Install

xpip install -U xontrib-sh
echo 'xontrib load sh' >> ~/.xonshrc
# Reload xonsh

Usage

Start a line with an exclamation point — ! — then paste the sh-compatible commands after it and run. The commands syntax will be tested in installed shells and the commands will be run in the first matching shell. By default was set two shells: bash and sh. You can add other to the list of shells.

The commands will be executed in the environment that will be inherited from current but if the commands modify the environment there will no changes in source xonsh environment.

To set the list of shells use environment variable before loading the xontrib:

$XONTRIB_SH_SHELLS = ['bash', 'sh']  # default
xontrib load sh

Use cases

The main use case

The main use case of xontrib-sh is when you copy and paste the sh-commands from some article or instruction and this commands are environment agnostic and you want to run it without rewriting it on xonsh or run sh-shell.

For example you've found xxh local snippet:

XH=~/.xxh \
 && XD=https://github.com/xxh/xxh-portable/raw/master/result/xxh-portable-musl-alpine-Linux-x86_64.tar.gz \
 && mkdir -p $XH && cd $XH \
 && ( [[ -x $(command -v curl) ]] && curl -L $XD || wget -O- $XD ) | tar zxf - xxh \
 && echo 'Usage: ./xxh local [+s xonsh/zsh/fish/osquery/bash]'

It's bash and it's environment agnostic and you hesitate how xonsh will execute this. Just start with ! and paste this commands. As result you've installed xxh local and stayed in xonsh.

One line: brace expansion

! echo 01.{05..10}

bash:
01.05 01.06 01.07 01.08 01.09 01.10

Many lines: for loop

! for i in 1 2 3
do
   echo $i
done

bash:
1
2
3

Known issues

If you want to use many shells the syntax checking is not determine the shell exactly right. If you have bash and fish in the list of shells the short fish command may be determined as bash command. As result the command will be failed. Use multi shell list carefully.

Bad example:

$XONTRIB_SH_SHELLS = ['bash', 'fish']
xontrib load sh
# Run fish command:
! set -U EDITOR vim
# bash: line 0: set: -U: invalid option

If you have an idea how to improve the shell detection pull requests are welcome!
