READLINK(1) BSD Reference Manual READLINK(1)
readlink - display target of symbolic link or realpath on standard
readlink [-fn] file
The readlink 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 is in- voked with an argument other than the pathname of a symbolic link, it ex- its with a nonzero exit code without printing anything. The options are as follows: -f 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. -n Do not print a trailing newline character. The readlink utility exits 0 on success or >0 if an error occurred.
The readlink utility first appeared in OpenBSD 2.1. MirOS BSD #10-current August 18, 1997 1
