Bash Scripting

Arguments

Arguments are keywords that are passed in the command line when executing the bash script/command.

./script.sh foo bar

$0, $1, $2 etc..

$0 is the name of the script
$1 is the first argument, $2 is the second argument and so on.

Arguments passed at the time of script execution and taking user input with read oth serve the same purpose. read is a bit more safe for noobs.
