I have a server where I upload sometimes the new version of my software. For each upload, I have to incremente the build var contained in a file.ver, like #BUILD 345. Well, I cannot do this everytime manually, but I prefer a smart and fast solution, that increment the number of the version for each upload.

What's the easiest way? There is in bash a nice command to do that? Or a callback method written in C/C++?

You can use the command sed to replace strings in a file.

For example, if you have a file myfile with the following content:

// Some comments
// Version: #VERSION
// ...

You can use the following command to replace the version number:

sed -i 's/#VERSION/123/g' myfile

The -i means inline, i.e. modify the file content.

Do not redirect the output of sed back to the same file, as in sed ... myfile > myfile as you will lose the file contents. See Redirect output from sed 's/c/d/' myFile to myFile

Result:

// Some comments
// Version: 123
// ...

If you use Ant, this could be useful:

Use ANT to update build number and inject into source code

If you want this to be easy you should use the IDE or makefile for this otherwise will probably forget it sometimes.

Depends on which system OS , ... your using, but most IDEs have this feature VisualStudio can do this or you create a small script in your makefile.
