NAME
pathchk — check path names
DESCRIPTION
The
pathchk
command checks that one or more path names
are valid and portable.
By default, the
pathchk
command checks each component of each path name
specified by the
pathname
parameter based on the underlying file system.
An error message is written for each path name operand that:
is longer than that allowed by the system.
contains any component longer than that allowed by the system.
contains any component in a directory that is not searchable.
contains any character in any component that is not valid in its
containing directory.
It is not considered an error if
one or more components of a path name do not exist,
as long as a file matching the path name
specified by the
pathname
parameter could be created that does
not violate any of the checks above.
More extensive portability checks are performed when the
-p
flag is specified.
Options
The
pathchk
command supports the following option:
- -p
Performs path name checks based on
POSIX portability standards instead of the
underlying file system.
An error message is written for each path name that:
is longer than
_POSIX_PATH_MAX
bytes.
contains any component longer than
_POSIX_NAME_MAX
bytes.
contains any character in any component
that is not in the portable file name character set.
EXTERNAL INFLUENCES
Environment Variables
LC_MESSAGES
determines the language in which messages are displayed.
If
LC_MESSAGES
is not specified in the environment or is set to
the empty string, the value of
LANG
is used as a default for each
unspecified or empty variable.
If
LANG
is not specified or is set to the empty string, a default of "C" (see
lang(5))
is used instead of
LANG.
If any internationalization variable contains an invalid setting,
pathchk
behaves as if all internationalization variables are set to "C".
See
environ(5).
International Code Set Support
Single-byte and multi-byte character code sets are supported.
RETURN VALUE
Upon successful completion,
pathchk
returns zero; otherwise it returns nonzero to indicate an error.
EXAMPLES
To check the validity and portability of the
/users/mary/work/tempfiles
path name on your system, use:
pathchk /users/mary/work/tempfiles
To check the validity and portability of the
path name for POSIX standards, use:
pathchk -p /users/mary/temp
STANDARDS CONFORMANCE
pathchk: XPG4, POSIX.2
