This only list some frequently asked questions when you start using command line.

Windows use \ as directory separator, while Linux use /

Example

Windows

partition + :\ + folder + \ + filename

C:\Program Files\Adobe\Photoshop CC\amtlib.dll
D:\学习\abs-132.rmvb

Linux

Folder + / + filename. Linux DOES NOT have partition in path. NO C,D etc.

/home/at15/Downloads/abs-132.rmvb
/etc/nginx/conf.d/tongqu.lk.conf
