hi @andkirby
I want to ask, why can I sent from grep command?
my sh script like this :
#!/bin/bash
message=$(grep AUDIT audit.txt)
slack ${message}
if I execute this, I always get this error:
/home/ubuntu# ./test_sent.sh
Sending to ...
invalid_payload
can you solve this?
Hi @farisalfa,
The only one who can solve it that's you. ;)
I guess, that's not about script but about Bash scripting knowledge.
Just double checked — it works fine. Think about double quotes for your variable.
Thanks bro', u saved my night 👊🏻
Just an insight to those facing issues with /usr/bin/slack due to permission accessing to /usr/bin, you can move the script under usr/local/bin/slack.
So that the two commands to run will be:
curl -s https://gist.githubusercontent.com/andkirby/67a774513215d7ba06384186dd441d9e/raw --output /usr/local/bin/slack
chmod +x /usr/local/bin/slack
hope it helps 👍
great script @andkirby 💪
Hi,
when sending a message in this way:
slack.sh ":arrow_right: data seeding"
emoji appears as text and it is not rendered, what am I doing wrong ?
Thanks!

@jmhostalet, I assume, they added mrkdwn type for that.

great script @andkirby 💪
@d4r1091, it's a pleasure to know it. ;)
@jmhostalet, just double check it. It works with emoji. According to off-docs mrkdwn=true always.

@Lalit-1219, it's not about this script definitely. ;)
You may try to adjust nofication settings. I remember there is "keywords" feature.
