There is no single command to convert a symlink to a regular file. The most direct way is to use readlink to find the file a symlink points to, and then copy that file over the symlink: cp –remove-destination `readlink bar.pdf` bar.pdf Of course, if bar.pdf is, in fact, a regular file to begin with, … Read more
The ls -l command will show you that: $ ls -l foo lrwxrwxrwx 1 user group 11 2010-12-31 19:49 foo -> /etc/passwd Or the readlink command: $ readlink foo /etc/passwd So, the symbolic link foo points to the path /etc/passwd.
Docker doesn’t support symlinking files outside the build context. Here are some different methods for using a shared file in a container: Build Time Copy from a config image (Docker buildkit) Recent versions of Docker allow RUN steps to bind mount from a named image or previous build stage with the –mount=type=bind,target=/dir,source=/dir,from=image-or-stage-name Create a Dockerfile … Read more
I’d use the find command. find . -lname /particular/folder That will recursively search the current directory for symlinks to /particular/folder. Note that it will only find absolute symlinks. A similar command can be used to search for all symlinks pointing at objects called “folder”: find . -lname ‘*folder’ From there you would need to weed … Read more
This seems to be a better idea find . -type l | sed -e s’/^\.\///g’ >> .gitignore Find outputs a “./” prefix for all files. Unless you trim it off, gitignore is unable to act on them . Once you trim the “.\” at the beginning , it works like a charm
Here’s a POSIX way of deleting all broken symbolic links in the current directory, without recursion. It works by telling find to traverse symbolic links (-L), but stopping (-prune) at every directory-or-symbolic-link-to-such. find -L . -name . -o -type d -prune -o -type l -exec rm {} + You can also use a shell loop. … Read more
os.path.realpath(path) os.path.realpath returns the canonical path of the specified filename, eliminating any symbolic links encountered in the path.
You could create the new link with a different name, then move it to replace the old link. ln -s /location/to/link linkname Later ln -s /location/to/link2 newlink mv newlink linkname If newlink and linkname are on the same physical device the mv should be atomic.
The standard File module has the usual file tests available: RUBY_VERSION # => “1.9.2” bashrc = ENV[‘HOME’] + ‘/.bashrc’ File.exist?(bashrc) # => true File.file?(bashrc) # => true File.directory?(bashrc) # => false You should be able to find what you want there. OP: “Thanks but I need all three true or false” Obviously not. Ok, try … Read more
Check the man page again 😉 It’s: find /path/to/files -type f type f searches for regular files only – excluding symbolic links.
