for Explanation The keyword for is used in a shell script to begin a loop that iterates over a list of items or a range of numbers.
The syntax of the for loop is as follows:
for <var> in <list> do <commands> done
The variable <var> is assigned to each element of the <list> in turn, and the <commands> are executed for each iteration. The <list> can be a sequence of words, numbers, filenames, or other values. If the <list> is omitted, the for loop will iterate over the positional parameters ($1, $2, ...). The do and done keywords mark the beginning and the end of the loop body, respectively. The for loop is one of the three types of loops in shell scripting, along with the while and until loops.
