The command " svn info " prints information about the current directory:
$ svn info Path: . URL: http://svn.example.c...where: Revision: is the last syncup (update) revision of the current TARGET (artifact/file/directory, whatever you call). This number bumps up to that of the current project revision number after you do an update. Last Changed Rev: is the revision number of the latest change for the current TARGET . If TARGET is a directory, it is the revision number of the latest change within the directory, including all subdirectories. However , this number is not accurate after you do a check in without a following update . The revision number for the file or directory you checked in will have higher revision number than its parent/ancestor....

This is an odd-ball content provider in that it doesn't provide database records, but provides a resource as a stream. It can be used to provide media files or XML resources. Start the project with:

When I used AssetManager to open an XML file in a ContentProvider :
getContext().getAssets().openFd("demo.xml");it failed with this exception:
java.io.FileNotFoundException: This file can not b...It turned out that openFd only works for asset files that are not compressed. It works on media files such as .mp3 , .jpg , .wmv etc., which are not compressed during packaging. XML files are compressed by dedault, causing openFd to fail. An Android ticket was opened on this issue. Till that is fixed, the workaround is to add an exclusion in build.xml :
<?xml version="1.0" encoding="UTF-8"?> <pro...

CVS has two commands, cvs tag and cvs rtag for creating and manipulating labels. cvs tag uses the local file system to determine which revisions to associate with the label, while cvs rtag works directly on the repository. You can tag before checkout with the rtag command. If you checked out, had a successful build and want to create a baseline based on the checked out versions, you should use the tag command.
# to add tag "my_tag" to module "my_module" on...

This is a script to tail a log file through the web browser. It uses AJAX, apache web server, mod_python, UNIX utilities tail (requires the --lines switch) and wc . The log file may reside on the web server or any other host accessible from the web server through SSH. Although it's written in python, it should be easy to port to other languages such as Perl. Apache httpd.conf :
LoadModule python_module modules/mod_python.so ...Python script:
