Try this to get the concept...
Output
It will shift the arguments from right to left
Lets say, you have 3 arguments i.e. $1=a, $2=b, $3=c
Now you "shift" and try priting $1, it will print "b" and $2 will be "c" and there will no $3
There is an error when i am trying to use the shift command in this way:
($1 = -d, $2 = 123, $3 = -c etc etc)
for $arg in $@
do
case $arg in
"-d") shift; (so that the $2 will become the $arg now)
(and while it loop the 2nd time,)

hi all, when I press SHIFT at once it work like as
I've hold it (like CapsLock is On, but it Off) ! ... and if I press F1 (or another
function key) it put out 24z :(
it is occure on my remote sun 8 , xterm session
help me please ! (2 Replies)
Hi Folks,
In shell scripting the maximum no. of command line parameters becomes 9(Am i right). If we want to get more than 9 parameters we use the shift command.
Even here there are two possibilities.
1. Without the use of variables - The arguments are lost and the lost no. is equal to the... (6 Replies)
I am running a program where in I have this command
which is giving error the shift: number is not correct.
can you please tell me how shift actually works?
the line which is giving error is-

Is it related somewhere to... (2 Replies)
Hi,
I wrote one script, in between script needs to use 10th and 11th positional parameters, that time i used "shift". Here i am facing the below find problem,

I tried
1) I have read man pages for shift
2) Before but * and **
3) Simple shift with out giving... (4 Replies)

Hi,
Firstly, I did a search for this question both on this site and on the internet and have not been able to find a suitable answer that is not general in nature.
I have always been a Windows user. I use my girl friend's mac every now and then, but I always come back to windows. For a... (1 Reply)
think using shift would help me finish my script but cant get it work without your help. would appreciate if you give me a example with shift & counter in the same script so I can later work on that to my one.
Thanks and Good Luck! (1 Reply)
Hello,
I am reading one of the AIX manuals about shell scripting and (AIX 5) and I found this example when introducing to functions:
function usage
{
prog="$1"; shift
print -u2 "$prog: usage: $prog $@"
exit 1
}
This example is meant to be easy but I don't understand what it is... (5 Replies)
#!/bin/bash
hostname=$1; shift
for hostname in $1
do
ping $hostname
done
I want to run the above script as hostname.sh yahoo.com google.com cnn.com. I want to shift each hostname to $1. How can do that with above code as currently it's not shifting. (5 Replies)

DESCRIPTION
Each of these functions performs an in-place multiplication of two vectors and shifts the result.
For real data, the following equation is used:
xz[i] = xz[i] * y[i] * 2**(-shift)
where i = 0, 1, ..., (n - 1).
For complex data, the following equation is used:
tmp = xz[2*i]
xz[2*i] = (tmp*y[2*i] - xz[2*i + 1]*y[2*i + 1]) * 2**(-shift)
xz[2*i + 1] = (tmp*y[2*i + 1] + xz[2*i + 1]*y[2*i]) * 2**(-shift)
where i = 0, 1, ..., (n - 1).
PARAMETERS
Each of the functions takes the following arguments:
xz Pointer to the first element of the first source and result vector.
y Pointer to the first element of the second source vector.
n Number of elements in each vector.
shift Right shifting factor. The ranges of valid shift are:
1 <= shift <= 8 for U8, S8, U8C, S8C types
1 <= shift <= 16 for S16, S16C types
1 <= shift <= 31 for S32, S32C types
RETURN VALUES
Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
