Since i am new in shell scripting, i need some help from you guys.
I am trying to implement an automata that reflects the attached photo..
The main idea behind is to take an array of (0 & 1)s from the user and terminate it by "end". Then, the string is send to the function to check wether it belongs to the automata or not. The bit string belongs to the automata only if the last bit ends up in a state that has a double circles. If it has one circle that means it does not belong.
I am stuck in how exactly i should automate the process in "case".
Any suggestions of how i can do the function..
Code:
#!/bin/bash
function autometa {
for (( i = 0 ; i<${#X[@]} ; i++ ))
do
case {X[$i]} in
0)
#HELP
;;
1)
#HELP
;;
*) echo "Invalid"
;;
esac
done
}
i=0
while :
do
echo "Please Enter A String of 0 & 1, Write (end) to terminate"
read x
if [ $x = "end" ]
then break
fi
X[$i]=$x
i=$((i+1))
done
autometa $X
echo ${X[@]}
I've got a strange problem with a single mail sender (it is one of
those large free mail providers). My mail server works well with
thousands of senders but not this one, so we have made a connection
dump and it seems that the three way handshake is not completed

fsaparse
fsaparse(3gv)fsaparse(3gv)NAME
fsaparse - parse a word-acceptor automaton file
SYNOPSIS
#include "wa.h"
fsafparse(fp, fsa)
FILE *fp;
Fsa *fsa;
DESCRIPTION
fsafparse parses a word-acceptor automaton file in the format described by DEAGL ("Data Exchange for Automata and Groups Language") (but
see the BUGS section below). fp should be a pointer to an open file containing the automaton. fsa should be a pointer to an Fsa struture
as defined in "fsa.h". Upon return, the automaton will have been written into this structure.
RETURN VALUES
On success, fsafparse() returns 1. On failure, it returns 0.
SEE ALSO getwordlist(3), getmatlist(3), fgetmatlist(3),
getmatlist(1), automata(1)BUGS
fsafparse is meant specifically for use with getwordlist(3) and getmatlist(3). It does not recognize the full language described by DEAGL.
It only recognizes that part of it which was present in the word-acceptor files that I was working with when I wrote it. I think this may
be sufficient for all word-acceptor automata, but I am not sure of this. Please let me know if you find word-acceptor files for which this
doesn't work.
