Unix Tar Example

After you have finished this chapter, you will be able to do the following: Explain the purpose of the device file explain the meaning of the main number and the number of the different character devices use Lsdev to list the main numbers of kernel drivers use LS to observe the primary and secondary numbers of a device file Use Ioscan to list device files associated with a specified device using ISSF to describe the characteristics of a device file. Assign a disk, tape, or CD device file name, determine the target number of the control card and the target address of the associated device assigned to a terminal or a Xiandai device file ...

S6-portable-utils 0.11 is a tiny general used to perform cut and grep (grep is a powerful text search tool that can use regular expressions to search for text and print matching rows.) The UNIX grep family includes grep, egrep, and Fgrep Unix tools, but the simplicity and size of the optimizations are small. It is designed to be used in embedded systems and other restricted environments, but it can also work anywhere. Other gadget sets are usually system-specific, for example, the BusyBox project is only suitable for ...

This paper introduces how to build a network database application method by MySQL of the golden combination of Web database, PHP is a server-side embedded hypertext Processing language similar to Microsoft ASP, it is a powerful tool to build dynamic website. While MySQL is a lightweight SQL database server that runs on a variety of platforms, including Windows NT and Linux, and has a GPL version, MySQL is considered the best product for building a database-driven dynamic Web site. PHP, MySQL, and Apache are Linux ...

Rsync (synchronize) is a remote data synchronization tool that allows you to quickly synchronize files between multiple hosts by LAN. You can also use rsync to synchronize different directories on your local hard disk. Rsync is a tool to replace RCP, and Rsync uses the so-called rsync algorithm for data synchronization, which transmits only two different parts of the file, rather than sending it all at a time, so it's very fast. You can refer to how to Rsync works A ...

There are three types of applications under Linux (Red Flag Linux default for tar packages and RPM packages): The tar packets are made by the UNIX system's packaged tools tar, such as example-1.2.3-1.tar.gz. RPM Package Red Hat offers a package package format, such as example-1.2.3-1.i386.rpm. DPKG Package Debain Linux provides a package packaging format, such as example ...

Overview 2.1.1 Why a Workflow Dispatching System A complete data analysis system is usually composed of a large number of task units: shell scripts, java programs, mapreduce programs, hive scripts, etc. There is a time-dependent contextual dependency between task units In order to organize such a complex execution plan well, a workflow scheduling system is needed to schedule execution; for example, we might have a requirement that a business system produce 20G raw data a day and we process it every day, Processing steps are as follows: ...

The common compressed file format under UNIX is generated by a compression tool with a high compression rate, followed by a compressed file with a. bz2 end bzip2. GZ is a compressed file in a UNIX system, the GNU version of Zip, and features like WinRAR compressed files. bz2 and. GZ are the formats for compressed files in Linux, somewhat like. zip and. rar files under Windows. &http://www.aliyun.com/zixun/aggregation/37954.h ...

MySQL has become one of the most widely used databases in the current network, especially in Web applications, which occupy the absolute advantage of small and medium applications. It all stems from its compact, safe, efficient, open licensing and multi-platform, and, more important, the perfect combination of--php with one of the three web languages. Unfortunately, a default installation of MySQL, because the root password is empty and the program vulnerabilities caused by the overflow, so that the installation of MySQL server is a frequent target. What is more serious is that the database is often destroyed after the attack, causing disaster easily ...

BZIP2 is a lossless compression software based on Burrows-wheeler transform, the compression effect is better than the traditional lz77/lz78 compression algorithm. It is provided free of charge with high quality data compression capability. BZIP2 use of advanced compression technology, can compress files to 10% to 15%, compression speed and decompression efficiency are very high! Supports most compression formats now, including Tar.gzip, and so on. GZ is the compressed file in the UNIX system, the GNU version of Zip, and the function is as compressed as WinRAR ...
