PipeCheck (pc)

Pipecheck is a tool to help debug / test pipe'd commands on your terminal:

$ echo "foo\nbar\nbaz" | pc | xargs -n 1 echo -
==================================================================
 PipeCheck: The following was read in and will be passed through:
==================================================================
foo
bar
baz
===============================
 Proceed with this data (y/N):y
===============================
- foo
- bar
- baz

Note: When an n or any other key is provided, the command will terminate and send an empty buffer to the subsequent commands. IE the string of pipes do not terminate, but continue one with an empty buffer.

How to install

Currently the only way to install:

go install github.com/goodmustache/pc@latest

What's the difference between this and tee /dev/stderr?

Honestly? Not much - you get a pause to validate if you want things to continue. I don't know how much this helps others, but I found it useful.
