Transcribed Image Text:Exercise
Exercise 4: Repeat the example scripts, and run
them.
• Exercise 5: Write script that take two arguments,
and output the every number between from arg1 to
arg2.

Transcribed Image Text:shift
• shift is a shell builtin that operates on the positional parameters. Each time you
invoke shift, it "shifts" all the positional parameters down by one. $2 becomes
$1, $3 becomes $2, $4 becomes $3, and so on. Try this:
#!/bin/bash
echo "You start with $# positional parameters"
# Loop until all parameters are used up
while [ "$1" != "" 1; do
echo "Parameter 1 equals $1"
echo "You now have $# positional parameters"
# Shift all the parameters down by one
shift
done
