unshift - prepend more elements to the beginning of a list
unshift
ARRAY,LIST
Does the opposite of a shift(). Or the opposite of a push(), depending on how you look at it. Prepends list to the front of the array,
and returns the new number of elements in the array.
unshift(ARGV, '-e') unless $ARGV[0] =~ /^-/;
Note the
LIST is prepended whole, not one element at a time, so
the prepended elements stay in the same order. Use reverse() to do the reverse.
DISCLAIMER
We are painfully aware that these documents may contain incorrect links and
misformatted HTML. Such bugs lie in the automatic translation process
that automatically created the hundreds and hundreds of separate documents that you find here. Please do
not report link or formatting bugs, because we cannot fix
per-document problems. The only bug reports that will help us are those
that supply working patches to the installhtml or pod2html
programs, or to the Pod::HTML module itself, for which I and the entire
Perl community will shower you with thanks and praises.
If rather than formatting bugs, you encounter substantive content errors in these documents, such as mistakes in
the explanations or code, please use the perlbug utility included
with the Perl distribution.
