## cmd/prepend [](https://godoc.org/github.com/rjeczalik/cmd/prepend)
Command prepend inserts data read from stdin or an input file at the
begining of the given file.
If data to prepend is passed both via stdin and input file, first the
given file is prepended with data read from stdin, then from input file.
The prepend command does not load the files contents to the memory,
making it suitable for large files. Writes issued by the prepend command
are atomic, meaning if reading from stdin or input file fails the
original file is left untouched.
*Documentation*
[godoc.org/github.com/rjeczalik/cmd/prepend](http://godoc.org/github.com/rjeczalik/cmd/prepend)
*Usage*
```
~ $ cat > preamble.txt < // Copyright (c) 2015 Your Team. All right reserved.
> // Use of this source code is governed by the X license
> // that can be found in the LICENSE file
>
> EOF
~ $ preprend -u -f preamble.txt *.go
