Hey guys i'm creating a dos style rename script, so if a user types say q14.* as the 1st param and b14.* as the 2nd and will rename all q14 files to b14 but keep the extensions, so i've developed nearly the full script "i think", if i use echo(echo "if $1 had been renamed it would now be...

This is my first script and I wont get it working.. sorry for being a total noob but here it is:

Also tried su.sh "sausage" "sausage.txt" but... (2 Replies)
Hi,
I was asked to connect a KVM screen to a Sun Fire V440 last night so I connected it up but no joy and nothing on the KVM screen. I was told that a reboot may fix the problem so connected to the ALOM and rebooted. On the plus side, the KVM screen now works but I lost the ALOM connection.

urandom
RANDOM(4) BSD Kernel Interfaces Manual RANDOM(4)NAME
random , urandom -- random data source devices.
SYNOPSIS
pseudo-device random
DESCRIPTION
The random device produces uniformly distributed random byte values of potentially high quality.
To obtain random bytes, open /dev/random for reading and read from it.
To add entropy to the random generation system, open /dev/random for writing and write data that you believe to be somehow random.
/dev/urandom is a compatibility nod to Linux. On Linux, /dev/urandom will produce lower quality output if the entropy pool drains, while
/dev/random will prefer to block and wait for additional entropy to be collected. With Yarrow, this choice and distinction is not necessary,
and the two devices behave identically. You may use either.
OPERATION
The random device implements the Yarrow pseudo random number generator algorithm and maintains its entropy pool. Addditional entropy is fed
to the generator regularly by the SecurityServer daemon from random jitter measurements of the kernel. SecurityServer is also responsible
for periodically saving some entropy to disk and reloading it during startup to provide entropy in early system operation.
You may feed additional entropy to the generator by writing it to the random device, though this is not required in a normal operating envi-
ronment.
LIMITATIONS AND WARNINGS
Yarrow is a fairly resilient algorithm, and is believed to be resistant to non-root. The quality of its output is however dependent on regu-
lar addition of appropriate entropy. If the SecurityServer system daemon fails for any reason, output quality will suffer over time without
any explicit indication from the random device itself.
Paranoid programmers can counter-act this risk somewhat by collecting entropy of their choice (e.g. from keystroke or mouse timings) and
seeding it into random directly before obtaining important random numbers.
