When the file contains the tab key, you cannot see it. To display it:
: Set list
Now the tab key is displayed as ^ I, and $ is displayed at the end of each line, so that you can find the spaces that may be ignored.
Change:
Use the 'listchars' option:
: Set listchars = tab:>-, trail :-
Now, the tab is displayed as ">-", and the extra blank characters at the end of the line are displayed "-".

: S/^ [^ I] \ + // remove the blank characters at the beginning of the line
Use. to indicate the current row.

20. Call the shell command in VIM
:! Command
Do not exit vim and run the shell command to display the command output in the vim command area, without changing the content of the currently edited file.
Example:
1): R! Command
Insert the shell command result to the next line of the current line.
: R! Date
Reads the system time and inserts it into the next row of the current row.
2) start line number, end line number! Command
Enter the content in the range specified by the starting line number and ending line number to shell command for processing, and replace the content in the range specified by the starting line number and ending line number with the processing result.
Example: 62,72! Sort: sorts the content from 62 rows to 72 rows.
: 62! Tr [A-Z] [A-Z], converts 62 rows of lowercase letters into uppercase letters
3): start line number, end line number W! Command
Use the content in the range specified by the start and end line numbers as the command input. Does not change the content of the currently edited File
Example: W! Sort sorts the content from 62 rows to 72 rows, but the sorting result is not directly output to the file being edited, but is displayed in the area where Vim knocks the command.
