You can try this with awk. Suppose you want to change the value of the section [supplies_res_6] of ammo_12x76_zhekan with 100, 1.0:

Code:
awk -F":| " -v var="6" -v v1="100, 1.0" -v opt="ammo_12x76_zhekan" '
$1 == "[supplies_res_"var"]" && !f {f=1}
f && $1 == opt{sub("=.*","= "v1);f=0}
1' file

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
