Synopsis
if (condition)statement1[elsestatement2]
If condition is true, do
statement1; otherwise, do
statement2 in optional else clause. The
condition can be an expression using any of
the relational operators <,
<=, ==, !=, >=, or >, as well as the array membership
operator in, and the
pattern-matching operators ~
and !~ (e.g., if ($1 ~ /[Aa].*/)). A series of
statements must be put within braces. Another if can directly follow an else in order to produce a chain of
tests or decisions.
