Filename saves the content from line n1 to line n2 to the existing filename File: wq to save the file, exit vi: x to save the file, exit vi: ZZ to save the file, and exit vi: q: Do not save the file and exit vi (if the file has changed, you cannot exit): q! Do not save the file, exit vi: ZQ do not save the file, exit vi4. in command mode, you can enter the following command: (1) Move the cursor command h: Left l: right k: Top j: bottom left cursor key right cursor key up cursor key down cursor key (2) insert command I: insert content at cursor I: insert content in the first line: insert content A after the cursor: insert content o at the end of the current row: insert A new row O below the current row: insert A new row above the current row (3) delete command x: delete character X at the cursor: Delete a character d0 before the cursor: Delete a string of characters D from the first character of the row where the current cursor is located to the first character of the current cursor: delete a string of characters dd from the character where the current cursor is located to the last character in the row where the current cursor is located: delete all characters dw in the row where the cursor is located: delete a word starting from the character at the cursor, for example, a boy girl pig. if the cursor is at l, after dw, the result is: if the cursor of a boy girpig is at the space between l and p, after dw, the result is: a boy girlpig if the cursor is at B, after dw, the result is: a girl p Ig # dd: delete the #-1 line from the row where the cursor is located to the end (# must be replaced by a number) # x: delete # Characters starting from the character where the cursor is located (# must be replaced by digits): n1, n2 d: delete content from line n1 to line n2 (4) copy command: n1, n2 t n3: copy the content from line n1 to line n2 to the next line (5) of line n3 with the following command: n1, n2 m n3: move the content from line n1 to line n2 to the next line (6) in line n3 modify/replace command r: enter a character to replace a character at the cursor R: replace from the character at the cursor, followed by one character overwritten by the input character s: enter a string of characters to replace the character S at the cursor: first clear the row where the cursor is located, you can enter a string of characters in the current line cc: first clear the row where the cursor is located, you can enter a string of characters in the current line cw: modify a word for example: the AB cdef ghijk cursor is at d. After cw is input, the result is AB cde $ ghijk. if pqghd is input, the result is: AB cpqghd ghijk if you enter p and press ESC, the result is: AB c P ghijkC: modify the part starting from the cursor and following the line. for example, the AB cdef ghijk cursor is at d. after entering cw, the result is: AB cdef ghij $. after entering pqghd, result: AB cpqghd (7) cursor position command 0: Locate the beginning of the row where the cursor is located $: locate the end of the row where the cursor is located :#: locate Row # First row: $: locate Row/exp: locate string exp? Exp: move forward to the string exp/^ exp: Locate the row whose first line is the string exp/exp $: Locate the row whose last line is the string exp n, m? /Exp: Search for the string exp from n rows to m rows (this command is to be discussed) n, m |/exp: Search for the string exp from n rows to m rows (this command is to be discussed) (8) search replacement command: s/exp1/exp2/g: replace the current line string exp1 with the string exp2: n, m s/exp1/exp2/g: replace the string exp1 from row n to row m with the string exp2: g/exp1/exp2/g: replace the string exp1 of the current row with the string exp2: g/exp1/s // exp2/g: replace the string exp1 in the full text with the string exp2 (9) undo command u (10) buffer command by default, vi uses the unknown buffer, for example, although some parts of the file are deleted, they can still be revoked using the u name. Yy: place the row where the cursor is located in the unknown buffer zone Y: place the row where the cursor is located in the unknown buffer zone p: paste the content in the buffer zone to the next row of the cursor P: paste the content in the buffer to the previous line of the row where the cursor is located "# yy: put the row where the cursor is located into the buffer # (# a ~ is required ~ Z instead) "# p: paste the content in buffer # to the next line of the row where the cursor is located (# a ~ is required ~ Z instead) "# P: paste the content in the buffer # to the top row of the cursor (# a ~ is required ~ Z instead) "# d: delete the current row and put the content of the current row into the buffer # (11) other command: set nu: Display row number: set nonu: cancel row number: n locate to the next file: N locate to the previous file vi 1.c 2.c 3.c: open 3 files at a time first open 1.c, enter: n command, open 2.c, and then enter: after the n command is run, 3.cwill be opened, and after the: N command is input, 2.cwill be opened, and after the: N command is input, 1.cwill be opened.
