http://www.unix.com – Need a script to print a set of characters in different combination. What's the key to accomplish this. e.g charset: "Abcdefghij1" without quotes. Code: block 1: "Abcd" block 2: "efg" block 3: "hij1" I need this script to change the order of the characters and print it to stdout e.g print out the blocks separately Code: "Abcd" "efg" "hij1" "Acbd" "feg" "h1ji" "Adbc" "fge" "j1hi" ... Or is there a better way to accomplish this with something else? (HowTos)
