display target of symbolic link on standard
utility when invoked with the pathname
of a symbolic link as its argument dereferences the symbolic link and prints
the name of target on standard output. If the -f
option is not specified and readlink
with an argument other than the pathname of a symbolic link, it exits with a
nonzero exit code without printing anything.
The options are as follows:
- Canonicalize by following every symlink in every component
of the given path recursively. readlink will
resolve both absolute and relative paths and return the absolute pathname
corresponding to file. The argument does
not need to be a symbolic link.
- Do not print a trailing newline character.
utility exits 0 on success,
and >0 if an error occurs.
