Hi.
Code:
shuf -i 10-30 -n 1

produces, in 3 separate runs:
Code:
26
% shuf -i 10-30 -n 1
15
% shuf -i 10-30 -n 1
25

The shuf utility is part of GNU coreutils, Coreutils - GNU core utilities which you could download, configure, compile, etc., if your system does not have coreutils installed or available via your package manager -- easier for Linux than for one of the Unix systems, Solaris, *BSD, etc.

Many features, see on-line man page is at: shuf(1): make random permutations - Linux man page

Best wishes ... cheers, drl
