Moving files

I'm struggling with batch files moving.

I have several files named "file  001.jpg"   #contains two blank spaces
or "file 002.jpg"                            #contains one blank space

I would like to know how to move them using system() in awk.

I can print them:

ls | awk '{print $1"_"$2}'

but how to move them from source to target file?

Well, there are several approaches to same task. Awk is handy as its
syntax is really space saving.
Sorry, if I date too much, but can you tell me what  "set -- $a"
exactly does?

sets the postional parameters $1, etc. to be whatever space-separated
values are stored in $a. For more details, look up the "set" command in
your shells man page (e.g. http://www.rt.com/man/ksh.1.html for ksh).

Thank you for your reply. I looked up "set" command in BASH manual
page, but I still don't understand how it works.

What don't you understand?

There are three functions to set (taken from the bash man page):

1.  Without options, the name and value of each shell variable
are displayed in a format that can be reused as input.

2.  When options are specified, they set or unset shell
attributes. E.g., set -f, set -x, set +v

3.  Any arguments remaining after the options are processed are
treated as values for the positional parameters and are
assigned, in order, to $1, $2, ...  $n.

Set allows you to restate the shell's command line. You can set
shell options and replace positional parameters. If you write

set $whatever

the shell expands the shell variable `whatever', then divides it up
using the value of IFS or white space if IFS is not set, and assigns
each piece to a positional parameter. For instance

whatever="a b c"
set $whatever
echo $2

will print `b'. This doesn't work correctly if $whatever has no
value or it begins with - or +. I used -- to say that the rest
of the command line should be assigned to positional parameters.

whatever="-a b c"
set $whatever
echo $2 # prints c
set -- $whatever
echo $2 # prints b
