Configuration file

The only required option to start sending messages to mattermost is the webhook url. You can either set this in a configurations file (globally in /etc/mattersend.conf or locally in $HOME/.mattersend.conf) or specify it on the CLI with the --url argument.

You can have multiple sections to override DEFAULT settings and later select them from the CLI with the --section argument.

This is an example of a configuration file for mattersend:

url =
icon = :ghost:
username = This is a bot
channel = @myself

icon = :angry:
username = AngryBot

Example usage

echo "Hello world!" | mattersend -U

# you can omit -U with mattersend.conf
echo "Hello world!" | mattersend

# send file content
mattersend -f todo.txt

# table data
echo -e "ABC;DEF;GHI\nfoo;bar;baz" | mattersend -t
