AWK or SED to add string at specific position
Greetings.
I don't have experience programing scripts. I need to
insert a string in a specific position of another string on another file (last.cfg), for example:
File
last.cfg before using script:
login_interval=1800
lcs.machinename=client04
File
last.cfg after using script:
login_interval=1800
lcs.machinename=newclient04
I read about awk and sed comands, by I'm not sure what use and how.
Please, I'll thank so much if someone may help me or tell me if this problem has been solve on another post.

IGAWK(1) Utility Commands IGAWK(1)
NAME
igawk - gawk with include files
SYNOPSIS

@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
