A command line utility for sending periodic email with the output of long running commands.
Dual-licensed under MIT or the UNLICENSE.
Currently, you have to build with Cargo, Rust's package manager. I'll hopefully release binaries soon.
git clone git://github.com/BurntSushi/rust-cmail
cd rust-cmail
cargo build --release
./target/release/cmail --help
```
Usage: cmail [options] [
Options: -h, --help Display this help message. -p ARG, --period ARG Data is emailed at this period in seconds. Set to 0 to disable and send only one email when the command completes. [default: 900] -s, --silent Don't pass the command's stdout/stderr to the terminal. Instead, only send stdout/stderr in email. -a, --send-all Send the entire command's output on each email. N.B. This saves all output in memory. -t ARG, --to ARG The email address to send to. By default, this is set to $EMAIL. If neither $EMAIL nor --to are set, then an error is returned. ```
cmail responds gracefully to signals or if the command being run is
terminated unexpectedly. Internally, cmail uses sendmail to send email.
Send whatever is on stdin:
bash
cmail <<EOF
This is going to
my email
EOF
Report all 80 column violations in Lua files. Don't show output in terminal:
bash
find ./ -name '*.lua' -print0 | xargs -0 colcheck | cmail -s
Run a du command on a huge directory, and send an incremental email update
every 10 seconds (the default is 15 minutes):
bash
cmail -p 10 du -csh *
This is ported from an earlier version I wrote in Go: https://github.com/BurntSushi/rust-cmail
Since this is my second run at writing this, it's a little clean this time around. All in all, I'm quite fond of the structure of both programs (well, the structure is quite similar!).
