That ain't workin for me... That's always returning zero. Ok, I figured it out if you call your script "myrandom", then you need to do "./myrandom 25" (to generate a number between 1 and 25.
You could also just do "echo $((RANDOM % 25 + 1))" at the command line, and bypass the script altogether. Just replace the 25 with upper limit you need, and the 1 with the lower limit. Any scripters want to whip up a script that will ask for the upper limit , and then produce a random number and prompt if another should be done (or quit). Basically keep spitting out random numbers when the user asks for one, until they say they've had enough... :) Shawn Gustin Johnson wrote: > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA1 > > > For the next meeting, here is a script that will generate a random > number between 1 and a number that you specify as input. > > #!/bin/bash > > rnumber=$((RANDOM%$1+1)) > echo $rnumber > -----BEGIN PGP SIGNATURE----- > Version: GnuPG v1.4.3 (GNU/Linux) > Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org > > iD4DBQFGS5v5wRXgH3rKGfMRApM1AJYwOY6OsSfrASTAmCZ2yWJgxBXwAKCEiVak > hs8FKTBR/r6L4+uEJZBM5A== > =bony > -----END PGP SIGNATURE----- > > _______________________________________________ > clug-talk mailing list > [email protected] > http://clug.ca/mailman/listinfo/clug-talk_clug.ca > Mailing List Guidelines (http://clug.ca/ml_guidelines.php) > **Please remove these lines when replying _______________________________________________ clug-talk mailing list [email protected] http://clug.ca/mailman/listinfo/clug-talk_clug.ca Mailing List Guidelines (http://clug.ca/ml_guidelines.php) **Please remove these lines when replying
