Notes about using the vim editor, especially useful regular expressions (regex, regexes).

Run an external command on all matching lines

:g/pattern/.!command

It's important that the dot command (.) appear between the search pattern and the bang (!) beginning the external command.

If ntpdate is installed:

sudo ntpdate pool.ntp.org

To install ntpdate:

sudo apt-get install ntpdate # for Ubuntu-like

There are times notifications aren't wanted about either a changed repo file or a new file that needs to be added to the repo. However, adding the name of the file to .gitignore might not be a good option, either. For example, locally-generated files that other users aren't likely to generate (e.g., files created by an editor) or files of experimental test code might not be appropriate to appear in a .gitignore file.

In those cases, use one of these solutions:

If the file is a changed repo file

Use the command:

git update-index --assume-unchanged "$FILE"

	do shell script ¬
	(POSIX path of ((path to me as text) & "::")) ¬
	& "toggleHiddenFiles.sh"
