pathchk [-p] pathname...
Interfaces documented on this reference page conform to industry standards as follows:
pathchk: XPG4, XPG4-UNIX
Refer to the
standards(5)
reference page for more information
about industry standards and associated tags.
Performs path name checks based on POSIX portability standards.
An error message is sent if any of the following conditions are true:
The byte length of the full path name is longer than allowed
by POSIX standards ({_POSIX_PATH_MAX}).
The byte length of a component is longer than allowed by POSIX
standards ({_POSIX_NAME_MAX}).
A character in any component is not in the portable file name
character set.
The pathchk command checks that one or more path names are valid (that is, they can be used to access or create a file without causing syntax errors) and portable (that is, no file name truncation will result).
By default, the pathchk command checks each component of each path name specified by the pathname argument based on the underlying file system. If the -p option is not specified, pathchk sends an error message if any of the following conditions are true: The byte length of the full path name is longer than allowed by the system ({PATH_MAX} bytes). The byte length of a component is longer than allowed by the system ({NAME_MAX} bytes). Search permission is not allowed for a component. A character in any component 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
argument could be created without violating any of
the preceding criteria.
To check the validity and portability of the /u/bob/work/tempfiles path name, enter: pathchk /u/bob/work/tempfiles To check the validity and portability of the /u/bob/temp path name for POSIX standards, enter: pathchk -p /u/bob/temp
The following environment variables affect the execution of
pathchk:
Provides a default value for the internationalization variables
that are unset or null. If
LANG
is unset or null, the corresponding value from the default locale is used.
If any of the internationalization variables contain an invalid setting, the
utility behaves as if none of the variables had been defined.
If set to a non-empty string value, overrides the values of
all the other internationalization variables.
Determines the locale for the interpretation of sequences
of bytes of text data as characters (for example, single-byte as opposed to
multibyte characters in arguments).
Determines the locale for the format and contents of diagnostic
messages written to standard error.
Determines the location of message catalogues for the processing
of
LC_MESSAGES.
The pathchk command returns the following exit values:
All path name operands passed the checks.
An error occurred.
