Info

Vim also has a handy shortcut for opening man pages for the word under the cursor. Just hit K and aman page will show up for that specific word (if there is one, that is):Finding text in Vim is as easy as hitting /. Just type / + the text to find, and hit Enter to start searching.Vim will go to the first occurrence of that text. Hit n for next occurrence, N for previous occurrence.Our favorite editor has a powerful find and replace feature, similar to the sed command. Let's say wewant to replace all occurrences of the string CWD with the string DIR. For this, just type:
:1,$s/CWD/DIR/g:1,$ - start from line one, till the end of the files - substitute/CWD/DIR/ - replace CWD with DIRg - global, replace all occurrences.Let's do another common example that often comes up in programming: commenting lines of code.Let's say that we want to comment out lines 10 to 20 in a shell script. To do this, type::10,20s/^/#\ /g
