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 command syntax will be tested in installed shells (bash, zsh, fish, sh) and the commands will be run in the first matching shell.

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.

Note! The syntax checking is not determine the shell exactly right and pull requests are welcome! The short commands may be determined as bash commands but it's fish or zsh. As result the command will be failed. Use this carefully and if you know that you need only bash just remove the zsh and fish from the list as described below.

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 (bash syntax)

! echo 01.{05..10}

bash:
01.05 01.06 01.07 01.08 01.09 01.10

Many lines: for loop (zsh syntax)

! for x (1 2 3); do 
  echo $x; 
done

for x (4 5 6); do 
  echo $x; 
done

zsh:
1
2
3
4
5
6

Set certain shell for any commands

$XONTRIB_SH_SHELLS = ['bash']
