shift

shift

 [

variable

]

If variable is given, shift the words in a wordlist variable; i.e., name [2] becomes name [1] . With no argument, shift the positional parameters (command-line arguments); i.e., $2 becomes $1 . shift is typically used in a while loop. See additional example under while .

Example

while ($#argv)      # while there are arguments     if (-f $argv[1])          wc -l $argv[1]     else        echo "$argv[1] is not a regular file"     endif     shift           # get the next argument end
