Good afternoon gang!  I'm working on a project that currently uses
Berkley's netcat (nc), however, during some research I stumbled on
ncat.  I can see that it's much more comprehensive so I'd like to
make the switch to using it instead, but I can't seem to get it
working right.  The project is basically a bash version of a web
server.  I'll post the working code below.  Any help would greatly
be appreciated!


while (( 1 == 1 )); do                # causes an infinite loop for
processing requests
    #nc -Cl $sOPTS "$iPORT" < "$SI" > "$SO" 2>>/tmp/debug.txt &   #
    nc -Cl $sOPTS "$iPORT" < "$SI" > "$SO" &
# netcat-openbsd
    #ncat $sOPTS -vvv -C -l $iPORT < "$SI" > "$SO" &
# ncat

    trap exitGraceful SIGINT                                    #
traps ctrl-C to exit this script
    head -n 1 "$SO" | procRequest > "$SI"
    trap - SIGINT

You will probably be happier with this (no while loop):

ncat -l -k $iPORT --sh-exec "cat \"$SI\""

Compare to some examples here:
