peek(1) is a utility that reads standard input and writes to given outputs without echoing to the terminal. It has a number of features that make safer usage convenient and both the code and the man page are very cleanly written. This tool's utility is obvious in the examples; while shell scripts shouldn't accept secrets, if they were to do so this is a thoughtfully designed utility for that task.

This is imported from my source tree with slight tweaks for this repository. @silt helped review this code when it was first written (four months ago).

mm(1) isn't suited for this task because it doesn't prevent terminal echoing. The shell built-in read doesn't either. The featureset of this utility wouldn't make sense for any other one, either (-1 could be | head -n 1, -e could be | tee /dev/stderr, -n could be | tr -d \\n, -o is a default everywhere, -p is a pipe, and -t doesn't make sense elsewhere).

Yes, actually. After rethinking it I rewrote the utility to be as simple as possible (and have -t be the default as it should have been). The man page has been updated to match, including incorporating all of your comments which I found to be useful.

This appears to imply that there exists a multitude of other possible sources, but it's not made clear what those are or how to make use of them. Does it support reading input from… files? TCP sockets? IRC messages??

trinity commented

The "i.e." stands for "id est" and can be read as "in other words". Perhaps I should use the English. I mean to say that the source other than a terminal, in this case, is a pipe.

It's about the fundamentals.

This feature will be available in whatever shell the user wants.
Keeping this functionality in a separate program will make it easier to debug it separately.
No functionality is lost by making this a separate program.

A program should do one thing well. peek(1) does one thing well. Mixing its functionality into another program is unnecessary, makes it generally less valuable, and makes the other program more complex.

I can't find a way to rewrite this in Rust without vendoring a crate or writing termios C bindings.

I didn't know about stty(1p) when I wrote this utility but I think for this purpose peek(1) does a better job.

I requested (in private messages) silt's review because a number of changes were required last-minute to make testing work (peek -i </dev/null >/dev/null would fail).

Merged (via cherry-picking to avoid redundant commits).
