bash-llvm is Bash implementation built for modern age. Built from the ground up with security and performance in mind.
bash-llvm has an about a 20x runtime speed improvement over GNU Bash, read
the release blog post for more details!
I feel kind of silly writing a syntax example for Bash but here we are.
To run a program it's as simple as writing out its name.
fastfetch
# will run fastfetch
Some programs are special and interact nicely with your shell.
echo "Hello World"
# prints "Hello World"
If you want to run another program after the first one completes you can use &&.
termdown 20m && poweroff
# will poweroff your machine after 20 minutes while still being cancelable
There's a lot more features like if statments, for loops, while loops, ranges, piping but that's all for the basic usage.
If you would like the quick easy way out to install BASH-LLVM on Linux, run the installer
bash -c "$(COLUMNS=50 curl https://raw.githubusercontent.com/FoxMoss/llsh-installer/refs/heads/main/install.sh -#)"Code is fully auditable at llsh-installer.
Requirements:
- CMake 3.5 or above
- A C & C++ compiler C++23 support needed
- Ninja or make if you know how to use it
- patch
- git
All other dependencies are handled by CMake and CPM, and fetched in at build time.
These should be relatively easy to find on Arch Linux and Alpine Linux (edge repos)
mkdir -p build
cd build
cmake .. -DCMAKE_BUILD_TYPE=Release -GNinja
ninja
sudo ninja install
