-21-2019
To distinguish line 2, it will always start with - 02,193631306,000300032,1,
The issue with that command is that 0640 will change tomorrow to 0641 (or some other number). I know I can just go in and manually run that command every day, after looking at the file and changing the appropriate values. But i would like to just have something that either counts to the 33rd character in line 2, deletes the next 4 characters, and replaces them with 2400, or something to that affect.

Sorry for not being clear in the first few posts. All your help is much appreciated.

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).

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
