realpath
REALPATH(1) Debian REALPATH(1)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.)
Each path component in the filename must exist, otherwise realpath will fail and non-zero exit status will be returned.
Please note that mostly the same functionality is provided by the `-e' option of the readlink(1) command.
When the -s option is used realpath only removes the . and .. directories, but not symbolic links from filename. If the given filename
argument is relative (i.e. does not start with `/'), realpath -s prepends to it the current directory name as obtained from the getcwd(2)
system call before further processing.
Each converted pathname is output to the standard output, on its own line.
OPTIONS -s, --strip
Only strip . and .., components, 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
For the examples below let's suppose that /usr/bin/X11 is a symbolic link, pointing to directory /usr/bin.
Example 1
Regardless of what the current directory is
realpath /../usr/bin/X11/./xterm
prints
/usr/bin/xterm
but
realpath -s /../usr/bin/X11/./xterm
outputs
/usr/bin/X11/xterm
Example 2
When the current directory is /usr/bin/X11 (which is still a symbolic link to /usr/bin), the output of both
realpath ./xterm
and
realpath -s ./xterm
will be
/usr/bin/xterm
Example 3
Providing that the current directory is /home/user (and the directory exists before and during the realpath run), the command
realpath ../path/to/some/./non-existent/./directory/../or/../file
will fail with the following error
../path/to/some/./non-existent/./directory/../or/../file: No such file or directory
but
realpath -s ../path/to/some/./non-existent/./directory/../or/../file
will return
/home/path/to/some/non-existent/file
EXIT STATUS
realpath returns a zero exit code when all pathnames were 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.
