candrholdings / slack-cli

A command line interface for Slack implemented using node.

slack-cli

A very simple command line interface (CLI) for Slack.

Send a message

slackcli -t slack_token -g group_name -m "Hello World!"

Or if the environment variable SLACK_TOKEN is set, you can simply use,

slackcli -g group_name -m "Hello World!"

Or use -h instead, if you want to post to a channel

slackcli -h channel_name -m "Hello World!"

Send a file

slackcli -t slack_token -g group_name -f filename -m "Download this file"

Send from standard input

# slackcli -t slack_token -g group_name -c
Hello World!

Send with customized icon

# slackcli -t slack_token -g group_name -u goat -e :goat: -m baaaaaaaaa

Install

With npm do:

npm install -g slack-cli

Usage

# slackcli --help
USAGE: node <SOMEWHERE>\npm\node_modules\slack-cli\bin\cmd.js [OPTION1] [OPTION2]... arg1 arg2...
The following options are supported:

  -u, --username <ARG1>         Specify the name of the bot.
  -i, --icon_url <ARG1>         Specify the URL to an image to use as the icon for this message.
  -e, --icon_emoji <ARG1>       Specify the emoji to use as the icon for this message.  This cannot be used together with icon_url.
  -m, --message <ARG1>          Specify the text of the message to send.
  -g, --group <ARG1>            Specify the group name.
  -h, --channel <ARG1>          Specify the channel name.
  -f, --file <ARG1>             Specify the name of the file to send.
  -t, --token <ARG1>            Specify the Slack API token.
  -v, --verbose                 Set to verbose mode.
  -c, --console                 Use console to input message.
  -w, --waitForText <ARG1>      Specify the text message to wait.  Default timeout is 30 seconds.
  -s, --timeout <ARG1>          Specify the seconds to timeout when using --waitForText.
  -l, --linkNames               Link names in messages.
  -r, --read                    Read to stdout.
  -a, --asUser                  Post message as a user for which API Token belongs to.
  -p, --pin                     Pin message after sending.

Advanced Mode

To reuse the Slack token, you can set the token as the environment variable SLACK_TOKEN like this.

SET SLACK_TOKEN=xoxo-12345678-12345678-12345678-123abc

slack-cli's Issues

mutliline messages don't work

Hi and thank you for a very useful project!

To send multiline messages you need the \n to break the line.
See: https://api.slack.com/docs/message-formatting#multiline_messages

The problem is that the message that is actually sent to Slack escapes it and makes it: \\n.

Thank you in advance.

Error while trying to send a message to a channel

I'm getting the error shown below while trying to use the command:
slackcli -t token -h channel-name -u username -m "message"

cmd.js line 219 cannot call forEach on undefined while using -h channel

Post files and message as_user

Apparently it is now possible to post as actual user rather than a bot:

Please add the option. Thanks!

How to use it with webhook ?

How to use it with webhooks ?

Feature Request: Set your current status

It would be awesome if we could use this CLI to set our current status, and how long it should last before being automatically cleared. I'm not certain if that's possible or not, but it would be a great addition to the feature set. Thanks!

Download files

Would it be possible to download files given the recent Slack API changes?

https://medium.com/slack-developer-blog/important-changes-to-files-in-the-web-api-eb38f2a9c1e7#.npbnybs0t

Looks like most Slack CLI clients focus on upload and streaming (tail -f) capabilities, but I would like to list and then download a file(id). Is this something you are thinking on supporting @candrholdings?

Rewrite using promise with mocha

As our user base grows and we want to deliver a more community "contribute-able" version, we plan to rewrite with Promise and automate testing using mocha. Share your ideas. Stay tuned.

Fix use of deprecated methods

@raymondkpwong Please review #35

I installed the latest version with pip and running any slack-cli command returns this error. What are the requirements?

My system, Centos 7

Python 2.7.5
pip 8.1.2 from /usr/lib/python2.7/site-packages (python 2.7)

Do I need other versions?

Error Sending File to a User

I tried this
slackcli -t xxxx-xxx-xxx-xx -a -d @user --file filename.csv -m "message"

and this
slackcli -t xxxx-xxx-xxx-xx -a -d @user --file /full/path/to/file/filename.csv -m "message"

for both I get the following error

env: node\r: Not a directory

Was getting env: node\r: Not a directory when trying to use slackcli command.

Got it working by:

vim /Users/username/.node/lib/node_modules/slack-cli/bin/cmd.js
:set ff=unix
:x

Has the DM capability not been merged into master yet?

Seems like I can't use the -d option to DM. Should I use a different branch?

Issue #14 resurfaced, and hasn't been reopened

#14 should likely have been reopened. Trying to create a new issue so that it gets attention.

It seems that posting any message with file is rejected with the error: pinning a file is not supported

Nothing else I can change seems to influence this.

Perhaps related, but less of an issue, the SLACK_TOKEN enviroment variable isn't being picked up either for me, so I cannot test without the --token xoxo-...... argument.

Error sending file to channel

When executing slackcli -h channel-name -f test.apk I get the error:

{ error: { err: 'pinning a file is not supported', message: undefined } }

I can't figure out (In Slack's documentation) how to generate a SLACK_TOKEN

I have:
App ID
Client ID
Client Secret
Signing Secret
Verification Token

I made an app in slack and can post to a channel with

curl -X POST -H 'Content-type: application/json' --data '{"text":"Hello, World!"}' https://hooks.slack.com/services/Y839CLLSF/B017HJTG2CF/c8My827hfZhs1AJzZjlSxLyD

"Pinning a file is not supported" without -p option

Hi, awesome tool! I only have one problem: I'm trying to send a file (don't know if I'm doing it right, I'm specifying the path as file name) but is shows me this error:
{ error: { err: 'pinning a file is not supported', message: undefined } }
which is really strange because I am not using the -p option for pinning the message.

Talking to a bot

I've used slack-cli successfully with my team's slack. However, I can't send a message to a bot (specifically, growthbot) that is a member of our team. I've tried both sending a direct message to the bot, and also sending a message to a channel that the bot is monitoring. The message does arrive in the chat or channel, but the bot apparently doesn't see it. Typing the exact same message by hand into the Slack app works as expected.

For example,

• As a direct message: Tell me about IBM
• As a message to a channel: @growthbot Tell me about IBM

Any thoughts why this doesn't work, and/or how to make it work?

Ability to send DM

Is it possible to currently send DM'S?

tried using -c @username but didn't seem to work, and since none of the documentation eludes to it wondering if it's even possible?

Can't get slack-cli to install

Below is the output with the errors:
npm install -g slack-cli
