Set Up

Clone the repository and navigate to it

git clone https://github.com/Lab-Brat/linux_scripts.git

Then, install virtual enironment and build the app with setup.py

python -m venv .venv
source .venv/bin/activate
python -m pip install .
ladm --help

Using

bash

Show available Bash scripts or run them. Examples:

# Show Bash scripts
ladm bash show

# Show Bash scripts
ladm bash --run <script.sh>

ipfind

Use locally installed whois command to find information about IP provider and parse the output. Examples:

# find IP provider info of address 8.8.8.8
ladm ipfind -i 8.8.8.8

sensfind

Do a recursive search on a specified directory to look for IP addresses and passwords. Might come in handy to check sensitive info in a git repository before pushing it. Examples:

# Search for sensitive info in current directory
ladm sensfind -p ./

separator

Create a line separator for scripts. Default value is 79, which is recommend line length for Python code. Examples:

# Print a separator line titled 'florples', length = 79
ladm separator -t 'flroples'

# Print a separator line titled 'florples', length = 20
ladm separator -t 'flroples' -n 20

ssh

A tool that configures ~/.ssh/config via a yaml file that support editing it via CLI instead of doing it manually.

Configuration file is stored in ~/.ladm/ssh_conf.yaml, and looks something like this:

general_settings:
- ServerAliveInterval 120
- IdentitiesOnly yes
- StrictHostKeyChecking no
identities:
  personal:
  - User labbrat
  - IdentityFile /path/to/personal_key
  root:
  - User root
  - IdentityFile /path/to/root_key
pairings:
  host1:
    host:
    - hostname-1.com
    - hostname-2.com
    identity: personal
    options: []
  host2:
    host:
    - hostname-3-*.com
    identity: root
    options:
    - Port 69

And here are some example of how to use it:

# overwrite ~/.ssh/config with yaml configuraion
ladm ssh -a

# update identity of a host and write ssh/config
ladm ssh -u 'host2 identity x personal' -a

# show yaml config
ladm ssh -s
