Extracting tar.gz files in Linux, command line:
tar zxvf file.tar.gz
- z : filter the archive through gzip [ 1 ]
- x : extract files from an archive
- v : list the files processed
- f : use archive file
The command extracts the contents of a compressed archive to the current directory.
Tar creates an archive of one or several files. Then gzip is used to compress it. Or both processes are made at once by tar only, with corresponding options employed. The duality of nature - archived and compressed after - is reflected in the extension of the file ("tar.gz") and requires two procedures to be performed while extracting: decompressing and unpacking. Hence both z (decompress it) and x (unpack it) in the command.

A : Installing Arachne web browser on a disk created in RAM - Arachne runs the fastest this way. RAM size should allow for a RAM disk of 6 MB or more. In order to install and set up Arachne web browser for dial-up internet connection, there have to be several programs at hand: 1. Arachne web browser [ Download ] 2. If Arachne web browser is to be used for surfing web pages with character encoding other than Latin for West European languages, visit www.glennmcc.org/apm/ to find available character set packages and download the necessary one. 3. Mouse driver, mouse.com for instance [ Download ] 4. Archivers. For example, PKZIP [ Download ] and PKUNZIP [ Download ] 5. If it is not MS-DOS 6.0+ to be used, QEMM97 [ Download ] 6. If it is not MS-DOS 6.0+ to be used, TDSK [ Download ] Installing and setting up Arachne web browser, step by step: 1. Create a RAM disk. Which drive letter will be assigned to it comes from the assumption that A: and B: go to floppy drives (even if there is only one, both letters will be reserved anyway), C: goes to the first active primary MS-DOS partition on the first physical hard disk. If there are more disks, then there will be as many letters used consecutively as to name them all. Unless there are no devices installed using DRIVER.SYS or similar drivers, the next drive letter will be assigned to the RAM disk. In order to be sure, after having the relevant string for making RAM disk added to CONFIG.SYS (See below), computer could be restarted and what letter is assigned to the RAM disk checked by experiment. In this case, it is E: Depending on RAM size it needs to be decided how many megabytes can be reserved for RAM disk. Basically, the more the better. Since, for instance, web browser cache is going to swell during prolonged and intensive use within a session. In this example the RAM disk is 12 000 KB. The maximum size for RAMDRIVE.SYS MS-DOS driver is 32 767 KB, the one of TDSK - 64 MB. In order to create such a disk, the string has to be added somewhere in the middle of CONFIG.SYS as follows: DEVICE=C:\DOS\RAMDRIVE.SYS 12000 512 512 /E 2. Create a folder, for example C:\DRIVERS\. Put there a mouse driver, for instance mouse.com 3. Add a string starting mouse driver to AUTOEXEC.BAT. Specify there the full path to the driver, may be any: LH C:\DRIVERS\MOUSE.COM 4. Run MemMaker or OPTIMIZE from QEMM97 to optimize base memory management. If it is MemMaker, press Enter at any suggestion - MemMaker will handle it itself. Computer is going to restart several times, each time MemMaker will be re-running - again nothing, just Enter, is a safe choice. If it is QEMM97 (specifically OPTIMIZE), then there is going to be several restarts too and each time just pressing Enter is OK. 5. Start installation of Arachne web browser on RAM disk. In the case discussed it is E: A195GPL.EXE Press Y to continue: Press N to specify the path to the folder Arachne web browser is to be installed in: Specify the path to the folder Arachne web browser is to be installed in. In the case discussed it is E:\ARACHNE\.
