Passing Arguments to the Script
Arguments can be passed to the script when it is executed, by writing them as a space-delimited list following the script file name.
Arguments can be passed to the script when it is executed, by writing them as a space-delimited list following the script file name.
Inside the script, the $1 variable references the first argument in the command line, $2 the second argument and so forth. The variable $0 references to the current script. In the following example, the script name is followed by 6 arguments.
./bin/my_shopping.sh apple 5 banana 8 “Fruit Basket” 15
echo $3 –> results with: banana
BIG=$5
echo “A $BIG costs just $6” –> results with: A Fruit Basket costs just 15
The variable $# holds the number of arguments passed to the script
echo $# –> results with: 6
The variable $@ holds a space delimited string of all arguments passed to the script
