Instead of constantly checking a long running command you can get notified when it finishes.
Here's an example that sends a notification to slack:
sleep 10 && echo "hello world" | notify slack --token='xxxx-xxxxxxxxx-xxxx' --channel='#notifications'
hello worldYou can download and install the latest version of notify from GitHub releases.
You can also install a pre-compiled notify from gobinaries or from the latest source if you have go installed:
# Using gobinaries
curl -sf https://gobinaries.com/montanaflynn/notify-cli/cmd/notify | sh
# From source
go get github.com/montanaflynn/notify-cli/cmd/notifyOnce installed add | notify to the end of a command. By default it makes a bell sound when the command finishes but can be configured to send a slack message or a webhook instead. Here's the usage from notify --help:
