I try to automate almost all things in order to save time. Inexperienced sys admin and help desk staff working under me finds all these tools useful. It saves their time and avoids security issues. Automation allows help desk staff to do things that they don't have enough direct system knowledge to do themselves. However, selecting correct tool and applying correct methodology is very important.

It is useful to find out what another program was doing at the moment it crashed. I know most people will recommend GNU gdb, Nemiver, Valgrind or IDE such as Eclipse. I use gdb when it is really required; otherwise I debug the old fashioned way using printf() or cout statements. ]]> http://www.cyberciti.biz/tips/what-do-you-use-to-debug-linux-unix.html/feed 26 http://www.cyberciti.biz/tips/squirrel-portable-shell-and-scripting-language.html http://www.cyberciti.biz/tips/squirrel-portable-shell-and-scripting-language.html#comments Mon, 19 Jan 2009 06:42:27 +0000 nixCraft http://www.cyberciti.biz/tips/?p=4559 This may come handy while writing cross-platform scripts.

If you don't want to commit to the idiosyncrasies of a specific shell running on a particular platform, try the Squirrel Shell. The Squirrel Shell provides an advanced, object-oriented scripting language that works equally well on UNIX, Linux, Mac OS X, and Windows systems. Write a script once, and run it anywhere.

Squirrel is a high level imperative/OO programming language, designed to be a light-weight scripting language that fits in the size, memory bandwidth, and real-time requirements of applications like video games.

Python is a dynamic object-oriented programming language that can be used for many kinds of software development. It offers strong support for integration with other languages and tools, comes with extensive standard libraries, and can be learned in a few days. Many Python programmers report substantial productivity gains and feel the language encourages the development of higher quality, more maintainable code.]]> http://www.cyberciti.biz/tips/download-python-3.html/feed 1 http://www.cyberciti.biz/tips/linux-unix-word-wrap-command.html http://www.cyberciti.biz/tips/linux-unix-word-wrap-command.html#comments Tue, 25 Nov 2008 11:42:21 +0000 nixCraft http://www.cyberciti.biz/tips/?p=3649 fold is really nifty command line utility to make a text file word wrap.
