There are many Linux compression and packaging methods. The following describes the concepts of gzip and zcat commands, and lists examples of various Linux compression and packaging methods for your reference, hope to help you ....

The previous article introduced the tar command of the Linux compression and decompression command. I believe that, for example, you should be familiar with the application of the tar command. Here we will continue to introduce the two Linux compression and decompression commands gzip, the zcat and bzip2 and bzcat commands are as detailed as above. Gzip and zcat commands [Root @ linux ~] # Gzip [-cdt #] Fil

There are many compression tools in Linux, this article mainly introduces Gzip/gunzip/zcat, Bzip2/bunzip2/bzcat, tar, Zip/unzip. For ease of presentation. We first set up a text file called "Test.txt", which reads as follows: Hello! This is a test! End of file. 1. Gzip/gunzip/zcat Gzip is used to compress common files; Gunzip is used to extract the compressed files that are created by gzip; Gcat is used t

To reduce the amount of space occupied by log files, in many cases we package the log files in days or weeks as tar.gz packages. While this is a good space to take advantage of, it is inconvenient when we want to look at the contents of a compressed package. If it's just a tar.gz file, unzip it, and then use grep, awk, or VI tools to view or process it. However, if there are one months or a year of log need to find some key words of the line, one of the decompression, and then look, is not very

For example, I want to back up the/etc and/root directories, but I don't want to package the files with the install switch, and I don't want to package the files

each other. Therefore, when downloading a compressed file, you need to know which compression command is used to decompress the file. Although the attributes of a Linux file are basically irrelevant to the file name, the proper extension is necessary to help us identify the file. The following extensions are commonly used compressed files in Linux: *. Z files compressed by the compress program; // This compression command is not supported by default in mainstream Linux versions, because the gzi
