# rl
Rate limit messages from stdin. (keep or drop those exceeding the limit)
# Use case
* When sending data to mattermost (or slack), it's convenient to limit the amount of data that can be sent.
E.g. when using [mattertee](https://github.com/42wim/matterstuff/tree/master/mattertee) to send output to mattermost, you can now just pipe it through rl so that your channels aren't being flooded.
* Tailing -f a very quickly increasing logfile when in tmux remotely ;)
# Installing
## Binaries
Binaries can be found [here] (https://github.com/42wim/rl/releases/)
## Building
Go 1.12+ is required.
```
go get github.com/42wim/rl
```
You should now have rl binary in the ~/go/bin directory:
```
$ ls ~/go/bin/
rl
```
# Usage
```
Usage of ./rl:
-f string
define a file as input
-k keep the messages instead of dropping them
-r int
limit to r messages per second (drops those exceeding the limit) (default 5)
```
(the number of dropped messages will be sent to stderr, when not using the -k switch)
# Example
```
journalctl -f | rl -k -r 5
```
