I want to find all places with skip_all_flag when I do initial check via cargo check:
cargo check | rg skip_all_flag
^^^this doesn't work. Why?
Compiler errors from cargo run/cargo build/cargo check go into stderr, not stdout; whereas | only pipes stdout. Searching for how to pipe stderr instead gives possible solutions, e.g. the following is fairly concise:
cargo check 2> >(rg skip_all_flag)
though I don’t understand all the implications of this bash syntax, and some commenter remarked something about it and “stdlog pipe”… IDK. So the more sane approach might be
cargo check 2>&1 >/dev/null | rg skip_all_flag
