NAME
pathchk —
check pathnames
SYNOPSIS
pathchk |
[-p] pathname
... |
DESCRIPTION
The
pathchk utility checks whether each of the specified
pathname arguments is valid or portable.
A diagnostic message is written for each argument that:
- Is longer than
PATH_MAX
bytes.
- Contains any component longer than
NAME_MAX
bytes. (The value of
NAME_MAX
depends on the underlying file
system.)
- Contains a directory component that is not
searchable.
It is not considered an error if a
pathname argument
contains a nonexistent component as long as a component by that name could be
created.
The options are as follows:
-
-
- -p
- Perform portability checks on the specified
pathname arguments. Diagnostic messages will be
written for each argument that:
- Is longer than
_POSIX_PATH_MAX
(255) bytes.
- Contains a component longer than
_POSIX_NAME_MAX
(14) bytes.
- Contains any character not in the portable filename
character set (that is, alphanumeric characters,
‘
.
’,
‘-
’ and
‘_
’). No component may start with
the hyphen (‘-
’) character.
EXAMPLES
Check whether the names of files in the current directory are portable to other
POSIX systems:
find . -exec pathchk -p \{\} +
or the more efficient:
find . -print0 | xargs -0 pathchk
-p
