Not necessarily a concern, because quoting (part of) the command name (e.g., \unalias) bypasses aliases. Having them redefined as shell functions in a manner that alters their behavior would be a problem redefinition as an alias is The function relies on unalias and unset having their original meaning.

That POSIX-like shells allow redefinition of builtins and even language keywords is inherently a security risk (and writing paranoid code is hard in general).

There is something that the function must rely on to have its original meaning and behavior - there is no way around that. I think it's safe to say that unless you're dealing with an untrusted, malicious environment, worrying about unalias or unset - or, for that matter, while, do. The motivation behind rreadlink ensuring that command has its original meaning is to use it to bypass (benign) convenience aliases and functions often used to shadow standard commands in interactive shells, such as redefining ls to include favorite options. What if unalias or unset and [ are set as aliases or shell functions? Jarno, in reference to the function ensuring that builtin command is not shadowed by an alias or shell function of the same name, asks in a comment: However, if it might be a file, then this won't work: DIR=$(cd $(dirname "$FILE") pwd -P) echo "$/$fname" Is your path a directory, or might it be a file? If it's a directory, it's simple: (cd "$DIR" pwd -P) Perl -MCwd -le 'print Cwd::abs_path(shift)' "$path" Use the following perl command on OS X to fill the gap of the missing readlink -f functionality:
#Bash shell for windows 10 ln link symbolic link mac os x
realpath $pathįor Mac OS X (through at least 10.11.x), use readlink without the -f option: readlink $pathĮditor's note: This will not resolve symlinks recursively and thus won't report the ultimate target e.g., given symlink a that points to b, which in turn points to c, this will only report b (and won't ensure that it is output as an absolute path). It also includes functionality to generate a relative path between two files.

It's also compatible with the FreeBSD util of the same name. Note since GNU coreutils 8.15 (), there is a realpath program available that is less obtuse and more flexible than the above. GNU readlink offers additional, related options, such as -m for resolving a symlink whether or not the ultimate target exists. Editor's note: The above works with GNU readlink and FreeBSD/PC-BSD/OpenBSD readlink, but not on OS X as of 10.11.
