Synology NAS 内（SSH 接続）で，zip ファイルを扱えないかと…
検索すると，Linux 環境では zip や unzip があるらしい．
SSH で接続して確認すると，zip はあるが unzip は command not found ．
さらに検索すると Synology Forum に情報があった．
Unzip?
7z コマンドが利用できるみたい．
Iwao@DS116:~$ zip
Copyright (c) 1990-2008 Info-ZIP - Type 'zip "-L"' for software license.
Zip 3.0 (July 5th 2008). Usage:
zip [-options] [-b path] [-t mmddyyyy] [-n suffixes] [zipfile list] [-xi list]
The default action is to add or replace zipfile entries from list, which
can include the special name - to compress standard input.
If zipfile and list are omitted, zip compresses stdin to stdout.
-f freshen: only changed files -u update: only changed or new files
-d delete entries in zipfile -m move into zipfile (delete OS files)
-r recurse into directories -j junk (don't record) directory names
-0 store only -l convert LF to CR LF (-ll CR LF to LF)
-1 compress faster -9 compress better
-q quiet operation -v verbose operation/print version info
-c add one-line comments -z add zipfile comment
-@ read names from stdin -o make zipfile as old as latest entry
-x exclude the following names -i include only the following names
-F fix zipfile (-FF try harder) -D do not add directory entries
-A adjust self-extracting exe -J junk zipfile prefix (unzipsfx)
-T test zipfile integrity -X eXclude eXtra file attributes
-y store symbolic links as the link instead of the referenced file
-e encrypt -n don't compress these suffixes
-h2 show more help
-yf store files/directories that symbolic links point to in an archive
-cp codepage, ex: fre,ger,ita,spn,cht,chs,jpn,krn,ptb,rus,dan,nor,sve,nld,plk,ptg,hun,trk,csy
