Basic Unix bash script help

Hello there

Been using Unix bash scripting for two days now so am very new to this. I am currently doing a project now and i'm basically making a noughts and crosses game (or tic tac toe).

I have created the board using an array. When I try and check to see if the array is empty using an If function it says integer expression expected.

the code is as follows


if eval [ \$board$col1[$row1] - eq 1 ]


the 1 represents the empty space.

Cheers for any help

NAME
make-gnome-freecell-board, make-aisleriot-freecell-board, make-microsoft-freecell-board, make-pysol-freecell-board - Programs to generate boards to be used as input to Freecell Solver. SYNOPSIS
program [-t] board-number or for make-pysol-freecell-board: program [-t] [-F] board-number [game-string] or for make-aisleriot-freecell-board: program [-t] board-number [game-string] DESCRIPTION
These programs are command-line programs that can generate the initial board of the Freecell games of several popular Solitaire implementations. Those boards can be in turn be inputted to fc-solve by means of a pipeline, or placed inside a file for safe-keeping. make-pysol-freecell-board and make-aisleriot-freecell-board also accept an optional third argument which indicates the game type. This type defaults to Freecell, but is useful for generating the boards of other games. Note that using this flag does not preclude one from using the "--game" flag of fc-solve. make_pysol_freecell_board.py accepts another parameter called -F or --pysolfc that deals the PySolFC boards instead of the classic PySol ones. A common paradigm for using those programs is something like: bash:~$ make-microsoft-freecell-board 11982 | fc-solve -l gi If the "-t" option is specified, then the 10 cards are printed with "T"'s, instead of "10"'s. While this does not have any effect on fc- solve it may prove useful for other solvers or solitaire implementations which do not accept "10"'s. Here is a short description of each program: make-gnome-freecell-board Generate the boards of the standalone Freecell program that comes with the GNOME desktop. make-aisleriot-freecell-board Generate the Freecell boards of GNOME's AisleRiot. make-pysol-freecell-board A Python script that generates the boards of the various games of PySol. make-microsoft-freecell-board A program that generates the boards of Microsoft Freecell and of the Freecell Pro implementation of Freecell. OPTIONS
board-number is the board number as a decimal number. game-string is a string describing the game. Valid strings and their respective games are: bakers_game - Baker's Game (*) bakers_dozen - Baker's Dozen (Broken) (*) beleaguered_castle - Beleaguered Castle (*) citadel - Citadel cruel - Cruel der_katz - Der Katzenschwantz die_schlange - Die Schlange eight_off - Eight Off (*) fan - Fan forecell - Forecell freecell - Freecell (the default) good_measure - Good Measure ko_bakers_game - Kings' Only Baker's Game relaxed_freecell - Relaxed Freecell relaxed_seahaven - Relaxed Seahaven Towers seahaven - Seahaven Towers (*) simple_simon - Simple Simon (*) streets_and_alleys - Streets and Alleys make-aisleriot-freecell-board supports only the games marked with an asterisk (*).
