RAR for Linux のインストールと使い方

WinRARのLinux版。

公式サイト
http://www.rarlab.com/

インストール

インストールするには、公式サイトからファイルをダウンロードして展開するだけ。

コマンドライン版を試してみる。

$ wget http://www.rarlab.com/rar/rarlinux-5.0.1.tar.gz

展開して中身を確認

$ tar zxf rarlinux-5.0.1.tar.gz
$ cd rar
$ ls
acknow.txt  default.sfx*  license.txt  makefile  order.htm  rar*  rar.txt  rar_static*  rarfiles.lst  readme.txt  unrar*  whatsnew.txt

license.txt にライセンスについて記載がある。

40日間は評価期間、以降はライセンスを購入して下さいというのは、Win版と同じと思われる。

rar/unrarコマンドを/usr/local/bin 以下などにコピーして利用する。


とりあえずヘルプを見ようとコマンドを実行してみるとエラー発生

./rar: error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory

ライブラリが足りない模様。

「libstdc++-devel」をyumでインストールすれば良いものの、32bit/64bitがある。

libstdc++-devel.i686 : Header files and libraries for C++ development
libstdc++-devel.x86_64 : Header files and libraries for C++ development

rarで必要とされているのは32bitのようなので、64bitOSの場合は明示的にアーキテクチャを指定する。

# yum install libstdc++-devel.i686   ←「.i686」を省略すると x86_64 のパッケージが対象となる

ヘルプを確認
