Here are some cool Vim command line tricks:
1. Open at the end of a file
vi + file.txt
The plus sign added before the file name opens up the file with the cursor at the end of the file. This can be handy if you have a huge text file you and you don’t want to scroll down.
2. Open file at specific line
vi +n file.txt
If you add a number (replace n with a number in case you hadn’t guessed) the cursor will go exactly to that line number. Extremely handy for large text files or error messages that specify a line number in a config or source file.
3. Open file at a pattern
vi +/pattern file.txt
This will open the file on the same line as the pattern you specify (first instance of it). This is great if you have a specific phrase to search for.
4. Recover a file after a crash
vi -r file.txt
Use -r to open a file and recover it after a crash. This could save your butt someday.
5. Run a script against a file
vi -s file.txt < script.sh
This trick could be super powerful, but also dangerous. This allows you to run a script against the file while opening, usually a search or something of that sort.
I hope this helps, I’m going to post more stuff as I learn it, there’s a reason they’ve written whole books about Vim, it has a ton of features. If people enjoy these tips, I’ll add some more later.
