ftags (File Tags) is a simple command line file tagging utility that helps to organize your files by assigning tags to them.

Assuming that you already have Node.js and Npm installed: npm i -g ftags

ftags stores it's data in a single database file (.ftags.db). By default ftags searches for this file in the currect working directory. If it won't be able to locate it there it will try to find it in all the parent directories up to the root of the file system. If the file won't be found after that it will be assumed that the global database file should be used. Global database default location is the home directory of the user.

If you wan't to create a new .ftags.db file in the current directory and those scope it out from the global database just use the --init option in the command:

ftags --init

ftags example.txt tag1 tag2 'multiple words tag'

ftags tag1 tag2

ftags tag1 tag2 --exec=open

This command will run the specified program and pass found files as arguments e.g.:

open file1 file2 file3
