What is a Foreach?

Foreach may refer to any of the following:

1.Foreach is a loop statement in programming that performs predefined tasks while or until a predetermined condition is met.

For example, in Perl you can use a foreach loop that prints all the elements of an array one by one. Sample code:

Foreach on array in Perl
foreach $value (@value) {
print "$value\n";}

If the elements of the array was "one," "two," and "three" each would be printed on a new line by itself.

Foreach on hash in Perl

In the next example the foreach would step through a hash displaying the hash and the key value.

foreach $example (keys %value) {
print "$example = $value{$example}";
}

2.Foreach is also a Linux command, see the foreach command page for further information.
