sed over writes my original file (using sed to remove leading spaces)

Hello and thx for reading this

I'm using sed to remove only the leading spaces in a file
Code:
bash-280R# cat foofile
some text
 some text
 some text
some text
some text
bash-280R#

bash-280R# sed 's/^ *//' foofile > foofile.use

bash-280R# cat foofile.use
some text
some text
some text
some text
some text
bash-280R#

That works great, however I really don't want to rename the file.
I was hoping this would work

Code:
bash-280R# sed 's/^ *//' foofile > foofile

It just overwrites foofile and makes it blank.

Is there a way to get around this and keep the original file name w/ the modification of removing leading spaces.

I will be running sed in a script

Thank you for your help

L.

LIBBASH(7)							  libbash Manual							LIBBASH(7)

NAME
libbash -- A bash shared libraries package. DESCRIPTION
libbash is a package that enables bash dynamic-like shared libraries. Actually its a tool for managing bash scripts whose functions you may want to load and use in scripts of your own. It contains a 'dynamic loader' for the shared libraries ( ldbash(1)), a configuration tool (ldbashconfig(8)), and some libraries. Using ldbash(1) you are able to load loadable bash libraries, such as getopts(1) and hashstash(1). A bash shared library that can be loaded using ldbash(1) must answer 4 requirments: 1. It must be installed in $LIBBASH_PREFIX/lib/bash (default is /usr/lib/bash). 2. It must contain a line that begins with '#EXPORT='. That line will contain (after the '=') a list of functions that the library exports. I.e. all the function that will be usable after loading that library will be listed in that line. 3. It must contain a line that begins with '#REQUIRE='. That line will contain (after the '=') a list of bash libraries that are required for our library. I.e. every bash library that is in use in our bash library must be listed there. 4. The library must be listed (For more information, see ldbashconfig(8)). Basic guidelines for writing library of your own: 1. Be aware, that your library will be actually sourced. So, basically, it should contain (i.e define) only functions. 2. Try to declare all variables intended for internal use as local. 3. Global variables and functions that are intended for internal use (i.e are not defined in '#EXPORT=') should begin with: __<library_name>_ For example, internal function myfoosort of hashstash library should be named as __hashstash_myfoosort This helps to avoid conflicts in global name space when using libraries that come from different vendors. 4. See html manual for full version of this guide. AUTHORS
