readline EXPR readline Reads from the filehandle whose typeglob is contained in EXPR (or from *ARGV if EXPR is not provided). In scalar context, each call reads and returns the next line until end-of-file is reached, whereupon the subsequent call returns undef. In list context, reads until end-of-file is reached and returns a list of lines. Note that the notion of "line" used here is whatever you may have defined with $/ or $INPUT_RECORD_SEPARATOR ). See $/ in perlvar. When $/ is set to undef,

package NAMESPACE package NAMESPACE VERSION package NAMESPACE BLOCK package NAMESPACE VERSION BLOCK Declares the BLOCK or the rest of the compilation unit as being in the given namespace. The scope of the package declaration is either the supplied code BLOCK or, in the absence of a BLOCK, from the declaration itself through the end of current scope (the enclosing block, file, or eval). That is, the forms without a BLOCK are operative through the end of the current scope, just like the my, state

$] The revision, version, and subversion of the Perl interpreter, represented as a decimal of the form 5.XXXYYY, where XXX is the version / 1e3 and YYY is the subversion / 1e6. For example, Perl v5.10.1 would be "5.010001". This variable can be used to determine whether the Perl interpreter executing a script is in the right range of versions: warn "No PerlIO!\n" if $] lt '5.008'; When comparing $] , string comparison operators are highly recommended. The inherent limitations of binary floati

NAME SYNOPSIS ABSTRACT DESCRIPTION SEE ALSO NAME Encode::Byte - Single Byte Encodings SYNOPSIS use Encode qw/encode decode/; $greek = encode("iso-8859-7", $utf8); # loads Encode::Byte implicitly $utf8 = decode("iso-8859-7", $greek); # ditto ABSTRACT This module implements various single byte encodings. For most cases it uses \x80-\xff (upper half) to map non-ASCII characters. Encodings supported are as follows. Canonical Alias Description ----------------------

pop ARRAY pop EXPR pop Pops and returns the last value of the array, shortening the array by one element. Returns the undefined value if the array is empty, although this may also happen at other times. If ARRAY is omitted, pops the @ARGV array in the main program, but the @_ array in subroutines, just like shift. Starting with Perl 5.14, pop can take a scalar EXPR, which must hold a reference to an unblessed array. The argument will be dereferenced automatically. This aspect of pop is consider

chmod LIST Changes the permissions of a list of files. The first element of the list must be the numeric mode, which should probably be an octal number, and which definitely should not be a string of octal digits: 0644 is okay, but "0644" is not. Returns the number of files successfully changed. See also oct if all you have is a string. $cnt = chmod 0755, "foo", "bar"; chmod 0755, @executables; $mode = "0644"; chmod $mode, "foo"; # !!! sets mode to

close FILEHANDLE close Closes the file or pipe associated with the filehandle, flushes the IO buffers, and closes the system file descriptor. Returns true if those operations succeed and if no error was reported by any PerlIO layer. Closes the currently selected filehandle if the argument is omitted. You don't have to close FILEHANDLE if you are immediately going to do another open on it, because open closes it for you. (See open.) However, an explicit close on an input file resets the line cou

time Returns the number of non-leap seconds since whatever time the system considers to be the epoch, suitable for feeding to gmtime and localtime. On most systems the epoch is 00:00:00 UTC, January 1, 1970; a prominent exception being Mac OS Classic which uses 00:00:00, January 1, 1904 in the current local time zone for its epoch. For measuring time in better granularity than one second, use the Time::HiRes module from Perl 5.8 onwards (or from CPAN before then), or, if you have gettimeofday(2

uc EXPR uc Returns an uppercased version of EXPR. This is the internal function implementing the \U escape in double-quoted strings. It does not attempt to do titlecase mapping on initial letters. See ucfirst for that. If EXPR is omitted, uses $_ . This function behaves the same way under various pragma, such as in a locale, as lc does.
