realpath

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/bin.
Than

realpath /../usr/bin/X11/./xterm

prints

/usr/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.
