  1. 1BASH is two things.
    1. U[blank_start]nix[blank_end] S[blank_start]hell[blank_end] (s[blank_start]hell[blank_end] around u[blank_start]nix[blank_end] like O[blank_start]S[blank_end], CLI)
    2. command line [blank_start]language[blank_end] for Shell (shell is [blank_start]program[blank_end] around O[blank_start]S[blank_end])
    3. Is default login shell for most Linux and mac OSx. Makes sense as Linux and mac OSx operating systems are branch of u[blank_start]nix[blank_end] os and BASH is shell [blank_start]program[blank_end] for u[blank_start]nix[blank_end]-like O[blank_start]S[blank_end].

    Shell is a user i[blank_start]nterface[blank_end] p[blank_start]rogram[blank_end] for accessing Operating System's s[blank_start]ervices[blank_end]. In general OS shells use either CLI or GUI.
    This program for accessing operating system's services is named shell because it is the o[blank_start]uter[blank_end]most layer around K[blank_start]ernel[blank_end]. Kernel is c[blank_start]ore[blank_end] p[blank_start]rogram[blank_end] of o[blank_start]perating[blank_end] system. It is a program, with complete control over everything in the system. It is the [blank_start]first[blank_end] program loaded in s[blank_start]tart[blank_end]up. It handles input/outputs r[blank_start]equest[blank_end]s from s[blank_start]oftware[blank_end](application) translating them into data processing instructions for CPU to execute, or handles RAM or devices like mouses/keyboards.
    Application --> [ Kernel or OS ] --> CPU || Memory/RAM || Devices/mouses/keyboards
    Everything that CPU/Memory RAM/Devices handles is g[blank_start]iven[blank_end] from K[blank_start]ernel[blank_end] Program that is c[blank_start]ore[blank_end] of Operating system.
    UNIX is [blank_start]operating[blank_end] system.
    Nearly all operating systems traces its heritage back to [blank_start]unix[blank_end] operating system.
    This is list of unix -like operating systems.
    1. L[blank_start]inux[blank_end]
    2. M[blank_start]ac[blank_end] OS
    3. A[blank_start]ndroid[blank_end]
    4. i[blank_start]os[blank_end]
    5. C[blank_start]hrome[blank_end] OS

    Both Batch and Bash is type of shell p[blank_start]rogram[blank_end] and command line l[blank_start]anguage[blank_end] for shell.
    Bash and Batch shell programs are also command p[blank_start]rocessor[blank_end]s for user typed commands that causes actions.
    Bash and Batch programs can also r[blank_start]ead[blank_end] and e[blank_start]xecute[blank_end] commands from a file called a [blank_start]script[blank_end]. This is called [blank_start]script[blank_end], because it is written in s[blank_start]cripting[blank_end] l[blank_start]anguage[blank_end]. Bash and Batch is also command line language to itself, which is considered scripting language. What is scripting language? Scripting language is program language that supports scripts: programs written for special [blank_start]run[blank_end]-time [blank_start]environment[blank_end] that automate execution of tasks, that could be executed bone by one by a human operator. Scripting languages are often i[blank_start]nterpreted[blank_end] languages, meaning they can run in run-time, or c[blank_start]ompiles[blank_end] and e[blank_start]xecutes[blank_end] BOTH in run time, and doesn't compile the whole source code b[blank_start]efore[blank_end] execution (run time). Meaning there is [blank_start]no[blank_end] compile phase [blank_start]before[blank_end] execution (run time). B[blank_start]oth[blank_end] compilation and execution happen in run time (execution). Scripting languages or interpreted languages does not have separate compile phase before run time or execution. It all happens at the s[blank_start]ame[blank_end] time, line by line at [blank_start]run[blank_end] time.

    Bash and Batch like all unix shell programs, supports filename globbing, wildcard matching , piping etc.
