# realcsh.c(1)

A shell for running C code

## NAME

realcsh.c - A shell for running C code

## SYNOPSIS

**realcsh.c \[***gcc options***\]**

## DESCRIPTION

**realcsh.c** is an interactive shell that runs C source code. A line of input is handled as a line in **main()** function, and the resulting C code is compiled, and executed.

If a line starting with **#** such as  **#include \<stdio.h\>** is entered, it is added to every code after that at the start of sourcecode.

The list of such lines can be seen with **##**

## EXAMPLES

The following is an example session

```
$ realcsh.c
REAL csh: printf("hello world\n");
hello world
REAL csh: system ("pwd");
/home/dancer/
```

## INTERNALS

The following is how the C code looks like.

```
/*BINFMTC:
*/
#include <stdlib.h>
#include <unistd.h>
#include <stdio.h>
int main(int argc, char ** argv)
{
input-line
return 0;
}
```
