search all files and only empty directories using find command
 

Hi All,
I wanted to search all empty, non empty files and only empty directories.
Tried.
But did not work.
So how to search using single find command.
Please help.

have you tried this?

Thanks for the reply, but you did not understand my question.
The above command is listing only empty files and directories. But I wanted to search all files and also only empty directories using find command at one time. So please help.

Can you explain in more detail; your request doesn't make sense to me
'only empty dirs' conflicts with searching files. If a file is there, its obviously in a non-empty dir.
See also ' search all empty, non empty files' which is a contradiction as written....

Tnanks for the reply chrism01.
I am asking that is there a way to search in a single command by putting multiple types instead of searching as below by putting &&

Can any body please help for the above?

Please have some patience. The people who can help you can come at any time.

It also helps to explain very clearly what you want to do. Give some background information about your goal, so we can better understand it.


So you just want to combine multiple tests and actions? Well, find has \(..\) grouping brackets, so perhaps something like this?

BTW, recent versions of gnu find have a -newerxy option that can replace -newer, allowing you to specify a time stamp directly.

Here are a couple of good links about using find:
http://mywiki.wooledge.org/UsingFind
http://www.grymoire.com/Unix/Find.html

Sorry but I.m not sure I understand what you are after.

but here is a try.

you want a list of empty dirs or any file which are newer than T?


-o is Or
-a and

Note, -a is implied when you have two expr
e.g.
see man find for more details

I still don't understand why you want empty dirs and all files

if it is for this

and you want to exclude empty stuff from tar

You get the idea :)
I think I half understand the empty dir thing, nearly.

Thanks BASH Guru.
Excellent command.
I just wanted to backup using only tar whatever it found i.e even for those files/directories even if they have white space in their names. Please see the below.
But I am unable to take backup using tar
So is there a way either we can take backup of such files & directories without sending to output file or by sending to output file and then making list of paths into the array which can take backup. The same I have posted here and still I am stuck in this.
Once again thanks a lot and waiting for your kind reply.

David's find piped through sed

Not perfect as ? will match any char

This will be better , escape hell :D

Code:

---

tar -c $(find /data/cli/ \( -newer /tmp/timestamp -type d -empty -print \) -o \( -newer /tmp/timestamp -type f -print \)|sed s/\ /\\\\\ /g) -f YourTar.tar

---

Scratch that, not working

Yes.
Thanks a lot Firerat.
Now I wanted to take backup all of the above.
As you can see in above output, the colored file & directory respectively which are having white spaces in their names also should be backed up.
Excellent, For this only I was stuck since yesterday. Thanks a lot. But
It is backed up only files not directory(i.e "This is an empty directory")
And also I wanted it to be in tar.bz2 format only. So could you please provide a command for tar.bz2?
If you don't mind could please explain "sed s/\ /?/g". Since I am newbie in sed I did not understand that for what it is.

Thanks a lot BASH Guru & Firerat, worked great and now it is bakcing up diectories as well.:cool:
Could you please provide me the same command for tar.bz2 format.

Sure, my find was exluding empty stuff, as I thought thats what you needed, see above post which uses David's find which is what you want

the sed is quite simple
sed s/\ /?/g
sed is substituting ' ' with '?' , all of them ( group )
sed s/\ /?/
would result in just the first ' ' being substituted, the g at the end processes all the matches

man sed

sed ( stream editor ) is a big subject

? is a bit like *, but ? is treated as any single character,
which is why it is not perfect

I understood it now.
Thanks a lot. And waiting for your kind reply form BASH Guru & Firerat for tar.bz2 format.
