NAME

       pathchk - Checks path names

SYNOPSIS

       pathchk [-p] pathname...

STANDARDS

       Interfaces documented on this reference page conform to industry standards as follows:

       pathchk:  XCU5.0

       Refer to the standards(5) reference page for more information about industry standards and associated tags.

OPTIONS

       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.

OPERANDS

       The path name to be checked.

DESCRIPTION

       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 syn-
       tax 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.

EXAMPLES

       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

ENVIRONMENT VARIABLES

       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.

FILES

       System maximum values

EXIT STATUS

       The pathchk command returns the following exit values: All path name operands passed the checks.  An error occurred.

NAME

       pathchk - check path names

SYNOPSIS

       pathname...

DESCRIPTION

       The  command  checks  that  one or more path names are valid and portable.  By default, the 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:

	      o  is longer than that allowed by the system.

	      o  contains any component longer than that allowed by the system.

	      o  contains any component in a directory that is not searchable.

	      o  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 flag is specified.

   Options
       The command supports the following option:

	      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:

			   o  is longer than bytes.

			   o  contains any component longer than bytes.

			   o  contains any character in any component that is not in the portable file name character set.

EXTERNAL INFLUENCES

   Environment Variables
       determines the language in which messages are displayed.

       If is not specified in the environment or is set to the empty string, the value of is used as a default for each unspecified or empty vari-
       able.  If is not specified or is set to the empty string, a default of "C" (see lang(5)) is used instead of

       If any internationalization variable contains an invalid setting, 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, returns zero; otherwise it returns nonzero to indicate an error.

       path name on your system, use:
