I have a directory in Linux machine have sub directory's. need to identify sub directory and also need to identify is that directory is a symlink.
Below code not working for me
File.directory?( "/usr/java/default/" )
File.symlink?( "/usr/java/default/" )
Use the File:ftype() method. See
https://ruby-doc.org/core-2.7.1/File.html#method-c-ftype for details.

I'd like to rename a directory with the Storage Facade (S3 object). I've tried using move and rename, both with and without trailing slash, none of these work.
Storage::disk('s3')->move($dir_temp, $dir_final);
Storage::disk('s3')->move($dir_temp.'/', $dir_final.'/');
Storage::disk('s3')->rename($dir_temp, $dir_final);
Storage::disk('s3')->rename($dir_temp.'/', $dir_final.'/');
I did use rename function, and it did work for renaming a directory.
This code worked for renaming directory dir 1 to dir 2:
Storage::disk('movies')->rename('dir 1', 'dir 2');
Now, it depends on what error did you get.
make sure, you have rwx rights to the parent directory
make sure the source directory exists, and the destination does not
make sure the name is valid for a name, for example, windows OS will not allow certain characters in the name
make sure you do have permissions to the source directory for that operation
be very carefull with slashes, as windows OS has different path slashes than linux.
For the directory separator, to be platform independent, you can use
$DS = DIRECTORY_SEPARATOR;
Also, the permissions can be quite tricky, as, if you have the app deployed, traditionally, the http user is the user under which all the code is executed, so keep that in mind.
I wrote a program in python that created folders. I'm having difficulty removing some of the folders due to this glitch.
I already figured out how to prevent it. But for the folders already created are irremovable. I get this error message when trying to delete them.
Could not find this item. This is no longer located at ... Verify the items location and try again [Try Again][Cancel]
I tried removing the folders by typing dir /x into a console
and then using the shorthand of the folder name with the del program. ex: del FOLDER~1
But that only works some of the time.
The only difference between the broken and non broken folders is the space at the end of the folder name when creating.
How to make a broken directory:
mkdir "broken folder /"
How to make a normal directory
mkdir "normal folder/"
Extra info:
The folders can still be used. The files inside can be deleted. Just not the folder itself or its parent folder.
When this glitch occurs in python using os.mkdir it also creates two directories with the exact same name. Only one can be deleted regularly.
I wrote a python script that fixes all the broken folders. So if anyone hits this issue. Hope this helps. Just drop into whatever folder is full of broken folders. Its kind of poorly made. But gives an idea about what you need to do.
from glob2 import glob
import os
import shutil
#find all folders
folders = glob("./**/")
# for each folder check if they exist and rename them to have an A at the end of their name.
for fold in folders:
if fold != ".\\":
if os.path.exists(fold):
name = fold.rsplit("\\", 2)[-2] + "A"
print(name)
print(fold)
os.rename(fold, name)
Currently I am using following function to get the temporary folder path for current user:
string tempPath = System.IO.Path.GetTempPath();
On some machines it gives me temp folder path of current user like:
C:\Documents and Settings\administrator\Local Settings\Temp\
On some machines it gives me system temp folder path like:
C:\Windows\TEMP
MSDN Documentation also says that above API returns current system's temporary folder.
Is there any other API available which gives me current user's temporary folder path like this:
C:\Documents and Settings\administrator\Local Settings\Temp\
System.IO.Path.GetTempPath() is just a wrapper for a native call to GetTempPath(..) in Kernel32.
Have a look at http://msdn.microsoft.com/en-us/library/aa364992(VS.85).aspx
Copied from that page:
The GetTempPath function checks for the existence of environment variables in the following order and uses the first path found:
The path specified by the TMP environment variable.
The path specified by the TEMP environment variable.
The path specified by the USERPROFILE environment variable.
The Windows directory.
It's not entirely clear to me whether "The Windows directory" means the temp directory under windows or the windows directory itself. Dumping temp files in the windows directory itself sounds like an undesirable case, but who knows.
So combining that page with your post I would guess that either one of the TMP, TEMP or USERPROFILE variables for your Administrator user points to the windows path, or else they're not set and it's taking a fallback to the windows temp path.
DO NOT use this:
System.Environment.GetEnvironmentVariable("TEMP")
Environment variables can be overridden, so the TEMP variable is not necessarily the directory.
The correct way is to use System.IO.Path.GetTempPath() as in the accepted answer.
I have this same requirement - we want to put logs in a specific root directory that should exist within the environment.
public static readonly string DefaultLogFilePath = Environment.GetFolderPath(Environment.SpecialFolder.UserProfile);
If I want to combine this with a sub-directory, I should be able to use Path.Combine( ... ).
The GetFolderPath method has an overload for special folder options which allows you to control whether the specified path be created or simply verified.
I'm working with a directory that's an alias on Mac OS, with Ruby. This is a folder that points to another folder. How can I determine the original directory that this alias points to?
In one of my Jenkins jobs, there is an alias called lastStable, which points to the latest stable build folder:
path = /Users/steve/.Jenkins/jobs/MyApp/lastStable
lastStable actually points to a folder called 2013-08-06_10_50_49.
How can I get this info dynamically in Ruby?
File.realpath resolves symlinks.
You could do:
File.realpath '/usr/bin/ruby'
#=> "/usr/bin/ruby1.9.3"
You can use the readlink method:
File.readlink(path)
