COBOL vs GNU Bash: What are the differences?

## Introduction

The Key differences between COBOL and GNU Bash are as follows:

1. **Language Type**: COBOL is a high-level programming language used in business applications, focusing on data processing and reports, whereas GNU Bash is a command line interpreter for Unix-like operating systems.
2. **Syntax**: COBOL uses a verbose and English-like syntax, making it easier for non-programmers to understand, while GNU Bash has a concise syntax with a focus on commands and scripting.
3. **Usage**: COBOL is mainly used in legacy systems for large-scale business applications, such as banking and finance, while GNU Bash is preferred for system administration, automation tasks, and shell scripting.
4. **Variables**: COBOL uses data structures and record definitions extensively for working with data, while GNU Bash primarily focuses on simple variable declarations and manipulations.
5. **Control Structures**: COBOL supports traditional procedural programming constructs like loops and conditional statements, while GNU Bash provides shell scripting features like piping, redirection, and command substitution for task automation.
6. **Portability**: COBOL programs are less portable due to system-specific dependencies, whereas GNU Bash scripts can easily run on different Unix-like systems with minimal modifications.

In Summary, COBOL and GNU Bash differ in language type, syntax, usage, variables, control structures, and portability, catering to different programming needs and environments.

If you have a file (demo.txt) that has 3 columns:

Column-1    Column-2    Column-3
Row-1a      Row-2a      Row-3a         
Row-1b      Row-2b      Row-3b
Row-1c      Row-2c      Row-3c
Row-1d      Row-2d      Row-3d
Row-1e      Row-2e      Row-3e

and you want to only view the first column of the file in your CLI, run the following:

awk {'print $1'} demo.txt

Column-1
Row-1a
Row-1b
Row-1c
Row-1d
Row-1e

If you want to print the second column of demo.txt, just replace $1 with $2

What is COBOL?

COBOL was one of the first programming languages to be standardised: the first COBOL standard was issued by ANSI in 1968. COBOL is primarily used in business, finance, and administrative systems for companies and governments.

What is GNU Bash?

The Bourne Again SHell is an sh-compatible shell that incorporates useful features from the Korn shell (ksh) and C shell (csh). It is intended to conform to the IEEE POSIX P1003.2/ISO 9945.2 Shell and Tools standard.

What are some alternatives to COBOL and GNU Bash?
Python
Python is a general purpose programming language created by Guido Van Rossum. Python is most praised for its elegant syntax and readable code, if you are just beginning your programming career python suits you best.
Java
Java is a programming language and computing platform first released by Sun Microsystems in 1995. There are lots of applications and websites that will not work unless you have Java installed, and more are created every day. Java is fast, secure, and reliable. From laptops to datacenters, game consoles to scientific supercomputers, cell phones to the Internet, Java is everywhere!
