Shell Script Programming is of lots of fun. The following script prints a chess board with 8×8 squares interleaving black and white. Using simple loops 
and some simple math yields the chess board printing.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 | #!/bin/sh # https://helloacm.com for i in $(seq 1 8) do for j in $(seq 1 8) do S=$(((i+j)%2)) if [ $S -eq 0 ] then echo -n "\033[47m " # white else echo -n "\033[40m " # black fi done echo -n "\033[40m" # black, ensure it exists normally echo "" # new line done |
#!/bin/sh # https://helloacm.com for i in $(seq 1 8) do for j in $(seq 1 8) do S=$(((i+j)%2)) if [ $S -eq 0 ] then echo -n "\033[47m " # white else echo -n "\033[40m " # black fi done echo -n "\033[40m" # black, ensure it exists normally echo "" # new line done
This will print the following roughly. Please note that printing the black and white squares using echo command should take the special characters. The looping in BASH Shell can be reviewed at [here].
In [here], the script has been converted to Windows Batch.
