NAME

File::Stat::ModeString - conversion file stat(2) mode to/from string representation.

SYNOPSIS

 use File::Stat::ModeString;

 $string  = mode_to_string  ( $st_mode );
 $st_mode = string_to_mode  ( $string  );
 $type    = mode_to_typechar( $st_mode );

 $record = <IN>; chomp $record;
 $record =~ m/^some_prefix\s+$MODE_STRING_RE\s+some_suffix$/o
        or die "invalid record format";

 die "Invalid mode in $string"
        if is_mode_string_valid( $string );

DESCRIPTION

This module provides a few functions for conversion between binary and literal representations of file mode bits, including file type.

All of them use only symbolic constants for mode bits from File::Stat::Bits.

CONSTANTS

$MODE_STRING_RE

Regular expression to match mode string (without ^$).

FUNCTIONS

is_mode_string_valid( $string )

Returns true if argument matches mode string pattern.

$type = mode_to_typechar( $mode )

Returns file type character of binary mode, '?' on unknown file type.

$string = mode_to_string( $mode )

Converts binary mode value to string representation. '?' in file type field on unknown file type.

$mode = string_to_mode( $string )

Converts string representation of file mode to binary one.

SEE ALSO

stat(2);

File::Stat::Bits(3);

Stat::lsMode(3);
