Most UNIX operating systems have the capability for the administrator to generate a kernel-based core dump. Linux users must have a kernel that supports the Magic SysReq key. Solaris on SPARC is set to go; Solaris on Intel processors requires booting the Solaris kernel with the kmdb kernel mo...
More often than not, the best way to get relevant information is to query the system when you need the information, instead of continually producing data. In fact, every Unix system provides many tools for obtaining system information:ps,netstat,vmstat, and so on. ...
One of the key features of Visual Studio Code is its great in-built debugging support for Node.js Runtime. For debugging code in other languages, it provides debugger extensions. The debugger provides a plethora of features that allow us to launch configuration files, apply/remove/disable and ...
Unix signals are a basic form of interprocess communication. For example, one of the signals, SIGSTOP, can be used to save the state and pause execution of a process, while its counterpart, SIGCONT, is sent to a program to resume execution. Both of these signals can be used by a de...
Test long scriptsin a modular fashion. In other words, do not try to write the entire script before testing any portion of it. Write a piece and get it to work before adding the next portion of code. Usedescriptive variable and function namesand avoid using single-character names. ...
The following is part of the shell script that I have used—it was written for the standard shell on Unix (should work on Bash, Ksh, etc.), but similar scripts could be written in other shells or as a DOS batch file: # These guys must be present in my classpath... export CLASS...
A d at the beginning of a set of UNIX file permissions indicates that the file in question is a directory, not a normal file. The c flag indicates that the file should be compiled but not executed—it's for testing to make sure your script compiles properly. True. There are a number...
scripts and reloading the definitions in them without calling code protected by an if __name__ == "__main__" clause.-i run the file in IPython’s namespace instead of an empty one. This is useful if you are experimenting with code written in a text editor ...
Free dbg front-end (dbg-cli) for Linux/Unix can be used to debug scripts either directly or under DDD 3.3.9 (GNU debugger). Also see RedHat 7.3, YellowDog and Mandrake distributions atRPM Findsite. Seescreenshots here. Version comparison. ...
On Unix you need to pass -DCMAKE_BUILD_TYPE=Debug to cmake to compile with debug information. Building MariaDB 5.3 and Older Here is how you compile with debug on older versions: Use the scripts in the BUILD directory that will compile MariaDB with most common debug options and plugins,...
