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
That is not possible and will not be implemented. Please have a look at the discussion on github issue #1676: We do not allow this because it’s not repeatable. A symlink on your machine is the not the same as my machine and the same Dockerfile would produce two different results. Also having symlinks to … Read more
# this works: rm foo # versus this, which doesn’t: rm foo/ Basically, you need to tell it to delete a file, not delete a directory. I believe the difference between rm and rmdir exists because of differences in the way the C library treats each. At any rate, the first should work, while the … Read more
It’s not possible in 3.0. It was only possible on 2.0 because it was an exploitable bug. The bug was fixed in 3.0 which is why it’s not possible. Apple don’t intend the Default.png to be a “splash screen”. If you read the HIG, you’ll see that the Default.png is suppose to represent your user … Read more
Check that Apache has execute rights for /root, /root/site and /root/site/about. Run: chmod o+x /root /root/site /root/site/about You can find a more secure way in Elijah’s answer.
Symbolic links have more functionality, while junctions almost seem to be a legacy feature because of their limitations, but the security implications of these limitations are specifically why a junction might be preferred over a symbolic link. Remote targeting makes symbolic links more functional, but also raises their security profile, while junctions are safer because … Read more
readlink -f “$path” Editor’s note: The above works with GNU readlink and FreeBSD/PC-BSD/OpenBSD readlink, but not on OS X as of 10.11. GNU readlink offers additional, related options, such as -m for resolving a symlink whether or not the ultimate target exists. Note since GNU coreutils 8.15 (2012-01-06), there is a realpath program available that … Read more
In short, define the following environment variable: CYGWIN=winsymlinks:nativestrict According to Cygwin documentation: If set to winsymlinks:native or winsymlinks:nativestrict, Cygwin creates symlinks as native Windows symlinks on filesystems and OS versions supporting them. The difference between winsymlinks:native and winsymlinks:nativestrict is this: If the filesystem supports native symlinks and Cygwin fails to create a native symlink for … Read more
Why can’t I symlink into /usr/bin? El Capitan’s new System Integrity Protection feature prevents changes to several core parts of OS X, including most of /usr/, even by root. How can I still add executable files to my path? Local customizations, such as what you’re doing, belong in /usr/local instead. The path /usr/local/bin doesn’t exist … Read more
Yes, you can! In lieu of a symlink (which won’t work on Windows), create a stub document that has nothing in it but a .. include:: directive. I ran into this trying to link to a README file that was in the top of the source tree. I put the following in a file called … Read more
