Top Forums UNIX for Dummies Questions & Answers Replace all decimal values in a column Post 302937138 by RavinderSingh13 on Wednesday 4th of March 2015 12:14:08 AM

Hello Siya,

For your request not to change the formatting in file, I don't think so it is possible in a input file where space in between fields is inconsistent as in your provided input. As awk will consider it as same default width space only. If you need to change only field 6th then following may help.
Code:
 awk '{for(i=1;i<=NF;i++){if(i==6){$i="."}}} 1' Input_file

Thanks,
R. Singh

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
