hi to all members in this forums .. Nice to meet you...
i only have a questions about command utility of "dd":
for example i will type:
pico trial
this is my file.
and save it and type chmod a+x trial
can there be a way that instead of typing:
Code:
dd if=trial of=trial.copy conv=ucase
so that my output in script trial will all become UPPERCASE.
And i want to change this "dd" command to "copyconv" just like the functionality of "dd" command also.. and the "conv=ucase" i would like to do the "conv=u" so that the content of my script trial will become UPPERCASE..
Hi All,

Hi,
is it normal, that the IP alias (service IP) can't be seen with ifconfig -a , as eth0:1 for example
the IP is on the node, you can ping it, and open ports for that IP
look at this:
# ip addr

Hello,
I need to rediret the directory location at run time as:-

Being able to mark in an alias definition a point of minimal abbreviation, an old feature of VAX/VMS shell (DCL) would be really nice in modern *nix shells.
In DCL you used to be able to define an alias (in its own weird syntax) which would be something like this:
$ alias fuz*zyanimals="cat... (5 Replies)

dd
DD(1) General Commands Manual DD(1)NAME
dd - disk dumper
SYNOPSIS
dd [option = value] ...
EXAMPLES
dd if=/dev/fd0 of=/dev/fd1
# Copy disk 0 to disk 1
dd if=x of=y bs=1w skip=4
# Copy x to y, skipping 4 words
dd if=x of=y count=3
# Copy three 512-byte blocks
DESCRIPTION
This command is intended for copying partial files. The block size, skip count, and number of blocks to copy can be specified. The
options are:
if = file - Input file (default is stdin)
of = file - Output file (default is standard output)
ibs = n - Input block size (default 512 bytes)
obs = n - Output block size (default is 512 bytes)
bs = n - Block size; sets ibs and obs (default is 512 bytes)
skip = n - Skip n input blocks before reading
seek = n - Skip n output blocks before writing
count = n - Copy only n input blocks
conv = lcase - Convert upper case letters to lower case
conv = ucase - Convert lower case letters to upper case
conv = swab - Swap every pair of bytes
conv = noerror- Ignore errors and just keep going
conv = silent- Suppress statistics (Minix specific flag)
Where sizes are expected, they are in bytes. However, the letters w, b, or k may be appended to the number to indicate words (2 bytes),
blocks (512 bytes), or K (1024 bytes), respectively. When dd is finished, it reports the number of full and partial blocks read and writ-
ten.
