Example:
sh
printf "%s\n%s\n%s\n" alpha bravo charlie > example.txt
cat example.txt | checkline
You should see each line with a checkbox and text:
txt
[ ] alpha
[ ] bravo
[ ] charlie
Move up and down in the list by typing arrow keys.
Check or uncheck any checkbox by typing space or return.
Check each line that you want, then type ESC to escape.
The command prints each line you want.
The purpose of this command is a simple picker, that is easy to use, and that work wells in on the command line such as within a pipe.
The purpose isn't intended to handle very long lines, or very long inputs.
See the command vipe that can pipe in and out of $EDITOR:
