Hack 44. Zip コマンドの基本

複数のファイルを zip するには

syntax: zip {.zip file-name} {file-names}

# zip var-log-files.zip /var/log/*
adding: var/log/acpid (deflated 81%)
adding: var/log/anaconda.log (deflated 79%)
adding: var/log/anaconda.syslog (deflated 73%)
adding: var/log/anaconda.xlog (deflated 82%)
adding: var/log/audit/ (stored 0%)
adding: var/log/boot.log (stored 0%)
adding: var/log/boot.log.1 (deflated 40%)
adding: var/log/boot.log.2 (deflated 42%)
adding: var/log/boot.log.3 (deflated 40%)
adding: var/log/boot.log.4 (deflated 40%)

ディレクトリやそのファイルを再帰的に zip するには

# zip -r var-log-dir.zip /var/log/
updating: var/log/ (stored 0%)
adding: var/log/wtmp (deflated 78%)
adding: var/log/scrollkeeper.log (deflated 94%)
adding: var/log/rpmpkgs.3 (deflated 68%)
adding: var/log/spooler (stored 0%)
adding: var/log/cron.2 (deflated 90%)
adding: var/log/spooler.1 (stored 0%)
adding: var/log/spooler.4 (stored 0%)
adding: var/log/httpd/ (stored 0%)
adding: var/log/rpmpkgs.1 (deflated 68%)
adding: var/log/anaconda.log (deflated 79%)
adding: var/log/secure.2 (deflated 93%)

*.zip 圧縮ファイルを unzip するには

# unzip var-log.zip
Archive: var-log.zip
inflating: var/log/acpid
inflating: var/log/anaconda.log
inflating: var/log/anaconda.syslog
inflating: var/log/anaconda.xlog
creating: var/log/audit/

以下で示すように、-v オプションを指定して、
unzip 実行中に詳細を出力します。

# unzip -v var-log.zip

展開せずに zip ファイルの内容をリストするには

# unzip -l var-log.zip
