How to Use Vim to find and replace

In VI/vim, you can use the: s command to replace the string. This command has many usage methods for different details, which can implement complex functions and record several types here for future query convenience.

• Replacement: S/pattern/replacement/
• Replacement: S/pattern/replacement/g
• Replacement: N, $ S/pattern/replacement/
• Replacement: N, $ S/pattern/replacement/g

Note:N is a number. If n is., it indicates starting from the current row to the last row.

• replacement : % S/pattern/replacement/ (equivalent to : g/pattern/S // replacement/)
• replacement : % S/pattern/replacement/g (equivalent to: G/pattern/S // replacement/g)
  note you can use # As the separator. In this case, the/in the middle is not used as the separator.
  
• replacement/: s # pattern/# replacement/#
