# VX

VX is a BSD-oriented multicall utility for Linux.

It bundles a growing set of FreeBSD-derived userland tools into a single `vx` binary, with applets selected by `argv[0]` or by subcommand.

## Included applets

- `patch`
- `diff`, `cmp`, `diff3`, `sdiff`
- `which`
- `gzip`, `gunzip`, `zcat`, `gzcat`, `uncompress`
- `grep`, `egrep`, `fgrep`, `rgrep`
- `find`
- `xargs`
- `lspci`, `setpci`

## Build

VX uses Meson.

```text
meson setup builddir
meson compile -C builddir
meson test -C builddir
```

To build only selected utilities:

```text
meson setup builddir -Dutils=grep,find,xargs
```

The default is `-Dutils=all`.

## Run

You can invoke applets either through the multicall binary:

```text
./builddir/vx grep pattern file
./builddir/vx find . -name '*.c'
```

or via installed symlinks such as `grep`, `find`, or `patch`.

## Notes

- The project force-includes `src/compat-headers/compat.h` to provide Linux compatibility shims for BSD userland code.
- Some behavior is intentionally BSD-flavored, even where GNU tools differ.
