man realpath (Commandes) - return the canonicalised absolute pathname

NAME

realpath - return the canonicalised absolute pathname

SYNOPSIS

realpath [-s|--strip] [-z|--zero] filename ...

realpath --h|--help

realpath --v|--version

DESCRIPTION

realpath converts each filename argument to an absolute pathname, which has no components that are symbolic links or the special . or .. directory entries. (See realpath(3) for more information.)

Please note that mostly the same functionality is provided by the `-f' option of the readlink(1) command.

If option -s is used realpath only removes . and .. directories, but not symbolic links from filename.

Each converted pathname is output to the standard output, on its own line.

OPTIONS

-s,--strip
Only strip . and .., but do not resolve symbolic links.
-z,--zero
Separate output filenames with the null character instead of newline, so it can be used with the `-0' option of xargs(1).
-h,--help
Print short usage information.
-v,--version
Show realpath's version number.

EXAMPLES



Let's suppose that /usr/bin/X11 is a symbolic link, which points to directory /usr/X11R6/bin.

Than

realpath /../usr/bin/X11/./xterm prints /usr/X11R6/bin/xterm but realpath -s /../usr/bin/X11/./xterm outputs /usr/bin/X11/xterm

EXIT STATUS

realpath returns a zero exit code when all pathnames was successfully converted.

In case of any errors (e.g. missing or unavailable directories in the path), realpath prints error message to stderr and returns a non-zero exit code.
