Open and edit files from remote server
In my workplace, every developer needs to work on own directory in a shared dev server.
Here is the command I ran to open my directory and edit my files remotely.
1 | sshfs username@192.168.0.6:/remote/directory/path /mount/to/your/local/directory/path |
* 192.168.0.6 is IP of remote server.
After you ran this, access to /mount/to/your/local/directory/path directory is same as access to remote directory.
Have fun.
