Hi,
How can I generate a string of random characters (alpha+numeric) of a particular length ?
For e.g. for
n=5, output = 'kasjf'
n=10, output = 'hedbcd902k'
Also, please let me know if random (valid) dates could also be generated.
Thanks (7 Replies)

DESCRIPTION
ksh

-R
-r (raw mode) ignore the escape conventions of echo. The -R option will print all subsequent arguments and options other than
-n.
-p causes the arguments to be written onto the pipe of the process spawned with |& instead of standard output.
-s causes the arguments to be written onto the history file instead of standard output.
-u [ n ] flag can be used to specify a one digit file descriptor unit number n on which the output will be placed. The default is 1.
