=============

**goinsu** - a simple `su` which doesn't mess with TTY and other stuff. It is as simple as "Hey, run this program as this user".

## Why?

```

$ docker run -it --rm ubuntu:trusty su -c "ps aux"

USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND

root         1  7.0  0.0  46644  2628 pts/0    Ss+  19:07   0:00 su -c ps aux

root         7  0.0  0.0  15584  2100 ?        Rs   19:07   0:00 ps aux

$ docker run -it --rm ubuntu:trusty sudo ps aux

USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND

root         1  7.0  0.0  46028  3044 pts/0    Ss+  19:07   0:00 sudo ps aux

root         6  0.0  0.0  15584  2140 pts/0    R+   19:07   0:00 ps aux

$ docker run -it --rm -v`pwd`/goinsu:/usr/bin/goinsu ubuntu:trusty goinsu root ps aux

USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND

root         1  0.0  0.0   7152   852 pts/0    Rs+  19:08   0:00 ps aux

```

## Why reinvent gosu?

**goinsu** does the same thing but in 10KB (well, 50KB if compiled as a static executable) instead of 1.8MB.

## Why reinvent su-exec?

**goinsu** is written in the D programming language, which is a high-level programming language with metaprogramming, CTFE, and other cool things you can't find in C.

## betterC?

Yep. goinsu written in a subset of the D programming language, called betterC. Just google for it, ya' know.

## Alternatives

You can use `gosu` or `su-exec`, but they aren't as cool as **goinsu**.
