In Vim, you can open a file and go to a specific function or line number by using the following command:
vim +[line number] [file name]
For example, if you want to open a file named “example.txt” and go to line number 50, the command would be:
vim +50 example.txt
If you want to go to a specific function, you can use the following command:
vim +/[function name] [file name]
For example, if you want to open a file named “example.txt” and go to the function named “main”, the command would be:
vim +/main example.txt
Once you are in Vim, you can navigate the file and make changes as needed.
