Another method is to delete all the empty lines in the file and comment lines starting with # cat squid. conf. default | grep-v '^ $' | grep-v '^ #' 2) after opening a file and editing it, the logged-on user has no write permission for the file, you cannot save the vi file: w/tmp/1. since you cannot save the disk, you do not want to give up all the modifications you have made, First temporarily save to/tmp/1: 20, 59 w/tmp/1 or simply save the content between 20th and 59 rows into a file/tmp/1 3) use VI to edit a file, however, you need to delete the contents of a large segment. vi file Ctrl + G move the cursor to the row to be deleted, press ctrl + G to display the row number, and then press Ctrl + G at the end.: 23,104 5d if the two row numbers are 23 and 1045, you can delete all the contents of the two rows. you can also use ma in the start and end lines, mark the mb command and use: 'A, 'bd delete. 4) add a string vi file at the beginning or end of the line to the entire file or several lines: 3, $ s/^/some string/insert some string before the beginning of the first line to the last line of the file: % s/$/some string/g add some string: % s/string1/string2/g at the end of each row of the entire file replace string1 with string2 in the entire file: 3, 7 s/string1/ String2/replace string1 in the third to seventh rows of the file into string2Note: s is substitute, % represents all rows, g represents global5) edit two files at the same time, copy and paste the text vi file1 file2 yy in two files, open two files at the same time, copy the row where the cursor of file 1 is located: n switch to file 2 (n = next) p paste the copied line at the cursor position of file 2: N switch back to file 1 6) replace the path in the file: % s #/usr/bin # g replace all the paths/usr/bin in the file with/bin or use: % s // usr/bin // bin/g indicates '/' is a single character '/' 7 with a symbol before) if you want to annotate a multi-line program with a multi-line comment with vi, a stupid way is to insert #, and then use j to jump to the next line. command.
