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 is faster than repeating code. 2. Functions help organize long shell scripts into modular and reusable code blocks. The chunks are easier to devel...

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). ...
Inside the function: Declare a local variable 'num' to store the argument passed to the function. Declare another local variable 'result' and initialize it to 1. Check if 'num' is negative. If it is, we print an error message and exit the script. ...
I am searching for methods to pass the value of arguments to a script obtained from git using curl, while also needing an argument for my script. Is it possible to pass arguments to the script in the following manner: bash <(curl -Ls) ...
Passing arguments to bash function You can pass arguments to a function just like you can pass arguments to a bash script. You just include the arguments when you do the function call. To demonstrate, let’s take a look at the following iseven.sh bash script: #!/bin/bash iseven () ...
3. Passing arguments to bash script You can pass arguments to a bash script while running it in the following manner: ./my_script.sh arg1 arg2 Inside the script, you can use $1 for the 1st argument, $2 for the 2nd argument and so on. $0 is a special variable that holds the name...
In the same way we can use exit to terminate a script, we can use the return command to exit a function and return an exit code to the caller. You can use exit inside a function too and this will exit the function and terminate the program....
/* Return the event specified at TEXT + OFFSET modifying OFFSET to point to after the event specifier. Just a pointer to the history line is returned; NULL is returned in the event of a bad specifier. You pass STRING with *INDEX equal to the history_expansion_char that ...
