When I have to connect to my server on VPS or AWS EC2, I forgot some command I have to googling every time, then I decided to notes it and put it to ONE place. That’s why I wrote this post.

SFTP Command

Connect with SFTP

sftp -i /path/to/pem-file user@ip-address
# with option port=xxx
sftp -i /path/to/pem-file -o "port=xxxx" user@ip-address

Download a file/folder from server

# download a file from server
get myfile.txt
# download a folder
get -r myawesomeFolder

Upload a file/folder to server

# upload a file
put myfile.txt
# upload folder
put -r myFolder

Change / list directory

# display local directory (aka ls for local)
lls
# change directory for local machine
lcd
# display directory (on server)
ls
# change directory for server machine
cd

File System

Display free disk space with

df -h

Display total size of directory

du -hs /path/to/directory
# total size of current directory
du -hs .

Find largest directories (10 items)

du -hs * | sort -rh | head -10

Happy Coding ❤️
