# `watch`

## Watch Differences

- `watch -d stat "$file"`
- `watch -d ip a`

## With Makefiles

```sh
watch --chgexit ping -c 1 dmz.rs && sleep 3 && unison -batch pir
```

## Check Progress

```sh
watch 'ls **/*.pdf | column'
```

---

# Watch Shell Scripts


```sh
watch -e ./script.sh
```

---

# Slow Down

```sh
function slow(){
	ff=/tmp/bashpipe_$(date +%s)
	mkfifo $ff 2>/dev/null
	( cat $ff | perl -We 'use Time::HiRes;$|++;while(read(STDIN,$c,1)){Time::HiRes::usleep(15000);print $c;}' )& exec &> $ff
}

```

## Safety?

- no

## `htop`?

- no

## `speedtest`?

- **YES**
