meng

A small script I built to stop retyping the same ssh/scp commands all day.

Setup

git clone https://github.com/mengdotzip/Meng-Script.git
cd Meng-Script

To use it from anywhere without the ./:

mkdir -p ~/.local/bin
cp meng.sh ~/.local/bin/meng

If ~/.local/bin isn't in your PATH yet, add this to your .bashrc or .zshrc:

export PATH="$HOME/.local/bin:$PATH"

Tab completion

• bash

mkdir -p ~/.local/share/bash-completion/completions
cp meng-completion.bash ~/.local/share/bash-completion/completions/meng
source ~/.local/share/bash-completion/completions/meng

• zsh

mkdir -p ~/.local/share/zsh/site-functions
cp _meng ~/.local/share/zsh/site-functions/_meng

Add to ~/.zshrc if not already there:

fpath=(~/.local/share/zsh/site-functions $fpath)
autoload -Uz compinit && compinit

Reload without restarting your shell:

unfunction _meng 2>/dev/null; autoload -Uz _meng

Usage

# save a server
meng add prod admin@192.168.1.100:/opt/app/

# save a server with a custom SSH port
meng add staging admin@192.168.1.100:/opt/app/ -p 2222

# or just SSH in normally, then save it after
ssh admin@192.168.1.100
meng ingest prod !!

# ingest an SSH command that uses a custom port
ssh -p 2222 admin@192.168.1.100
meng ingest staging !!

# connect / copy / deploy (port is used automatically)
meng ssh    prod
meng scp    prod build/myapp
meng scp    prod dist/ -r
meng deploy prod myapp

# scripts
meng script add backup ~/scripts/rclone_backup.sh
meng run backup

# scripts with parameters
#  - store fixed default args, add more at call time:
meng script add setup-env ~/scripts/setup-code-env.sh vscode-box
meng run setup-env                      # runs: setup-code-env.sh vscode-box
meng run setup-env remcsc               # runs: setup-code-env.sh vscode-box remcsc
#  - need the call-time args somewhere other than the end? use a {} placeholder:
meng script add setup-env ~/scripts/setup-code-env.sh --box vscode-box {} --verbose
meng run setup-env remcsc               # runs: setup-code-env.sh --box vscode-box remcsc --verbose

# see everything
meng list

Config

Everything lives in ~/.config/meng/ — created automatically on first run.

~/.config/meng/
├── aliases # your servers
└── scripts # your script shortcuts

Plain text, one entry per line. Worth backing up or sticking in a dotfiles repo.

All commands

meng ssh <alias>
meng scp <alias> <file> [-r] [-p <path>]
meng deploy <alias> <file>
meng info <alias>

meng add <name> <user@host:/path> [-p <port>]
meng remove <name>
meng ingest <name> [ssh] <user@host>
meng list

meng run <name> [args...]
meng script add <name> <path> [args...]
meng script remove <name>

-p on scp with a leading / replaces the alias path entirely, without one it appends to it. -p <port> on add sets a custom SSH/SCP port, stored in the alias and applied automatically. run appends any args you pass after the script's stored default args; a {} placeholder in the stored args is replaced by them instead. Scripts run via their own shebang (or sh if they have none). deploy assumes a Go project and runs go build first.
