itermblast

Ever wish you could open dozens of parallel SSH sessions using one command within seconds? This is for you.

itermblast_ssh.sh

This script accepts the path to a file that contains a list of hostnames, then opens up the corresponding number of sessions in iTerm2 and ssh into each individual host.

The file passed in should contain just a list of server hostnames of IPs separated by newlines. No other information should be in the file.

Requirements:

  • Mac
  • iTerm2

Example hostfile:

host1.example.com
host2.example.com

Example: ./itermblast_ssh.sh <PATH_TO_HOST_FILE>

itermblast_aws.sh

The script requires three variables:

  • -profile
  • -region
  • -name_filter

The script then uses AWS cli to get a list of instances matching the name filters (--filters "Name=tag:Name,Values=${name_filter}"), opens up the corresponding number of sessions in iTerm2, and use SSM to open a session to each individual host.

Required components:

Example: ./itermblast_aws.sh -profile <PROFILE_NAME> -region <AWS_REGION_NAME> -name_filter <FILTER_STRING>
