bshell is a Bourne Shell interpreter from the Schily-Tools collection, providing a traditional POSIX-compatible shell environment. It executes commands read from standard input, command strings, or script files.
The Bourne Shell is the original Unix shell written by Stephen Bourne at Bell Labs. This implementation maintains compatibility with the classic shell behavior while running on modern systems.

-c command

Execute the specified command string

Start as a restricted shell, limiting certain operations for security

Treat unset variables as errors and exit

Print shell input lines as they are read (verbose mode)

Print commands and arguments as they are executed (debug mode)

The bshell command is part of the Schily-Tools package and may not be installed by default on most Linux distributions. Most systems use bash or dash as /bin/sh for Bourne shell compatibility.

The original Bourne Shell was developed by Stephen Bourne at Bell Labs and first appeared in Version 7 Unix in 1979. It replaced the Thompson shell and became the foundation for subsequent shells including ksh, bash, and zsh. The Schily-Tools implementation by Jörg Schilling provides a modern port of the classic Bourne Shell.
