I have a list of logs from bash command line and I need to validate their syntax.
From my investigation I know that bash -n option or tools like https://www.shellcheck.net/ are not sufficient because they do not recognize if executable for command exist or not.
Commands like command, hash or type, which could validate if command exist, but what I missed is how to check if their arguments are valid. (eg. I need to know that ls -l is valid and ls -nonexistingargs is not valid).
Any ideas how to do this? (solution for only build in bash commands is enough).

See the -n argument to bash:
Read commands but do not execute them. This may be used to check a
shell script for syntax errors. This is ignored by interactive
shells.

I need to print the source code of a VS2010 project (all files, around 400). Is there any way to automate this task?
Any option is good: whether it is directly to a "physical" printer or to a virtual printer (PDF printer).
It's not built into VS. But you can find a macro that does the job at http://msdn.microsoft.com/en-us/library/ms973240.aspx.
Also, a modified version is loacted at https://stackoverflow.com/a/683835/337294
A Project file is an XML file. You can extract the filenames and then pipe them to any tool you like. If you have any unix-like tools on your Windows system you can do the following to print all .cpp files:
grep -o "\".*\.cpp\"" MyProject.vcxproj | xargs cat

Is there any online batch file/ bash scripts validator? Let you drop the code in the textarea and check syntax errors? Or upload a file for validation.
I doubt it, since you can just do bash -n yourscript.sh
Searching, I couldn't find one either. Plenty of hits on using -n though...

Is there a Java library/API available to interact with Windows OS, like executing commands on the command prompt and returning the output back to the program?
You can use java.lang.Runtime.exec() to do it, but read this first.
Use the ProcessBuilder, which is available starting from Java 1.5!
It has the nice ability to let you redirect the error stream which makes you only have to cope with one InputStream to read from.
Good article here: Runtime.exec() and the API is here: link text
