gzip壓縮目錄

⑴ 將/var目錄打包並壓縮成gzip格式,文件名為var.tar.gz,保存到/tmp目錄下

tar -zcvf /tmp/var.tar.gz /var

⑵ 怎樣將linux中的var目錄打包並壓縮成gizp格式

cd /var 先進入到/var目錄,
gzip /tmp/var.tar.gz 壓縮

不過因為要壓縮成tar.gz文件,一般先要用tar工具打包,再用gzip工具壓縮.

⑶ 為什麼Linux的文件夾叫目錄，而且不能用gzip壓縮

文件夾就是目錄，不同說法而已
命令上都是cd dir
gzip不能針對整個目錄進行壓縮，只能遞歸壓縮目錄下的每一個文件。
當然，替代方案是只用tar進行打包，比如
tar cfz dir.tar.gz dirname

⑷ gzip怎麼壓縮和怎麼解壓縮文件到其他目錄

1. 解決：gzip -c test.txt > /root/test.gz，文件流重定向，解壓也是，gunzip -c /root/test.gz > ./test.txt

2. 經驗：更常用的命令tar同樣可以解壓*.gz，參數為-c

3. 附gzip幫助文件

GZIP(1) General Commands Manual GZIP(1)

NAME

gzip, gunzip, zcat - compress or expand files

SYNOPSIS

gzip [ -acdfhlLnNrtvV19 ] [-S suffix] [ name ... ]

gunzip [ -acfhlLnNrtvV ] [-S suffix] [ name ... ]

zcat [ -fhLV ] [ name ... ]

OPTIONS

-a --ascii

Ascii text mode: convert end-of-lines using local conventions.

This option is supported only on some non-Unix systems. For

MSDOS, CR LF is converted to LF when compressing, and LF is con‐

verted to CR LF when decompressing.

-c --stdout --to-stdout

Write output on standard output; keep original files unchanged.

If there are several input files, the output consists of a

sequence of independently compressed members. To obtain better

compression, concatenate all input files before compressing

them.

-d --decompress --uncompress

Decompress.

-f --force

Force compression or decompression even if the file has multiple

links or the corresponding file already exists, or if the com‐

pressed data is read from or written to a terminal. If the input

data is not in a format recognized by gzip, and if the option

--stdout is also given, the input data without change to

the standard output: let zcat behave as cat. If -f is not

given, and when not running in the background, gzip prompts to

verify whether an existing file should be overwritten.

-h --help

Display a help screen and quit.

-l --list

For each compressed file, list the following fields:

compressed size: size of the compressed file

uncompressed size: size of the uncompressed file

ratio: compression ratio (0.0% if unknown)

uncompressed_name: name of the uncompressed file

The uncompressed size is given as -1 for files not in gzip for‐

mat, such as compressed .Z files. To get the uncompressed size

for such a file, you can use:

zcat file.Z | wc -c

In combination with the --verbose option, the following fields

are also displayed:

method: compression method

crc: the 32-bit CRC of the uncompressed data

date & time: time stamp for the uncompressed file

The compression methods currently supported are deflate, com‐

press, lzh (SCO compress -H) and pack. The crc is given as

ffffffff for a file not in gzip format.

With --name, the uncompressed name, date and time are those

stored within the compress file if present.

With --verbose, the size totals and compression ratio for all

files is also displayed, unless some sizes are unknown. With

--quiet, the title and totals lines are not displayed.

-L --license

Display the gzip license and quit.

-n --no-name

When compressing, do not save the original file name and time

stamp by default. (The original name is always saved if the name

had to be truncated.) When decompressing, do not restore the

original file name if present (remove only the gzip suffix from

the compressed file name) and do not restore the original time

stamp if present ( it from the compressed file). This option

is the default when decompressing.

-N --name

When compressing, always save the original file name and time

stamp; this is the default. When decompressing, restore the

original file name and time stamp if present. This option is

useful on systems which have a limit on file name length or when

the time stamp has been lost after a file transfer.

-q --quiet

Suppress all warnings.

-r --recursive

Travel the directory structure recursively. If any of the file

names specified on the command line are directories, gzip will

descend into the directory and compress all the files it finds

there (or decompress them in the case of gunzip ).

-S .suf --suffix .suf

When compressing, use suffix .suf instead of .gz. Any non-empty

suffix can be given, but suffixes other than .z and .gz should

be avoided to avoid confusion when files are transferred to

other systems.

When decompressing, add .suf to the beginning of the list of

suffixes to try, when deriving an output file name from an input

file name.

pack(1).

-t --test

Test. Check the compressed file integrity.

-v --verbose

Verbose. Display the name and percentage rection for each file

compressed or decompressed.

-V --version

Version. Display the version number and compilation options then

quit.

-# --fast --best

Regulate the speed of compression using the specified digit #,

where -1 or --fast indicates the fastest compression method

(less compression) and -9 or --best indicates the slowest com‐

pression method (best compression). The default compression

level is -6 (that is, biased towards high compression at expense

of speed).

⑸ linux文將於目錄的壓縮和解壓縮命令：gzip壓縮文件

許可權不夠，做這個操作必須是-user student 用戶或超級用戶root，其他用戶都會報錯。

⑹ linux 中 用gzip 如何壓縮目錄

linux 中用gzip 壓縮目錄步驟如下：

1、打開linux客戶端。

⑺ 怎樣在linux下對目錄進行壓縮生成gz文件

在linux下，使用gzip命令可以對目錄壓縮生成gz文件，具體步驟如下：

1、首先，連接相應專linux主機，進入到linux命令行狀態下，屬等待輸入shell指令。

⑻ 在Linux下如何用tar命令調用gzip進行高壓縮率的打包將指定目錄下的所有文件及文件夾打包到指定目錄下

GZIP="-9" tar zcvf /home/homee.tgz /media

⑼ redhat的gzip問題 gzip壓縮多個文件和目錄放到一個gz文件時總提示沒有如此文件和目錄。每都變成了.gz了

tar可以直接這樣做，gzip可以配合tar來做！希望能幫到你，你可以自己搭建一個虛擬機做做實驗！

⑽ Linux命令gzip -d怎麼解壓到指定路徑

gzip 本身並沒有解壓到指定目錄的參數。

如果是單文件壓縮，可以用-c加輸出重定向實現指定解壓目錄，如：

echohello>xxxx#創建一個文件
mkdirdir1#創建一個測試目錄
gzip-cxxxx>./dir1/xxxx.gz
rmxxxx
cddir1
gzip-cdxxxx.gz>../xxxx
ls-lxxxx

如果是用tar命令打包的文件壓縮包，可以直接用tar命令-C功能指定目錄，如：

tarcvfxxx.tarxxxx#文件打包
gzipxxx.tar#壓縮
tarzxvfxxx.tar.gz-C./dir1#解壓到指定目錄
ls-l./dir1/xxxx#查看結果
