I downloaded 6 missing libraries for ffmpeg and wanted to undeb all of them.

Tried these commands as find`s help said, both errored the same:
Code:
sh-4.1# find /mnt/sdb3/deb_bin/ffmpeg_i386 -name lib*.deb -exec undeb
find: missing argument to `-exec'

sh-4.1# find /mnt/sdb3/deb_bin/ffmpeg_i386 -name lib*.deb -exec undeb {}
find: missing argument to `-exec'

Is it finding libs to undeb?

Code:

sh-4.1# find /mnt/sdb3/deb_bin/ffmpeg_i386 -name lib*.deb



edit: Yeah.... -exec doesn't seem to work


| xargs [command] works

I know from amigo .
I read on the net also to '{}' single quote or doubble quote the curved brackets .

Strange---nothing worked yesterday re "-exec", today everything works..quoted or non-quoted.

The error in the OP is that it needs either a \; or a \+ at the end of the -exec argument (as well as the {}). That's how find knows where the end is. The difference between \; and \+ is that with \; it runs the command once per find, whereas with \+ it combines the results into one command.

Code:
find /mnt/sdb3/deb_bin/ffmpeg_i386 -name lib\*.deb -exec undeb {} \;

#equivalent to:

undeb /mnt/sdb3/deb_bin/ffmpeg_i386/libCooper.deb
undeb /mnt/sdb3/deb_bin/ffmpeg_i386/libMarla.deb
undeb /mnt/sdb3/deb_bin/ffmpeg_i386/libStuart.deb
undeb /mnt/sdb3/deb_bin/ffmpeg_i386/libVal.deb


Code:
find /mnt/sdb3/deb_bin/ffmpeg_i386 -name lib\*.deb -exec undeb {} \+

#equivalent to:

undeb /mnt/sdb3/deb_bin/ffmpeg_i386/libCooper.deb /mnt/sdb3/deb_bin/ffmpeg_i386/libMarla.deb /mnt/sdb3/deb_bin/ffmpeg_i386/libStuart.deb /mnt/sdb3/deb_bin/ffmpeg_i386/libVal.deb


Also, it's a good idea to escape or quote name arguments that have asterisks, so that the shell doesn't try to expand them before sending them to find. Otherwise if you have any files in the local directory that match the name pattern, your name option will be expanded into them before being sent to find, which is probably not what you want.

The code technosaurus posted will work as long as the filenames don't have spaces in them. If there are spaces, it is better to use the -exec argument of find. Using -exec with the \+ can also be more efficient than a for loop, depending on what you're doing.

Thanks everyone...

Pizzasgood; I seem to recall ( I think ) amigo telling me this awhile back.

Note: I thought once I tried multiple files with undeb and it didn`t work.

# I see you`re a fan of Dune Pizzasgood. The original or the remake?

Added it to my code snips.
The code snips file is getting pretty long, time for a snips/clips manager.

I don't think I've ever tried undeb on multiple files.

I'm a fan of the books. Haven't gotten around to watching the movie yet. It's on my list of movies to watch sometime.

The original with Kyle MacLaughlin is my favorite, but hard to find.

The remakes; Dune, and Children of Dune are very good also.
