slacktee is a bash script that works like tee command. Instead of writing the standard input to files, slacktee posts it to Slack.

slacktee uses curl command to communicate with Slack.

Please execute install.sh as shown below:

bash ./install.sh

install.sh copies slacktee.sh to /usr/local/bin and sets executable permission. After the installation, interactive setup starts automatically.

Before start using slacktee, please set following variables in the script configuration file. slacktee reads the global configuration (/etc/slacktee.conf) first, then reads your local configuration (~/.slacktee). You can set up your local configuration file using interactive setup mode (--setup option).

For more details about tokens, visit Slack's API page.

webhook_url=""      # Incoming Webhooks integration URL. See https://my.slack.com/services/new/incoming-webhook
upload_token=""     # The user's API authentication token, only used for file uploads. See https://api.slack.com/#auth
channel=""          # Default channel to post messages. You don't have to add '#'.
tmp_dir="/tmp"      # Temporary file is created in this directory.
username="slacktee" # Default username to post messages.
icon="ghost"        # Default emoji to post messages. You don't have to wrap it with ':'. See http://www.emoji-cheat-sheet.com.

Feed input to slacktee through the pipe.

If you'd like to post the output of ls command, you can do it like this.

ls | slacktee.sh

To post the output of tail -f command line by line, use -n option.

tail -f foobar.log | slacktee.sh -n

To post the output of find command as a file, use -f option.

find /var -name "foobar" | slacktee.sh -f

You can specify channel, username, icon, title, and link too.

ls | slacktee.sh -c "general" -u "slacktee" -i "shipit" -t "ls" -l "http://en.wikipedia.org/wiki/Ls"

Of course, you can connect another command with pipe.

ls | slacktee.sh | email "ls" [email protected]

You may want to integrate slacktee into Travis-CI in order to send additional logging information to your Slack channel. In this case, it is recommended that you do not expose your Incoming WebHook URL and API authentication token as plaintext values inside your slacktee.conf file.

Instead, use the encrypt command of the Travis client to set the SLACKTEE_WEBHOOK and SLACKTEE_TOKEN environment variables, and leave the webhook_url and upload_token values in your slacktee.conf empty. When slacktee runs, it will give priority to the environment variables, which Travis-CI will decrypt and set automatically during the build process. In this way those two values are kept secure.

Modify slacktee.conf

webhook_url=""
upload_token=""
channel="Travis-CI"
tmp_dir="/tmp"
username="slacktee"
icon="ghost"

Add the encrypted environment variables to the .travis.yml file in your git repository

travis encrypt SLACKTEE_WEBHOOK='https://hooks.slack.com/services/afternoonTEE/BMP2vsT72/ohNoDontTellUs' --add
travis encrypt SLACKTEE_TOKEN='yoho-0987654321-1234567890-4488116622-abc123' --add

Looking at your travis.yml you will now see the following added

env:
  global:
  - secure: 2YZabH8+UdzqyBWckojRDP9uudnCSYyxOOx1y85el69YdHwLDMD+dt49rAgIrmCWsWCWpUZ0ZRWV8vU2VFMffIhmikiqG7VoKHuN5PyY8qBwr9hq/ZI8gdwgjgfRIGtv/U89BTjMmc1g/6nJkSvMtiSUSK3Lopg0JCyuZsiyhzs=
  - secure: TKpohmywdOneQkqGxJiF+S1N8oCdTWWGsXgjzNXWSvb23KDtvGq/W2SpWdFdwEHC9Y8NymoAPYRSW8MUQoiJ7NaQ1eZQuyx6/orjHpIgqiAuHrOSaMagzpKVG6Gtb87qDgov65ZOasyex1OtPQdfFtZBX67B6IVXkRPV+IA/+UX=

An example travis.yml section using slacktee may look like:

after_failure:
- ls /path/to/build | ./slacktee.sh -t "$TRAVIS_REPO_SLUG $TRAVIS_JOB_NUMBER build directory"
- cat /path/to/some.log | ./slacktee.sh -t "$TRAVIS_REPO_SLUG $TRAVIS_JOB_NUMBER some.log"
