# ResourceSync tutorial exercises using resync

|
## Writing a Resource Dump
|
|
|
|
Relative to the base directory of the github distribution there is a directory
|
|
`tests/testdata/dir1` with two files, `file_a` and `file_b`. We can create
|
|
a Resource Dump of this directory, as if it were mapped to `http://example.com/dir1`,
|
|
with the following:
|
|
|
|
```
|
|
resync> ./resync-build -v --write-resourcedump --outfile /tmp/rd http://example.com/dir1 tests/testdata/dir1
|
|
Scanning disk from tests/testdata/dir1
|
|
Writing resource dump to True...
|
|
Total size of files to include in dump 65 bytes
|
|
Writing sitemap /tmp/rd00000.xml...
|
|
Wrote sitemap /tmp/rd00000.xml
|
|
Wrote ZIP file dump /tmp/rd00000.zip with size 623 bytes
|
|
Wrote 1 dump files
|
|
resync> zipinfo /tmp/rd00000.zip
|
|
Archive: /tmp/rd00000.zip
|
|
Zip file size: 623 bytes, number of entries: 3
|
|
?rw------- 2.0 unx 453 b- defN 20-Dec-16 10:58 manifest.xml
|
|
-rw-r--r-- 2.0 unx 20 b- defN 12-Jul-25 13:13 file_a
|
|
-rw-r--r-- 2.0 unx 45 b- defN 01-Sep-08 21:46 file_b
|
|
3 files, 518 bytes uncompressed, 325 bytes compressed: 37.3%
|
|
```
|
|
|
|
This can then be unpacked and the files checked:
|
|
|
|
```
|
|
resync> mkdir /tmp/rd
|
|
mkdir: /tmp/rd: File exists
|
|
resync> cd /tmp/rd
|
|
rd> unzip ../rd00000.zip
|
|
Archive: ../rd00000.zip
|
|
inflating: manifest.xml
|
|
inflating: file_a
|
|
inflating: file_b
|
|
rd> more manifest.xml
|
|

|
|
rd> more file_a
|
|
I am file a in dir1
|
|
rd> more file_b
|
|
I am file b in dir1, I am bigger than file_a
|
|
```
