The arguments are stored in variables with a number in the order of the argument starting at 1
- First Argument: $1
- Second Argument: $2
- Third Argument: $3
- command: ./script.bash alpha beta gamma
- Variables: $1=='alpha'; $2=='beta'; $3=='gamma'
The variable $0 is the script's name. The total number of arguments is stored in $#. The variables $@ and $* return all the arguments.
For more complicated examples, you might consider getopt: http://aplawrence.com/Unix/getopts.html
#!/bin/bash echo "the $1 eats a $2 every time there is a $3" echo "bye:-)"
- Command: ./script.bash dog bone moose
