Dt REALPATH 1
Os
Sh NAME
Nm realpath
Nd return resolved canonical path
Sh SYNOPSIS
Nm
Op Fl eEq
Op Ar path ...
Sh DESCRIPTION
The
Nm
utility uses the
Xr realpath 3
function to resolve all symbolic links, extra
Ql /
characters and references to
Pa /./
and
Pa /../
in each
Ar path ,
and writes the result of each to standard output
followed by a newline.
If
Ar path
is absent, the current working directory
Pq Sq Pa .\&
is assumed.
Pp
With the
Fl E
option
(the default)
it is not an error for the final component
of the resolved pathname to reference a file
which does not exist.
Pp
The
Fl e
option reverses the effect of
Fl E ,
requiring the
Ar path
to resolve to an existing pathname.
Pp
If
Fl q
is specified, warnings will not be printed when
Xr realpath 3
fails.
Messages about other errors, such as bad usage, are still printed.
Pp
On error, nothing is written
to standard output for that
Ar path .
If
Fl q
was not given a diagnostic is written to standard error.
Sh EXIT STATUS
Ex -std
Any failure to resolve a
Ar path
is an error for this purpose,
the
Fl q
option is irrelevant.
Sh SEE ALSO
Xr readlink 1 ,
Xr realpath 3
Sh STANDARDS
The
Nm
utility is expected to comply with the forthcoming
edition of the POSIX standard.
To be fully POSIX compliant, applications must use
either the
Fl e
or
Fl E
option, as which of those (if in fact either, and
not some other behaviour) applies in their absence
is unspecified.
The standard requires support for only a single, mandatory,
Ar path
argument.
Sh HISTORY
The
Nm
utility first appeared in
Fx 4.3
and was imported into
Nx 10 ,
but modified to be slightly more compatible with the coreutils version,
and the proposed POSIX standard requirements.
