# fcmp - compare file identity
A shell utils that compares files for identity with `mmap()` and `memcmp()`.
# Usage
`fcmp` produces no output, but success is indicated by its return code.
```shell
$ fcmp file1 file2 && echo "Equal!"
```
| Code | Meaning |
|------|--------------------------------------------------------------|
| 0 | The files are equal |
| 1 | The files are unequal |
| 2 | The files have unequal lengths, and therefor must be unequal |
| -1 | There was an error |
Therefor you can use this in shell scripts easily:
``` shell
# Example
if fcmp "$1" "$2"; then
echo "Files are equal!"
else
echo "Files are not equal!"
fi
```
