METHODS

min(float $first, float $second [, float $third ...] )

max(float $first, float $second [, float $third ...] )

Determine the minimum or maximum numeric value out of several.

inhibit(bool $first, bool $second)

Calculates the logical inhibition of two values, defined as ((not $a) and $b).

toggle(bool ref $arg)

triggle(int ref $arg)

Determine the next value in a cyclic two/three-state system.

isxterm(string $termname)

Determines if a certain value for $ENV{TERM} is compatible with 'xterm'.

isyes(string $yesno)

isno(string $yesno)

Determine if a certain string value is equivalent to boolean false or true.

dirname(string $path)

basename(string $path)

Determine the filename without directory (basename) or directoryname containing the file (dirname) for the specified path.

formatted( [ $field1 [, $field2 [, ... ] ] ] )

Returns a line that has been formatted using Perl formatting algorithm.

fit2limit(int $number, int $limit)

Fits a file size into a certain number of characters by converting it to a number with kilo (mega, giga, ...) specification.

canonicalize_path(string $path [, bool $keeptrail ] )

Turns a directory path into a canonical path (like realpath()), but does not resolve symlinks.

If keeptrail is set, a trailing . or .. component is left untouched.

reducepaths(string $firstpath, string $secondpath )

Removes an identical prefix from two paths.

reversepath(string $symlink_target_abs, string $symlink_name_rel)

Reverses the path from target to symlink, i.e. returns the path from symlink to target.

isorphan(string $symlinkpath)

Returns true if a symlink is an orphan symlink.

ifnotdefined(mixed $first, mixed $second)

Emulates the perl 5.10 "//" operator (returns the first argument if it is defined, otherwise the second).

setifnotdefined(mixed ref $var, mixed $value)

Emulates the perl 5.10 "//=" operator (if the first argument is undefined, it is set to the value of the second).

clearugidcache()

Clears the username/groupname cache.

find_uid(int $uid)

find_gid(int $gid)

Finds the username or group name corresponding to a uid or gid, and caches the result.

condquotemeta(bool $do_quote, string $text)

Conditionally quotemeta() a string.

touch2time(string $datetime)

Parses a datetime string of the format [[CC]YY-]MM-DD hh:mm[.ss] and returns a datetime integer as created by mktime(3).

testdirempty(string $dirpath)

Tests if a directory is empty.

fitpath(string $path, int $maxlength)

Fits a path string to a certain length by taking out directory components.

alphabetically()

Sorting routine: sorts strings alphabetically, case-insensitive.

letters_then_numbers()

Sorting routine: sorts strings alphabetically, case-insensitive, but numbers last.

by_name()

Sorting routine: sorts files by name.

lstrftime(string $format, array @datetime)

Formats a date/time string.
