p A diagnostic message is written for each argument that: l -bullet t Is longer than .Dv PATH_MAX bytes. t Contains any component longer than .Dv NAME_MAX bytes. (The value of .Dv NAME_MAX depends on the underlying file system.) t Contains a directory component that is not searchable. .El
p It is not considered an error if a .Ar pathname argument contains a nonexistent component as long as a component by that name could be created.
p The options are as follows: l -tag -width indent t Fl p Perform portability checks on the specified .Ar pathname arguments. Diagnostic messages will be written for each argument that: l -bullet t Is longer than .Dv _POSIX_PATH_MAX
q 255 bytes. t Contains a component longer than .Dv _POSIX_NAME_MAX
q 14 bytes. t Contains any character not in the portable filename character set (that is, alphanumeric characters, .Ql . , .Ql - and .Ql _ ) . No component may start with the hyphen
q Ql - character. .El t Fl P In addition to the default or .Fl p checks, write a diagnostic for each argument that: l -bullet t Is empty. t Contains a component that starts with a hyphen. .El .El .Sh EXIT STATUS .Ex -std .Sh EXAMPLES Check whether the names of files in the current directory are portable to other .Tn POSIX systems:
p .Dl "find . -exec pathchk -p -- {} +" .Sh SEE ALSO .Xr getconf 1 , .Xr pathconf 2 , .Xr stat 2 .Sh STANDARDS The .Nm utility conforms to .St -p1003.1-2001 . .Sh HISTORY A .Nm utility appeared in .Fx 5.0 .
