NAME
File::Spec::VMS - methods for VMS file specs
SYNOPSIS
require File::Spec::VMS; # Done internally by File::Spec if needed
DESCRIPTION
See File::Spec::Unix for a documentation of the methods provided there.
This package overrides the implementation of these methods, not the
semantics.
The default behavior is to allow either VMS or Unix syntax on input and
to return VMS syntax on output unless Unix syntax has been explicitly
requested via the "DECC$FILENAME_UNIX_REPORT" CRTL feature.
canonpath (override)
Removes redundant portions of file specifications and returns
results in native syntax unless Unix filename reporting has been
enabled.
catdir (override)
Concatenates a list of file specifications, and returns the result
as a native directory specification unless the Unix filename
reporting feature has been enabled. No check is made for
"impossible" cases (e.g. elements other than the first being
absolute filespecs).
catfile (override)
Concatenates a list of directory specifications with a filename
specification to build a path.
curdir (override)
Returns a string representation of the current directory: '[]' or
'.'
devnull (override)
Returns a string representation of the null device: '_NLA0:' or
'/dev/null'
rootdir (override)
Returns a string representation of the root directory:
'SYS$DISK:[000000]' or '/'
tmpdir (override)
Returns a string representation of the first writable directory from
the following list or '' if none are writable:
/tmp if C<DECC$FILENAME_UNIX_REPORT> is enabled.
sys$scratch:
$ENV{TMPDIR}
If running under taint mode, and if $ENV{TMPDIR} is tainted, it is
not used.
updir (override)
Returns a string representation of the parent directory: '[-]' or
'..'
case_tolerant (override)
VMS file specification syntax is case-tolerant.
path (override)
Translate logical name DCL$PATH as a searchlist, rather than trying
to "split" string value of $ENV{'PATH'}.
file_name_is_absolute (override)
Checks for VMS directory spec as well as Unix separators.
splitpath (override)
($volume,$directories,$file) = File::Spec->splitpath( $path );
($volume,$directories,$file) = File::Spec->splitpath( $path,
$no_file );
Passing a true value for $no_file indicates that the path being
split only contains directory components, even on systems where you
can usually (when not supporting a foreign syntax) tell the
difference between directories and files at a glance.
splitdir (override)
Split a directory specification into the components.
catpath (override)
Construct a complete filespec.
abs2rel (override)
Attempt to convert an absolute file specification to a relative
specification.
rel2abs (override)
Return an absolute file specification from a relative one.
