gzip压缩目录

⑴ 将/var目录打包并压缩成gzip格式,文件名为var.tar.gz,保存到/tmp目录下

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

⑵ 怎样将linux中的var目录打包并压缩成gizp格式

cd /var 先进入到/var目录,
gzip /tmp/var.tar.gz 压缩

不过因为要压缩成tar.gz文件,一般先要用tar工具打包,再用gzip工具压缩.

⑶ 为什么Linux的文件夹叫目录，而且不能用gzip压缩

文件夹就是目录，不同说法而已
命令上都是cd dir
gzip不能针对整个目录进行压缩，只能递归压缩目录下的每一个文件。
当然，替代方案是只用tar进行打包，比如
tar cfz dir.tar.gz dirname

⑷ gzip怎么压缩和怎么解压缩文件到其他目录

1. 解决：gzip -c test.txt > /root/test.gz，文件流重定向，解压也是，gunzip -c /root/test.gz > ./test.txt

2. 经验：更常用的命令tar同样可以解压*.gz，参数为-c

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).

权限不够，做这个操作必须是-user student 用户或超级用户root，其他用户都会报错。

⑹ linux 中 用gzip 如何压缩目录

linux 中用gzip 压缩目录步骤如下：

1、打开linux客户端。

⑺ 怎样在linux下对目录进行压缩生成gz文件

在linux下，使用gzip命令可以对目录压缩生成gz文件，具体步骤如下：

1、首先，连接相应专linux主机，进入到linux命令行状态下，属等待输入shell指令。

⑻ 在Linux下如何用tar命令调用gzip进行高压缩率的打包将指定目录下的所有文件及文件夹打包到指定目录下

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

⑼ redhat的gzip问题 gzip压缩多个文件和目录放到一个gz文件时总提示没有如此文件和目录。每都变成了.gz了

tar可以直接这样做，gzip可以配合tar来做！希望能帮到你，你可以自己搭建一个虚拟机做做实验！

⑽ Linux命令gzip -d怎么解压到指定路径

gzip 本身并没有解压到指定目录的参数。

如果是单文件压缩，可以用-c加输出重定向实现指定解压目录，如：

echohello>xxxx#创建一个文件
mkdirdir1#创建一个测试目录
gzip-cxxxx>./dir1/xxxx.gz
rmxxxx
cddir1
gzip-cdxxxx.gz>../xxxx
ls-lxxxx

如果是用tar命令打包的文件压缩包，可以直接用tar命令-C功能指定目录，如：

tarcvfxxx.tarxxxx#文件打包
gzipxxx.tar#压缩
tarzxvfxxx.tar.gz-C./dir1#解压到指定目录
ls-l./dir1/xxxx#查看结果
