Here I’m mentioning all the commands related to Vi and Vim editor that I learn

Command to delete all lines in Vi Editor:

:1,$d 

Delete a single line where the cursor is

dd

Find and /replace

To search a word that has the character forward slash / or any special characters then simply include backward slash \ before that \/

:%s/find\/words\~/replacewords/g

Add Text to beginning of every line – use ˆ
Add Text to end of every line- use $

:g/^$/d

Remove Blank Lines that contains space

Objective: Upload Files/Folder from my local to server. (How to Send Files from your localhost to Another Server through SSH)

Challenge: I’m bored to use Filezilla. So just have to use putty or Git Bash or Windows Subsystem.

I have used Ubuntu Subsystem in my Windows 10 for SSH access.

Solution: Use Secure Copy Command from your local machine and login to server directly.

Command:

sudo scp -i key.pem -r /mnt/d/sourcefolder/ [email protected]:/var/html/destination/

1. Sudo – So to not ask permission for each and every file.
2. scp – Secure Copy command to copy files between servers. you should use scp so it would use SSH for transferring files and would use authentication like password or pem key.
3. -i key.pem – this is the key for my server login authentication.
4. -r -recursive files/subfolders inside the folder.
5. /mnt/d/sourcefolder/ – Source folder in local.
6. [email protected]: – user in the particular server and its IPv4. you can also use root or ubuntu.
7. /var/html/destination – Destination folder

Task Completed Successfully.

Note: Remember that the folder copied to the server is under the user centos/root/ubuntu.
