Open a file with su/sudo inside Emacs

由 喜你入骨 提交于 2019-11-27 08:57:09
问题 Suppose I want to open a file in an existing Emacs session using su or sudo , without dropping down to a shell and doing sudoedit or sudo emacs . One way to do this is C-x C-f /sudo::/path/to/file but this requires an expensive round-trip through SSH. Is there a more direct way? [EDIT] @JBB is right. I want to be able to invoke su / sudo to save as well as open. It would be OK (but not ideal) to re-authorize when saving. What I'm looking for is variations of find-file and save-buffer that can

How can I copy permissions from a file that already exists?

由 人走茶凉 提交于 2019-11-27 08:20:37
问题 I have to write a program in C (on a Unix-like system) and this is my problem: I have a file (FILE1) and I want to create another file (FILE2) which has the same permissions of FILE1. Then I have to create another file (FILE3) which has the same permissions of FILE1 but only for the owner. I would use chmod() to change permissions but I don't understand how to obtain the permissions of FILE1.

Howto avoid the “EACCES permission denied” ON SDCARD with KITKAT 4.4.2 Version. New policy from google

With the android kitkat 4.4.2 version is a new google policy implemented for writeaccess, which I do not understand so far. I read a lot about this issue with other apps. They get a "EACCES permission denied". My app needs to write/unzip a zipfile, also write to a sqlite-database. How can this EACCES permission denied issue be solved with Android version 4.4.2 KITKAT ? WiFi I found a working solution to this issue in xda forum ; there is no need for rooting. Here's an example : /** * Returns an OutputStream to write to the file. The file will be truncated immediately. */ public OutputStream

java set file permissions to 777 while creating a file object [duplicate]

Possible Duplicate: How can I set the umask from within java? How do you set file permissions to 777(or any other arbitrary permission) while creating a file object in java? If you set the umask(2) to 0 before starting the JVM, all files and directories created will be created with full permissions for everyone. This is probably a bad idea. You can use the File.setReadable() , File.setWritable APIs to fiddle with the mode bits after the file has been created. That's often good enough, if you're granting permissions; if you're trying to remove permissions from other users, then your permissions

问题 I am trying to save some data from my app in a simple text file on the internal private storage area (app user preferences).

I have also tried to create the file using the methods available in
