## Install

Download file [`GNU_Brewfile`](#file-gnu_brewfile), then run:

```
brew bundle --file GNU_Brewfile
```

## Configuration

All commands have been installed with the prefix `g`.

If you need to use these commands with their normal names, you
can add some `gnubin` directory to your PATH from your `~/.bashrc` or `~/.bash_profile` like:
```
export PATH="/usr/local/opt/binutils/bin:$PATH"
export PATH="/usr/local/opt/coreutils/libexec/gnubin:$PATH"
export PATH="/usr/local/opt/ed/libexec/gnubin:$PATH"
export PATH="/usr/local/opt/findutils/libexec/gnubin:$PATH"
export PATH="/usr/local/opt/gawk/libexec/gnubin:$PATH"
export PATH="/usr/local/opt/gnu-indent/libexec/gnubin:$PATH"
export PATH="/usr/local/opt/gnu-sed/libexec/gnubin:$PATH"
export PATH="/usr/local/opt/gnu-tar/libexec/gnubin:$PATH"
export PATH="/usr/local/opt/gnu-which/libexec/gnubin:$PATH"
export PATH="/usr/local/opt/grep/libexec/gnubin:$PATH"
```

Additionally, you can access their man pages with normal names if you add
the `gnuman` directory to your MANPATH from your `~/.bashrc` or `~/.bash_profile` as well:
```
export MANPATH="/usr/local/opt/binutils/share/gnuman:$MANPATH"
export MANPATH="/usr/local/opt/coreutils/libexec/gnuman:$MANPATH"
export MANPATH="/usr/local/opt/ed/libexec/gnuman:$MANPATH"
export MANPATH="/usr/local/opt/findutils/libexec/gnuman:$MANPATH"
export MANPATH="/usr/local/opt/gawk/libexec/gnuman:$MANPATH"
export MANPATH="/usr/local/opt/gnu-indent/libexec/gnuman:$MANPATH"
export MANPATH="/usr/local/opt/gnu-sed/libexec/gnuman:$MANPATH"
export MANPATH="/usr/local/opt/gnu-tar/libexec/gnuman:$MANPATH"
export MANPATH="/usr/local/opt/gnu-which/libexec/gnuman:$MANPATH"
export MANPATH="/usr/local/opt/grep/libexec/gnuman:$MANPATH"
```

## gdb

gdb requires special privileges to access Mach ports.

You will need to codesign the binary. For instructions, see [here](https://sourceware.org/gdb/wiki/BuildingOnDarwin).

On 10.12 (Sierra) or later with SIP, you need to run this:
```
echo "set startup-with-shell off" >> ~/.gdbinit
```
