BASH

 

·         Readability

 

Bash used “if”, “fi” statements for separating and to increase the readability of the language. These statements were helpful when using nested if statements. Also, bash ignores whitespaces at the start of a line, therefore indentations are not crucial, but it can be used to improve the readability. Furthermore, readability of bash scripting language was improved with the implementation of “;”, since it can be used to identify commands separately and a newline being created after then, else statements also help to identify commands separately.

 

·         Writability

 

The factors affecting readability also affects writability as a result, Bash’s writability was in an improved standard. Bash data types are untyped which means we only need to type the variable name and the value. Also, the writability of bash was improved by letting use of functions in bash which also supports abstraction.

 

·         Reliability

 

Bash scripting language has increased its reliability by implementing its type checking during run time. Also, bash doesn’t handle or throw exception since bash scripting language is not designed to handle exceptions which affects the reliability of this scripting language. Furthermore, bash scripting language has shellcheck to check for errors during the development process which increases the reliability of the language.
