A command-line utility in Go that reads from standard input and replaces specified substrings with their corresponding replacements based on a config file.
The mask utility scans text from standard input and looks for substrings defined in a configuration file, replacing them with the specified replacements. It's not limited to whole words but replaces any matching substrings.
The substring matches and replacements are all lower-cased by default.
The default configuration file is located at ~/.mask.config and contains the substrings to be masked, along with their replacements. Each line has the format substring:replacement.
go install github.com/skepticfx/mask@latest
~/.mask.config
hello:bye
ice:fire
Running mask for the first time creates a sample config file under ~/.mask.config
- Ensure that you have a configuration file at
~/.mask.config. - Run the
