renaming files in the directory
suppose i have a few file like "a b c.txt" , "hello world.c" etc...(files that have space between them in their filenames).

how do i change their filenames to "a_b_c.txt" and "hello_world.c" respectively?

heres what i have tried...but failed
Code:
[c_d@localhost dummy]$ find -name "*" -exec mv "{}" "`echo {} | tr " " "_"`" \; #the command that i m trying
mv: `.' and `./.' are the same file
mv: `./d e f' and `./d e f' are the same file
mv: `./dummy.sh' and `./dummy.sh' are the same file
mv: `./hell owr w' and `./hell owr w' are the same file
mv: `./j' and `./j' are the same file
mv: `./k' and `./k' are the same file
mv: `./file1' and `./file1' are the same file
mv: `./2' and `./2' are the same file
mv: `./a b c' and `./a b c' are the same file
[c_d@localhost dummy]$

this is how i broke it down

find command finds a file. it then executes mv. the mv processes the code `echo <filename> | tr " " "_" ` so output of "a b c" would be transilated to "a_b_c" and this output becomes the "DEST" in "mv SOURCE DEST" command ...where SOURCE is the <filename>

why shouldnt this work?

amarchiver

AMARCHIVER(8)						  System Administration Commands					     AMARCHIVER(8)

NAME

       amarchiver - Create, extract or list amanda archive

SYNOPSIS

       amarchiver --version|--create|--extract|--list [--verbose] [--file file] [filename]...

DESCRIPTION

       Amarchiver manipulates amanda archive file. On creation, amarchiver doesn't recurse into directories. If a filename specifies a directory,
       it will be ignored. If it specifies a character device, amarchiver reads the device and archives the data. If a filename specifies a named
       pipe, amarchiver reads the named pipe and archives the data.

       Note that this tool is more limited than the Amanda archive library, and may not be appropriate for some archive files -- particularly
       those which use non-strings in their filenames.

OPTIONS

       --version
	   print the amarchiver version

       --create
	   Create an amanda archive. Only the supplied filenames are included. With one --verbose, lists the filenames. With two, lists the
	   filenames and sizes.

       --list
	   List the filenames in an amanda archive. No additional filenames are allowed on the command line.

       --extract
	   Extract an amanda archive. If filenames are supplied, only those files are extracted. Files are created in the current directory,
	   suffixed with a dot ('.') and the attribute ID.

       --verbose
	   Give more information.

       --file file
	   Create, list or extract from the given file instead of stdin/stdout.
