# GoPatch

*Tool to easily patch binary files.*

## Build

To build the tool:

```

$ go build main.go

$ strip main

$ mv main /usr/bin/gopatch

```

## Usage

To patch a binary:

```

$ gopatch  

```

## Patchfile

A patchfile should follow the below syntax:

```

1 
:

2 0x

```


Example:

```

1 0x12345678:

2 0x5058

3 0xe9

4

5 0x23456789:

6 0x45

```

This patches will happen at specified binary addresses, and the bytes will be

written in order.

Here is an example of gopatch being used:

`patch.txt`

```

1 0x0:

2 0x67

3 0x6869

```

```

$ xxd binary

00000000: 6162 630a 6465 660a                      abc.def.

$ gopatch binary patch.txt

$ xxd binary

00000000: 6768 690a 6465 660a                      ghi.def.

```
