Shift

The shift command in shell scripting renames the command-line arguments. Specifically, it moves each argument one position to the left. The value of $2 becomes $1, the value of $3 becomes $2, and so on. The original value of $1 is lost. This is particularly useful when you need to process a variable number of arguments passed to a script.
