Windowsで解凍しなくてはならない場合のパスワード付きZIPの作り方(debian)

■Windowsで解凍しなくてはならない場合のパスワード付きZIPの作り方(debian)

$sudo apt-get install -y zip unzip

■圧縮、確認、解凍

$ zip -P password sample.zip sample
updating: sample (deflated 43%)

$ zipinfo sample.zip 
Archive:  sample.zip
Zip file size: 369 bytes, number of entries: 1
-rw-r--r--  3.0 unx      313 TX defN 14-Aug-11 21:42 sample
1 file, 313 bytes uncompressed, 179 bytes compressed:  42.8%

$ unzip sample.zip 
Archive:  sample.zip
[sample.zip] sample password: 
replace sample? [y]es, [n]o, [A]ll, [N]one, [r]ename: y
  inflating: sample                  

■中身の確認

$ cat sample
 for n in `seq 1 21`;do \
    for m in `seq 1 21`;do \
      if [ $n -eq $m ];then \
        echo -n "XXXX"; \
      else \
        echo "$m $n" | awk '{if((22-$1)==$2){printf "XXXX"}else{printf "%04d",$1*$2}}';fi | \
          sed s/"[0-9][0-9][0-9][0-9]"/"  "/g | sed s/"XXXX"/" X"/g; \
    done;echo; \
  done

$ /bin/bash sample

 X                                       X

■複数ファイルの場合、デフォルトが追加なので、
 以下のように出来る。

$ /bin/bash sample > sample.log

$ du sample*
4	sample
4	sample.log

$ for list in sample*;do zip -P password sample.zip "$list";done
  adding: sample (deflated 43%)
  adding: sample.log (deflated 90%)

$ zipinfo sample.zip 
Archive:  sample.zip
Zip file size: 638 bytes, number of entries: 2
-rw-r--r--  3.0 unx      313 TX defN 14-Aug-11 21:42 sample
-rw-r--r--  3.0 unx      903 TX defN 14-Aug-11 21:44 sample.log
2 files, 1216 bytes uncompressed, 272 bytes compressed:  77.6%

■シェルの複数選択も出来る。

$ zip -P password sample.zip sample*
updating: sample (deflated 43%)
updating: sample.log (deflated 90%)

■分けても良い。

$ for list in sample*;do zip -P password "${list}.zip" "${list}";done
updating: sample (deflated 43%)
  adding: sample.log (deflated 90%)
  adding: sample.zip (stored 0%)

$ du *.zip
4	sample.log.zip
4	sample.zip
4	sample.zip.zip

■ディレクトリ

$ mkdir sample_dir && mv sample*.zip sample_dir/
$ zip -r -P password sample.zip sample_dir
  adding: sample_dir/ (stored 0%)
  adding: sample_dir/sample.zip.zip (stored 0%)
  adding: sample_dir/sample.zip (stored 0%)
  adding: sample_dir/sample.log.zip (stored 0%)

$ zipinfo sample.zip 
Archive:  sample.zip
