Xargs is pretty neat.  You have to remember that there are different
implementations of it, too, so xargs on Linux would probably be
different than xargs on *BSD (it always is different in my experience).
The differences would mainly be in switches and default behavior.

I use xargs with lots of different utilities, just depending on what I
need to do with whatever files I'm catching.  For example, let's say I
wanted to rename some files:

locate *.PDF | xargs -I % mv % `basename % .PDF`.pdf

It's handy if you have a bunch of files in one directory that you want
to check somehow:

ls *.{jpg,gif} | xargs -J % file % | grep -v 'JPEG\|GIF'

Moving files to another directory is a popular use:

locate *.suf | xargs -J % mv % /path/to/dir


Note that you do not always need to use xargs.

locate *.PDF | while read name; do
mv $name ${name%.PDF}.pdf
done


There's lots more you can do with it.  Your imagination is almost your
only limitation.  :-)

I'm no shell guru but how about something like

find ./yourdirectory -name "*pdf" -exec mv {} ./newdirectory \;

you may have to play with the syntax a little but wouldn't this do it?

Could you please give another realworld example of using xargs and
your definition of it. I had a glance through man xargs, but I enjoy input
from humans that use it as well. :)

Can't believe no one has used xargs yet...

find /path/to/messydir -name '*.pdf' -type f | xargs -I % mv \
/path/to/messydir/% /path/to/newdir/%

Try any unix primer or

man find
or
find /my/unorganized/dir -name '*.pdf' -type f -exec echo mv {} /my/pdfs \;

and pray that you do not have files with identical names.

Ar!  I aplogize to reply to my own message a second time!, but
something didn't sit well with me after my last reply so I double
checked my syntax and found that my original command would work with two
modifications -quote *.pdf and remove second {}:

find /path/to/dir -name "*.pdf" -exec mv {} /new/dir \;

..that should do it, but the other suggestions are just as
easy...whichever.

Sorry for the wasted bandwidth!  I'm done now! :)

Sorry, I wasn't thinking hereafter I double check the man page I saw
that -exec replaces {} with the path, not just the file namethe
above will not work...use the if;do;done syntax that someone else has
already posted.

Thanks!

This should do it.  Note the use of back-ticks to execute a command

for f in `find . -name "*pdf"`
do
 mv $f /target-directory
done

you don't say if you need to preserve any of the path information 
when you move the file. The other poster's suggestion might work: 
my take on it would be to use a for loop:

for i in `find /some/dir -name "*.pdf"`;
	do mv $i /some/other/dir;
done

First, turn on line-wrapping in your MUA.

find /path/to/my/libarary -name *.pdf -exec mv {} /new/dir/{} \;

okay, I am no expert, but here is a shot:

%find /path/to/search -name '*.pdf' -exec mv /destination/directory

I am a bit uncertain if the last part is correct, but this is close to
what you want, I think.
