# gitbrute(1)

brute-force a git commit hash to a given prefix

## NAME

gitbrute - brute-force a git commit hash to a given prefix

## SYNOPSIS

**gitbrute** *-prefix* deadbeef

## DESCRIPTION

**gitbrute** amends the top commit in a git repository, altering commit-time and author-time to have the commit's hash start with the given prefix.

## OPTIONS

- \-prefix 000000

  Specifies the hash prefix to search for.  Obviously, the expected time required to find it grows exponentially with the prefix's length.

- \-force true

  If the current commit already matches the prefix, it will be replaced by another one.

- \-cpus 64

  Specifies the level of parallelism; defaults to number of online processors at startup.
