shellrosetta 1.1.0

Translate Linux/Bash commands to PowerShell and vice versa, with flag and pipeline support.

ShellRosetta

Translate Linux/Bash commands to PowerShell and vice versa—flags, pipes, networking, and more.

---

What is ShellRosetta?

ShellRosetta is a cross-platform CLI tool for developers, sysadmins, and anyone switching between Windows and Linux.

It instantly translates commands—including flags and arguments—between Linux/Bash and PowerShell. No more flipping between cheat sheets or Stack Overflow!

---

Features

• 🖥️ Interactive Shell Mode! Open ShellRosetta as a REPL and translate commands live, just like in a real shell.
• 🔄 Bi-directional translation: Linux ↔ PowerShell, with accurate mappings for real-world scenarios.
• 🏷️ Flag and multi-flag aware: Understands combos like ls -alh, rm -rf, etc.
• 🔗 Pipeline support: Handles piped commands (e.g. ls -l | grep foo).
• 🌐 Networking and system commands: Supports ping, curl, Get-NetTCPConnection, and many more.
• 📋 Extensive mappings: Permissions, archiving, users, process management, environment variables, I/O redirection, and more.
• 🚦 Helpful notes: Outputs usage tips or warnings if there's no direct translation or if a flag behaves differently.
• 🧩 Easily extensible: Add or edit mappings in mappings.py—grow as you learn!
• ⚡ Ready for shell aliases & tab-completion: Bash/Zsh completion script included.

Quickstart

Clone and install locally:

git clone https://github.com/sdirishguy/shellrosetta.git cd shellrosetta pip install . Usage:

shellrosetta lnx2ps "ls -alh | grep error" shellrosetta ps2lnx "Get-ChildItem -Force | Select-String error" Or test before installing:

python -m shellrosetta.cli lnx2ps "ls -alh | grep error" python -m shellrosetta.cli ps2lnx "Get-ChildItem -Force | Select-String error" (Optional) Add aliases to your shell:

echo "alias lnx2ps='shellrosetta lnx2ps'" >> ~/.bashrc echo "alias ps2lnx='shellrosetta ps2lnx'" >> ~/.bashrc source ~/.bashrc (Optional) Enable tab-completion: Copy shellrosetta/autocomplete.sh somewhere (or use directly from the repo), then add this to your ~/.bashrc or ~/.zshrc:

source /path/to/shellrosetta/autocomplete.sh Reload your shell:

source ~/.bashrc

or

source ~/.zshrc Now you get tab completion for commands and flags!

Interactive Shell Mode

Run with no arguments for a live translation shell!

shellrosetta

You'll be prompted for your translation mode (lnx2ps or ps2lnx). Enter commands and see translations instantly, switching modes at any time with mode or exit with exit.

ShellRosetta: Linux ↔ PowerShell CLI Command Translator
Author: David Donohue
Repo: github.com/sdirishguy/shellrosetta
=================================================================
Welcome to ShellRosetta Interactive Mode!
Type 'exit' to quit, or 'mode' to switch translation direction.
Mode [lnx2ps/ps2lnx] (or 'exit'): lnx2ps
Type your LNX2PS commands below. Type 'mode' to switch, 'exit' to quit.

> ls -alh | grep foo

--- Translation ---
PowerShell Equivalent:
  Get-ChildItem -Force | Format-List # [Human-readable file sizes not natively available.] | Select-String foo
-------------------

> rm -rf /tmp
--- Translation ---
PowerShell Equivalent:
  Remove-Item -Recurse -Force /tmp
-------------------

> mode
Mode [lnx2ps/ps2lnx] (or 'exit'): ps2lnx
Switched to PS2LNX mode.

> Get-Process
--- Translation ---
Linux Equivalent:
  ps aux
-------------------

> exit
Goodbye!

Bash/Zsh Tab Completion

Speed up your workflow with tab-completion for top-level commands and common flags.

1. Copy shellrosetta/autocomplete.sh into your home directory, or reference it from your project.

2. Add this to your ~/.bashrc or ~/.zshrc:

source /path/to/shellrosetta/autocomplete.sh Reload your shell:

source ~/.bashrc # or source ~/.zshrc

Now, typing lnx2ps l or ps2lnx G will auto-complete common commands and flags!

Example autocomplete script (shellrosetta/autocomplete.sh):

# Bash/Zsh completion for ShellRosetta
_shellrosetta_complete() {
  local cur prev opts lnxflags psflags
  COMPREPLY=()
  cur="${COMP_WORDS[COMP_CWORD]}"
  prev="${COMP_WORDS[COMP_CWORD-1]}"
  opts="ls rm cp mv grep find cat ping ifconfig netstat traceroute curl wget hostname nslookup dig"
  lnxflags="-a -l -h -R -r -f -v"
  psflags="-Force -Recurse -Verbose | Format-List -CaseSensitive:\$false"

  if [[ ${COMP_CWORD} -eq 1 ]]; then
    COMPREPLY=( $(compgen -W "lnx2ps ps2lnx" -- "${cur}") )
    return 0
  fi
  if [[ ${COMP_CWORD} -eq 2 ]]; then
    COMPREPLY=( $(compgen -W "${opts}" -- "${cur}") )
    return 0
  fi
  if [[ ${COMP_WORDS[1]} == "lnx2ps" ]]; then
    if [[ ${COMP_WORDS[2]} == "ls" || ${COMP_WORDS[2]} == "rm" || ${COMP_WORDS[2]} == "cp" || ${COMP_WORDS[2]} == "mv" ]]; then
      COMPREPLY=( $(compgen -W "${lnxflags}" -- "${cur}") )
      return 0
    fi
  elif [[ ${COMP_WORDS[1]} == "ps2lnx" ]]; then
    if [[ ${COMP_WORDS[2]} =~ (Get-ChildItem|Remove-Item|Copy-Item|Move-Item|Select-String) ]]; then
      COMPREPLY=( $(compgen -W "${psflags}" -- "${cur}") )
      return 0
    fi
  fi
}
complete -F _shellrosetta_complete lnx2ps
complete -F _shellrosetta_complete ps2lnx

Examples

shellrosetta lnx2ps "ls -alh | grep foo"

➔ Get-ChildItem -Force | Format-List # [Human-readable file sizes not natively available.] | Select-String foo

shellrosetta lnx2ps "rm -rf /var/tmp"

➔ Remove-Item -Recurse -Force /var/tmp

shellrosetta lnx2ps "tar -czvf backup.tar.gz myfolder/"

➔ Compress-Archive # [Outputs .zip, not .tar.gz. For gzip, use third-party modules or 7-Zip.]

shellrosetta ps2lnx "Get-ChildItem -Force | Format-List"

➔ ls -la

Supported Command Areas Filesystem: ls, rm, cp, mv, touch, cat, ln, mkdir, cd, pwd, etc.

See mappings.py for full details.

How the Logic Works Checks for an exact command or command+flag mapping first (fast and accurate).

If not found, falls back to a flexible per-command flag parser for real-world combos.

Provides notes or warnings if there is no direct translation or usage caveat.

Handles piped commands and reconstructs them for the target shell.
