I'm using rsync to copy some files from a share to another.

Recursively, I need to:

  • Delete files at destination that were removed from the origin
  • Only sync php and js files
  • Exclude every other file type
  • Do not delete .svn/ directories at destination

If I use this:

rsync -zavC --delete --include='*.php' --include='*.js' --exclude="*" \
    /origiin /destination

Then rsync is not recursive because exclude="*" excludes all files but also folders

If I add --include="*/" then the .svn/ directory gets deleted (it also gets included)

How can I solve this mind blasting dilemma?

1st attempt (didn't work)

You need to include the directories in addition to the files:

rsync -zavC --delete --include '*/' --include='*.php' --include='*.js' \
     --exclude="*" /media/datacod/Test/ /home/lucas/Desktop/rsync/

2nd attempt

rsync -avzC --filter='-rs_*/.svn*' --include="*/" --include='*.js' \
     --include='*.php' --exclude="*" --delete dir1/ dir2/

test data

I wrote this script to create some sample data to test this out on. Here's that script, setup_svn_sample.bash:

#!/bin/bash

# setup .svn dirs
mkdir -p dir{1,2}/dir{1,2,3,4}/.svn

# fake data under .svn
mkdir -p dir1/dir{1,2,3,4}/.svn/origdir
mkdir -p dir2/dir{1,2,3,4}/.svn/keepdir

# files to not sync
touch dir1/dir{1,2,3,4}/file{1,2}

# files to sync
touch dir1/dir{1,2,3,4}/file1.js
touch dir1/dir{1,2,3,4}/file1.php

Running it produces the following directories:

source dir

$ tree -a dir1
dir1
|-- dir1
|   |-- file1
|   |-- file1.js
|   |-- file1.php
|   |-- file2
|   `-- .svn
|       `-- origdir
|-- dir2
|   |-- file1
|   |-- file1.js
|   |-- file1.php
|   |-- file2
|   `-- .svn
|       `-- origdir
|-- dir3
|   |-- file1
|   |-- file1.js
|   |-- file1.php
|   |-- file2
|   `-- .svn
|       `-- origdir
`-- dir4
    |-- file1
    |-- file1.js
    |-- file1.php
    |-- file2
    `-- .svn
        `-- origdir

destination dir

$ tree -a dir2
dir2
|-- dir1
|   `-- .svn
|       `-- keepdir
|-- dir2
|   `-- .svn
|       `-- keepdir
|-- dir3
|   `-- .svn
|       `-- keepdir
`-- dir4
    `-- .svn
        `-- keepdir

Running the above rsync command:

rsync -avzC --filter='-rs_*/.svn*' --include="*/" --include='*.js' \
     --include='*.php' --exclude="*" --delete dir1/ dir2/
sending incremental file list
dir1/file1.js
dir1/file1.php
dir2/file1.js
dir2/file1.php
dir3/file1.js
dir3/file1.php
dir4/file1.js
dir4/file1.php

sent 480 bytes  received 168 bytes  1296.00 bytes/sec
total size is 0  speedup is 0.00

Resulting dir2 afterards:

$ tree -a dir2
dir2
|-- dir1
|   |-- file1.js
|   |-- file1.php
|   `-- .svn
|       `-- keepdir
|-- dir2
|   |-- file1.js
|   |-- file1.php
|   `-- .svn
|       `-- keepdir
|-- dir3
|   |-- file1.js
|   |-- file1.php
|   `-- .svn
|       `-- keepdir
`-- dir4
    |-- file1.js
    |-- file1.php
    `-- .svn
        `-- keepdir

Why does it work?

The key piece to this script is to make use of the filters capability of rsync. Filters allow you to remove files from the matched set at various points in the command. So in our case we're filtering any files that match the pattern */.svn*. The modifiers -rs_ tell the filter that we want to filter on both the source side as well as the target side.

excerpt from the FILTER NOTES section of rsync's man page

  • An s is used to indicate that the rule applies to the sending side. When a rule affects the sending side, it prevents files from being transferred. The default is for a rule to affect both sides unless --delete-excluded was specified, in which case default rules become sender-side only. See also the hide (H) and show (S) rules, which are an alternate way to specify sending-side includes/excludes.

  • An r is used to indicate that the rule applies to the receiving side. When a rule affects the receiving side, it prevents files from being deleted. See the s modifier for more info. See also the protect (P) and risk (R) rules, which are an alternate way to specify receiver-side includes/excludes.

See man rsync for more details.

Tips for figuring this out (hint using --dry-run)

While describing how to do this I thought I'd mention the --dry-run switch to rsync. It' extremely useful in seeing what will happen without having the rsync actually take place.

For Example

Using the following command will do a test run and show us the decision logic behind rsync:

rsync --dry-run -avvzC --filter='-rs_*/.svn*' --include="*/" \
     --include='*.js' --include='*.php' --exclude="*" --delete dir1/ dir2/

total size is 0  speedup is 0.00 (DRY RUN)

In the above output you can see that the ./svn directories are being protected by our filter rule. Valuable insight for debugging the rsync.

Already tried this, as I said above. If I do this, then the .SVN directory gets also included (most likely deleted, because It doesnt exist in the origin, or modified). It is critical to leave the .SVN directory untouched. Thanks for the try anyway! :) –  canolucas May 17 '13 at 20:04
    
-C is supposed to ignore ".SVN/", but include="*/" includes it –  canolucas May 17 '13 at 20:07
    
No problem, thanks for the try –  canolucas May 17 '13 at 20:19
    
You are right. It should be .svn, editing the answer. Anyway, after renaming the issue remains. -C and include="*/" don't seem to be very close friends :( –  canolucas May 17 '13 at 20:27

Ok, after several tries I sorted this up:

rsync -vaiz --delete --exclude=.svn/ --include='*.php' --include='*.js' \
    --include='*/' --exclude='*' --prune-empty-dirs \
    --filter "protect .svn/" /origin /destination

Thank you

Great answer. My filter protects .svn/ dirs from --prune-empty-dirs in the case they are empty. Another approach, this one duplicating empty dirs: rsync -vaiz --delete --exclude=.svn/ --include='*.php' --include='*.js' --include='*/' --exclude='*' /origin /destination –  canolucas May 18 '13 at 0:22
    
The key of my approach is to --exclude=.svn/ before the --include's –  canolucas May 18 '13 at 0:23
    
Good answer as well. I would've suggested a exclude='.svn/' but I thought you wanted to use the -C. Glad you figured it out! –  slm May 18 '13 at 1:32
