.rar compressed file under linux

Download a rar for linux software online, its suffix is ​​tar.gz which means it is compressed in Unix file format, we can use it in the terminal (you must complete this command in super user state!) Tar -zxvf filename.tar.gz --directory=/opt(opt can also be any folder you want to install) Then we can transfer to the rar for linux installation folder to execute a make command, but in order to Easy to use, we can create two symbolic links in usr/bin [root@walter downloads]# ln -s /opt/rar/rar /usr/bin/rar [root@walter downloads]# ln -s /opt/rar /unrar /usr/bin/unrar

This is installed, there are two programs rar and unrar after installation, rar is the compression program, unrar is the decompression program. They have a lot of parameter options, here is a brief introduction, to illustrate its usage: (There may be problems with missing libraries, see below)

# rar a all *.jpg

This command compresses all .jpg files into a rar package called all.rar, which will automatically append the .rar extension to the package name. # unrar e all.rar This command is to extract all the files in all.rar.

The above method is suitable for installing rarlinux-3.6.tar.gz, but I downloaded rarlinux-3.7.1.tar.gz software, can not be installed successfully

(Runtime prompt is missing. So library file)

Online to find several ways to solve rarlinux

After decompression, you can directly make (but use this method, hint: unrar: error while loading shared libraries: libstdc++ .so.6: can not open shared object file: No such file or directory) Second, according to the above tips, echo $PATH, and then add libstdc++.so.6 to the system directory. Third, there is a rar_static file in the unpacked file. This is a static-linking version, just use this program.

cp rar_static /usr/local/bin/rar

Follow the rar a way to create a compressed file, use rar x to open the file. The third method prompts FATAL: kernel too old

It seems to be upgrading the kernel!

===================================================== ============================================================================================================ Software, using the third method, everything is OK! But using the first method still does not work, or prompts an error.

******************************************** ********************* rar command detailed

rar e arm.rar file1 file2 ... compressed file. . . To arm.rar

rar x arm.rarfull path decompression

rar x arm.rar -ap path Extract to the folder. . .

Usage: rar <command> -<option 1> ….-<option N> <action document> <file…> <@file list…> ; <Decompression path>

The usual rar command consists of a main command plus a number of options (optional). The operation document is a .rar file object applied to the operation. The file or file list is modified for the operation document. Specific file or directory (optional). -------------------------------------------------- ----------------------rar Commonly used commands mainly have a file added to the operation document Example: rar a test.rar file1.txt If the test.rar file does not exist , package the file1.txt file into test.rar Example: rar a test.rar file2.txt If the test.rar file already exists, add the file2.txt file to test.rar (so there are two in test.rar) File) Note, if there is already a copy of a file in the operation document, the a command updates the file, and the directory can also be operated. rar a test.rar dir1

c Add to the operation document Explain the comment rar c test.rar (Reading comment from stdin will appear, then enter one or more lines of comments, ending with ctrl+d) cf add file comments, similar to c above, but this is for compressing each file in the document Make comments

cw Write document comments to the file Example: rar cw test.rar comment.txt

d Delete files from the document Example: rar d test.rar file1.txt

e Extract the file to the current directory. Example: rar e test.rar Note: If you use e to extract, not only the original file1.txt and file2.t Xt is decompressed to the current directory, even all the files in dir1 are decompressed to the current directory, can not maintain the directory structure before compression, if you want to maintain the directory structure before compression, use x to extract

k lock Document example: rar k test.rar After locking the document, the document can not be updated anymore

r Repair document example: rar r test.rar When the rar file has problems, you can try to use this command Fix (Ghost know how much)

s Convert document into self-extracting document Example: rar s test.rar will generate a test.sfx executable file, the effect of running it is equivalent to rar x test. Rar, suitable for transferring files to users without rar

t Detection document example: rar t test.rarTest the integrity of test.rar, generally compress large files ready to transfer before using this command to ensure The correctness of the file

x With the path to extract the contents of the document to the current directory Example: rar x test.rar such decompression, dir1 will maintain the original directory structure

The above is the common rar Command, a rar operation can only have one command, but the option can have multiple .
