find -delete folders

Meson · 04-16-2008, 08:06 AM

I'm running the following command within a script:

Code:

find $fold -maxdepth 0 -type d -exec rsync -r {}/ $base \; -exec rm -fr {} \; 2> /dev/null

But I'd rather have:

Code:

find $fold -maxdepth 0 -type d -exec rsync -r {}/ $base \; -delete 2> /dev/null

But find doesn't seem to want to delete folders...

The entire script is:

Code:

#!/bin/bash

root=$1
if [ -z $1 ]; then root=`pwd`; fi

compact_f()
{
	find $fold -maxdepth 0 -type d -exec rsync -r {}/ $base \; -exec rm -fr {} \; 2> /dev/null
}

for ((year=2004; year < `date +%Y`; year++)); do
	base=$root/$year
	fold=$base.[0-9][0-9]*
	compact_f
done

for ((j=1; j < `date +%m`; j++)); do
	year=`date +%Y`
	month=$j
	if [ $month -lt 10 ]; then month=0$month; fi
	
	base=$root/$year.$month
	fold=$base.[0-9][0-9]*
	compact_f
done

for ((k=1; k < `date +%d`; k++)); do
	year=`date +%Y`
	month=`date +%m`
	day=$k
	if [ $day -lt 10 ]; then day=0$day; fi
	
	base=$root/$year.$month.$day
	fold=$base\_[0-9][0-9].[0-9][0-9].[0-9][0-9]
	compact_f
done

It takes my archive folders which are created like YYYY.MM.DD_HH.MM.SS when they are first generated. After the day is up, it compacts all of the folders for a particular day into one (YYYY.MM.DD), after the month is up it compacts all of the folders for that month into one (YYYY.MM), and the same for the year (YYYY).

It works pretty well, I'm just trying to speed it up a little. Any suggestions?

Sorry, I erred in my response. Please ignore.

I think you meant

Code:

find $fold -maxdepth 1 -type d ...

because "-maxdepth 0" returns only "."

and even so, "find . -maxdepth 1 -type d -delete" does not delete non-empty directories. It is equivalent to a simple "rm".

I think I want the depth to be 0 because I'm only searching for directories within the working directory ($root).

Let's say I have:

Code:

/2008.04.01_10.30.00
/2008.04.01_11.30.00
/2008.04.01_12.30.00
/2008.04.01_12.30.00/2008.11.11_11.11.11

I don't want the subfolder 2008.11.11_11.11.11 to be seen as a special folder by this script. It's just any other file/folder.

If I understood you correctly, this was my interpretation. look:

Code:

[miguel@babylon5 ~]$ cd tmp
[miguel@babylon5 tmp]$ mkdir meson
[miguel@babylon5 tmp]$ cd meson
[miguel@babylon5 meson]$ mkdir 2008.04.01_10.30.00 2008.04.01_11.30.00 2008.04.01_12.30.00 2008.04.01_12.30.00/2008.11.11_11.11.11
[miguel@babylon5 meson]$ tree .
.
|-- 2008.04.01_10.30.00
|-- 2008.04.01_11.30.00
`-- 2008.04.01_12.30.00
    `-- 2008.11.11_11.11.11

4 directories, 0 files
[miguel@babylon5 meson]$ find . -maxdepth 0 -type d
.
[miguel@babylon5 meson]$ find . -maxdepth 1 -type d
.
./2008.04.01_10.30.00
./2008.04.01_11.30.00
./2008.04.01_12.30.00
[miguel@babylon5 meson]$

(the subfolder 2008.11.11_11.11.11 was not seen by rsync, just like you want)
With maxdepth=0, rsync is just called once, with "." as source dir. None of 2008.04* are arguments to rsync.

There is another problem too. maxdepth=1 returns "." as first entry.
With maxdepth=1, rsync will process all dirs twice: one with "." and again for each dir in "."

Is that what you want or I missed something ?

I guess my idea wasn't so dumb after all. There is a sample in the find info page that uses -maxdepth 0. This setting tests files listed as arguments. For example: find filea fileb filec filed -maxdepth 0 -empty will test just the 3 files in the arguments and return if one is empty.

The example in the info find manual has a find command argument of xargs to supply the arguments.
A perl script modifies the result of the first find command and this is fed to "xargs find {} maxdepth 0 ...".

and what was your idea jschiwal ? You edited your post and I never had a chance to read it.

jschiwal · 04-16-2008, 01:30 PM

I found that my explanation did the same thing with -maxdepth 1 so it wasn't a good demonstration.
I created 4 files, two that were empty. I had 3 files listed in the find command: find filea fileb filec -maxdepth 0 -empty

After repeating this experiment with -maxdepth 1, I decided to stick with the example in the info file.
