Usage: gzip [OPTION]... [FILE]...
Compress or uncompress FILEs (by default, compress FILES in-place).
Mandatory arguments to long options are mandatory for short options too.
-c, --stdout write on standard output, keep original files unchanged
-d, --decompress decompress
-f, --force force overwrite of output file and compress links
-h, --help give this help
-l, --list list compressed file contents
-L, --license display software license
-n, --no-name do not save or restore the original name and time stamp
-N, --name save or restore the original name and time stamp
-q, --quiet suppress all warnings
-r, --recursive operate recursively on directories
-S, --suffix=SUF use suffix SUF on compressed files
-t, --test test compressed file integrity
-v, --verbose verbose mode
-V, --version display version number
-1, --fast compress faster
-9, --best compress better
--rsyncable Make rsync-friendly archive
With no FILE, or when FILE is -, read standard input.
gunzip -h

指令參數解釋:
gzip -h
gunzip -h
不知道鬧哪樣,兩個指令的幫助文件是一樣的,開發者偷懶了
也就是說
-c
不壓縮文件,而是直接輸出到標準輸出。gunzip -
,不是從文件接收壓縮文件,而是從標準輸入接收。|
:管道>
:重定向整條命令分析
gzip -c aa.txt
:壓縮aa.txt文件,並將壓縮後的結果輸出到標準輸出ssh root@192.168.1.1 "命令":
在遠端機器上執行指令指令
gunzip -c -
:解壓縮文件,原壓縮文件是由標準輸入傳入的,輸出結果直接輸出到標準輸出> /home/bb.txt
:将标准输出重定向到文件/home/bb.txt
對資料夾進行這樣的操作會失敗
gzip不支援對目錄操作
你要嘛完全換用netcat來收發。
要么,本地tar壓縮一下,對端解壓縮。
管道是將前一個指令輸出作為輸入。 也可以先壓縮成一個臨時文件,再用scp
