String Manipulation Functions: Write a Bash script that defines functions for common string manipulations such as string length, substring extraction, and string concatenation. Pass strings as arguments to these functions. Code: #!/bin/bash # Function to get the length of a string string_length()...

Instead, Bash functions work like shell commands and expect arguments to be passed to them in the same way one might pass an option to a shell command (e.g.ls -l). In effect,function argumentsin Bash are treated aspositional parameters($1, $2..$9, ${10}, ${11}, and so on). ...

1. A function is read directly into the shell's memory and stored for later use. Since computer memory is not an issue nowadays, using functions isfasterthan repeating code. 2. Functions help organize long shell scripts into modular and reusable code blocks. The chunks areeasier to develop ...
