Linux command line 指令

1. 縮短command line 裡面的路徑(terminal instance)
   
   本來的路徑長相
   usr@ubunt:~/Downloads/Cython/Delta_person_detection/faster-rcnn$
   
   執行  PS1='\u@\h:\W\$ '
   
   會變成
   usr@ubuntu:faster-rcnn$
   
   

   To change it "permanently" (永遠改成這種形式)

   In your ~/.bashrc, find the following section:

   if [ "$color_prompt" = yes ]; then
       PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\W\[\033[00m\]\$ '
   else
       PS1='${debian_chroot:+($debian_chroot)}\u@\h:\W\$ '
   fi

2. vi 裡面要刪除整行的指令：dd
   

3. 用檔名找檔案 find . -name "*prototxt" -print
