#cli My base cli setup.

Installation

Setup symlinks to config files in this repo:

$: ./install
  • Use the -b <extension> flag to save a backup of the current config file (if one already exists).
  • gitconfig will not be installed by the script.

Bash

My bashrc follows me everywhere; thus I include darwin and linux specific functionality in my bashrc. I store machine-specific stuff in .bash_profile (not included in this repo) and super secret stuff in a .bash_private file.

Prompt

I have hacked my own prompt, but it is probably smarter to use the prompt in git contrib.

VI Mode

I use vi key bindings where possible: the bashrc file will set -o vi for editing the command line and the inputrc file will activate vi mode for other readline prompts (e.g. psql).

bin

Bin files are automatically added to the path if you're using the .bashrc file in this repo.

update

A script I use to update key repos regularly. To use, just set the $UPDATE_LIST environment variable to contain a list of repos to update.

Example:

  $: export UPDATE_LIST="$HOME/repos/cli $HOME/.emacs.d"
  $: update
  Updating /home/sbaxter/repos/cli
  UNABLE TO UPDATE (DIRTY)
  Updating /home/sbaxter/.emacs.d

daily

Execute a script on login, but no more than once per day. The -f option flag will execute only on the first login of the day. Example from my .bash_profile:

  daily -f diskusage
  daily -f update > /dev/null && echo
  daily -f brew update && echo && brew outdated && echo
  daily backup

Note: anacron may be a better option for stuff like this: write the output to a file and cat the results on login.

backup

A script I use to backup key files to AWS s3. To use, just set the $BACKUP_LIST environment variable to contain a list of files and directories to backup.

Example on Mac OSX:

  [Ptolemy:/~]: export BACKUP_LIST="$HOME/.bash_profile"
  [Ptolemy:/~]: backup
  upload: .backup/.bash_profile to s3://my-backups/Ptolemy/.bash_profile
  upload: .backup/latest.txt to s3://my-backups/Ptolemy/latest.txt
  upload: .backup/brewlist.txt to s3://my-backups/Ptolemy/brewlist.txt

Note: $HOME/ssh/config is automatically backed up by this script; a list of brew packages is also stored on Mac OSX.

AWS scripts

cfn

  • View stack status:
  $: cfn my-app
  my-app     UPDATE_COMPLETE
  • Retrieve a stack output or parameter:
  $: cfn -o ELBDNS my-app
  my-app-XXXXXXXXX.us-east-1.elb.amazonaws.com

  $: cfn -p Stage my-app
  production
  • validate a cloudformation template:
  $: cfn -t cfn-template.json

  A client error (ValidationError) occurred when calling the ValidateTemplate operation: Template format error: JSON not well-formed. (line 1, column 3)
  • Run cfn -h for more options.

ec2

  • Return ec2 public dns by Tag (verbose instance information with -v):
  $: ec2 my-app
  ec2-XX-XX-XXX-XXX.compute-1.amazonaws.com
  • Return ec2 public dns by instance-id (verbose instance information with -v):
  $: ec2 -i i-bc9af510
  ec2-XX-XX-XXX-XXX.compute-1.amazonaws.com
  • If jump is available, you can jump to the server through a jump host in one command:
  $: ec2 -j my-app
  ..ssh session..
  • Alternatively, you can ssh directly:
  $: ssh $(ec2 my-app | head -n 1)
  • Run ec2 -h for more options.
