3.2.163 symlink


This function creates a new filename symbolically linked to the old filename. The function returns 1 for success, 0 otherwise. On systems that don't support symbolic links, it produces a fatal error at run-time. To check for that, use eval to trap the potential error:

$can_symlink = (eval { symlink("", ""); }, $@ eq "");

Or use the Config module. Be careful if you supply a relative symbolic link, since it'll be interpreted relative to the location of the symbolic link itself, not your current working directory.

See also link and readlink earlier in this chapter.
