To open a file in Vim and go to a specific function or line number, you can use the :function or :line commands, respectively.
For example, to open the file file.txt and go to the function main in Vim, you can use the following command:
vim +/main file.txt
This will open the file file.txt in Vim and jump to the first occurrence of the string main.
To open the file file.txt and go to line number 50 in Vim, you can use the following command:
vim +50 file.txt
This will open the file file.txt in Vim and jump to line number 50.
Keep in mind that the + symbol is used to specify a command to be executed when the file is opened. You can also use the -c option to specify a command to be executed, as in:
vim -c "50" file.txt
This will open the file file.txt in Vim and jump to line number 50.
