Code:
awk '($6 -= ($6>12)) && ($1 += ($1<11)?2:0)' OFS="\t" file

These can also be written as:
Code:
awk '{$6 -= ($6>12); $1 += 2*($1<11); print } ' OFS="\t" file
awk '($6 -= ($6>12)) && $1 += 2*($1<11)' OFS="\t" file

under the same conditions.

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
