How to I pipe into a command with multiple arguments? I want to pipe the output of find /media/shared/music into chown <username> <output of find>

UNIX/Linux irritates me... I'm on Fedora right now lol

If i was to guess, i'd say you have to use quotes to group whatever needs to be grouped? I don't know.

Yes, there is a way.

chown -R user /media/shared/music

This will change the folder and all of its contents ownership to the user that you specify.

Here is the syntax
chown [ -f ] [ -h ] [ -R ] Owner [ :Group ] { File ... | Directory

-R means reclusive, aka continue to change until nothing left to change lol(within that directory) so if there are additional folders within the /music directory, it will change the ownership of those folders and their contents as well.

Nice - I didn't know there was a recursive flag.

Do you know how to do the pipe that way in general?

kc-tr · 06-03-07

I dont know that you can use it with the find command, however I have never tried. Also what exactly do you mean by pipe it out?

Take the output of 'find /media/shared/music' and have it as the second argument of chown

kc-tr · 06-03-07

so basicly.. Change ownership of all the files/subdirectories of that folder. Then find the contents? if so you could do..(if my syntax is right lol)

chown -R user /media/shared/music | find /media/shared/music -user user

the last "user" listed would be your username after the -R. Try that and see if it works.

Edit: a little more info on the command listed above. the | allows you to run two commands, run the first one then the second one. to make that line press shift \

That would pipe the output of chown into find

Forget chown and find for a second. What I want to do is take the output of any unix function and put it in as an argument for the second

ahh ok, well its not designed that way however you can do it manually, by making a text document for example with commonly used commands save the ones you want and create a shell script out of it, however even that would require it being edited every time you used it.

the os itself is not designed that way because there are many instances where that will cause a problem or a syntax error.

I'm positive that there is a way to do this in unix.

I could easily make a script to do it with any command/arg number but I would rather use the system as it is now
