*GNU Core Utilitiesをインストール [#x5a5b74f]

**はじめに [#j907a7ba]

　macOSに入っているコマンドは，BSDで提供されたものなので，一部のコマンドがLinuxと動作が異なる．たとえばdateコマンドは日付けフォーマットの方法が異なるので互換性が無くて困る．
　そんな時には，GNU Core UtilitiesをMacにインストールすれば，Linuxと互換性が高くなる．この手順書ではインストールとパスの設定について説明する．

**インストール [#k3815679]

　パッケージを探す．

 MBA2014:~ ujpadmin$ brew search coreutils
 coreutils                    xml-coreutils
 MBA2014:~ ujpadmin$

インストールする．

 MBA2014:~ ujpadmin$ brew install coreutils
 ==> Downloading https://homebrew.bintray.com/bottles/coreutils-8.25.yosemite.bottle.tar.gz
 ######################################################################## 100.0%
 ==> Pouring coreutils-8.25.yosemite.bottle.tar.gz
 ==> Caveats
 All commands have been installed with the prefix 'g'.

 If you really need to use these commands with their normal names, you
 can add a "gnubin" directory to your PATH from your bashrc like:

     PATH="/usr/local/opt/coreutils/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 as well:

     MANPATH="/usr/local/opt/coreutils/libexec/gnuman:$MANPATH"

 ==> Summary
 🍺  /usr/local/Cellar/coreutils/8.25: 425 files, 8.3M

　インストール完了．コマンド群がインストールされたパスが表示されている．

**インストールされたコマンドを確認 [#c9c90859]

　ファイルを確認．

 MBA2014:~ ujpadmin$

**ファイル検索パスの設定 [#kc11833e]

　.bashrcに以下の設定を追加．

 PATH="/usr/local/opt/coreutils/libexec/gnubin:$PATH"
 MANPATH="/usr/local/opt/coreutils/libexec/gnuman:$MANPATH"


**dateコマンドを実行してみる [#bbf22281]

　Linuxで動くコマンドファイルパスを確認．

 MBA2014:ShellTest ujpadmin$ which date
 /usr/local/opt/coreutils/libexec/gnubin/date
 MBA2014:ShellTest ujpadmin$

　実行．

 MBA2014:ShellTest ujpadmin$ date -d "1 day" +"%Y/%m/%d"
 2016/07/01
 MBA2014:ShellTest ujpadmin$

　Mac用で実行．

 MBA2014:ShellTest ujpadmin$ /bin/date -d "1 day" +"%Y/%m/%d"
 usage: date [-jnu] [-d dst] [-r seconds] [-t west] [-v[+|-]val[ymwdHMS]] ...
             [-f fmt date | [[[mm]dd]HH]MM[[cc]yy][.ss]] [+format]
 MBA2014:ShellTest ujpadmin$
　文法が異なるのでエラーになる．
