1ª tentativa (não funcionou)
Você precisa incluir os diretórios, além dos arquivos:
rsync -zavC --delete --include '*/' --include='*.php' --include='*.js' \
--exclude="*" /media/datacod/Test/ /home/lucas/Desktop/rsync/
2ª tentativa
rsync -avzC --filter='-rs_*/.svn*' --include="*/" --include='*.js' \
--include='*.php' --exclude="*" --delete dir1/ dir2/
dados de teste
Eu escrevi esse script para criar alguns dados de amostra para testar isso. Aqui está esse 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
A execução produz os seguintes diretórios:
dir de origem
$ 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
dir de destino
$ tree -a dir2
dir2
|-- dir1
| '-- .svn
| '-- keepdir
|-- dir2
| '-- .svn
| '-- keepdir
|-- dir3
| '-- .svn
| '-- keepdir
'-- dir4
'-- .svn
'-- keepdir
Executando o comando rsync
acima:
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
Resultado final dir2:
$ tree -a dir2
dir2
|-- dir1
| |-- file1.js
| |-- file1.php
| '-- .svn
| '-- keepdir
|-- dir2
| |-- file1.js
| |-- file1.php
| '-- .svn
| '-- keepdir
|-- dir3
| |-- file1.js
| |-- file1.php

'-- .svn

Por que isso funciona?
A peça-chave deste script é usar o recurso de filtros de rsync
. Os filtros permitem remover arquivos do conjunto correspondente em vários pontos do comando. Então, no nosso caso, estamos filtrando todos os arquivos que correspondem ao padrão */.svn*
. Os modificadores -rs_
informam ao filtro que queremos filtrar tanto no lado da origem quanto no lado do destino.
trecho da seção FILTER NOTES da página man do rsync
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.
Veja man rsync para mais detalhes.
Dicas para descobrir isso (sugestão usando --dry-run
)
Ao descrever como fazer isso, pensei em mencionar a opção --dry-run
para rsync
. É extremamente útil ver o que acontecerá sem que o rsync
realmente ocorra.
Por exemplo
Usar o seguinte comando fará um teste e mostrará a lógica de decisão por trás de rsync
:
rsync --dry-run -avvzC --filter='-rs_*/.svn*' --include="*/" \
--include='*.js' --include='*.php' --exclude="*" --delete dir1/ dir2/

Na saída acima, você pode ver que os diretórios ./svn
estão sendo protegidos por nossa regra de filtragem. Insight valioso para depurar o rsync
