Followed by the path to the shell, in this case bash - this acts as an interpreter directive and ensures that the script is executed under the correct shell. The # character indicates a comment, so the shebang line is ignored by bash when running the script. Learn the Shell scripting by example on various platforms like Linux, Mac OS X as well as different flavors of Linux distribution like Fedora, Redhat, Suse, CentoS etc. Take each isolated script and go through various parts and understand the nitty gritty of the scripts and how to efficiently join them to make a functional script. Write shell scripts that can be used on Linux, Mac, and Unix operating systems. Automate tasks using shell scripts. Create complex scripts that take advantage of advanced bash shell features.
Bash is the GNU Project's shell—the Bourne Again SHell.This is an sh-compatible shell thatincorporates useful features from the Korn shell (ksh) and the C shell(csh). It is intended to conform to the IEEE POSIX P1003.2/ISO 9945.2Shell and Tools standard. It offers functional improvements over shfor both programming and interactive use. In addition, most sh scriptscan be run by Bash without modification.
The improvements offered by Bash include:
- command-line editing,
- unlimited size command history,
- job control,
- shell functions and aliases,
- indexed arrays of unlimited size,
- integer arithmetic in any base from two to sixty-four.
