like gofmt but for c... and using astyle

gistfile1.sh

#!/usr/bin/env bash
# mostly from http://word.bitly.com/post/31921713978/static-analysis
function cfmt {
  if [[ $# -ne 1 ]]; then
    echo "Usage: cfmt <file>"
  else
    astyle \
      --style=1tbs \
      --lineend=linux \
      --convert-tabs \
      --preserve-date \
      --pad-header \
      --indent-switches \
      --align-pointer=name \
      --align-reference=name \
      --pad-oper \
      --suffix=none \
      $1
  fi
}

uses 1TBS style formatting

#include <stdio.h>

int main(int argc, char *argv[])
{
    if (true) {
        printf("Hello World!\n");
    }
    return 0;
}
