class-dumpのわな

tar.bz2を持ってきて:

[22:35]marble:~/work<110> tar jxf ~/Desktop/class-dump-3.1.2.tar.bz2 
tar: This does not look like a tar archive
tar: Skipping to next header
tar: Archive contains obsolescent base-64 headers
tar: Error exit delayed from previous errors

あれ?

[22:36]marble:~/work<112> file ~/Desktop/class-dump-3.1.2.tar.bz2
/Users/takesi/Desktop/class-dump-3.1.2.tar.bz2: bzip2 compressed data, block size = 900k

bzip2だよなあ.. とりあえず bunzipして中身を見るか:

[22:36]marble:~/work<114> bunzip2 ~/Desktop/class-dump-3.1.2.tar.bz2
[22:36]marble:~/work<115> file ~/Desktop/class-dump-3.1.2.tar 
/Users/takesi/Desktop/class-dump-3.1.2.tar: gzip compressed data, from Unix, max compression

げ、そういう落ちですか! それなら tar.gz.bz2 ってファイル名にしろよ!

[22:36]marble:~/work<116> tar xzf ~/Desktop/class-dump-3.1.2.tar 
[22:41]marble:~/work<118> lf class-dump-3.1.2/
class-dump-3.1.2:
README      class-dump* src/        

展開できました。自己適用してみると:

[22:42]marble:~/work<122> class-dump-3.1.2/class-dump class-dump-3.1.2/class-dump
