UNIX and Advance Shell Scripting
Best UNIX/LINUX SHELL Training with 50+ Assignments
Duration of the Training: 4-5 weekends
Unix uses shells to accept commands given by the user, there are quite a few different shells available. The most commonly used shells are SH(Bourne SHell) CSH(C SHell) and KSH(Korn SHell), most of the other shells you encounter will be variants of these shells and will share the same syntax, KSH is based on SH and so is BASH(Bourne again shell). TCSH(Extended C SHell) is based on CSH.
The various shells all have built in functions which allow for the creation of shell scripts, that is, the stringing together of shell commands and constructs to automate what can be automated in order to make life easier for the user.
UNIX is the oldest and most secure operating system present today. UNIX architecture is definitely more robust, secure and reliable than that of Windows, All Linux distributions, Free BSD, HP-UX by HP, AIX by IBM, Solaris by Oracle, and Mac OSX by Apple are purely UNIX based operating systems.
