apply a function twice successively with the same input in awk program
Hi !
It is a general question.
When an awk script looks like:
Code:
#! bin/awk
function example(i){
<body>
}
{
example(1) #the function uses input_1 and return output_a
}
{
example(2) #the function uses previous output_a as an input and returns output_b
}1
How can I tell the program to use the same input for both times I use the function and not using the output of the first invocation as input for the second invocation of the function??? Is it doable?
If someone could explain me it would be very nice.
Thanks!

Hi I am very new to Unix Shell. I have a question:
How do you check the input value against a reqex?
For example using korn Shell:
echo "Please enter revision month: \c"
read revmon
if $revmon | egrep -c = '{3}{2}"'
then
echo "OK"
else
echo "PLease re-enter a valid revision... (3 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.
