Users can be registered for free. JDK 5.0 is installed on linux systems, including kernel CPU, freebsd, solaris, and other operating systems.
I registered a user at this morning, and then ran to the Dragon Kernel Machine Installed in Debian linux to write a java hello program. The dragon Kernel Machine is a little slow, but it's okay, barely usable.
It seems that it is interesting to see the fil

Before you log on, you must first apply for a user registration name from the system administrator. No matter which computer the user logs on to itpnet, the user will access the same file system. 1.1 When a login prompt appears on the screen, you can enter your User Registration Name and press Enter.

Today, we use the uncompress command in UNIX to decompress the. Z file, uncompress *. Z [Destination path];
On Ubuntu 9.10, run the man uncompress command to go To the gzip and gunzip help pages,
You can view the help and cannot find out how to decompress the file to the specified directory,
Use the following comm
the a1.doc.tar.gz fileMethod 1:#gzip-dc/mnt/lgx/a1.doc.tar.gz (Generate A1.doc.tar file)#tar-xvf/mnt/lgx/a1.doc.tar (Generate A1.doc file)These two commands can also use the pipe function to combine two commands:#gzip-dc/mnt/lgx/a1.doc.tar.gz | Tar-xvfMethod 2: Use tar to provide automatic call to gzip decompression function#tar-xzvf/mnt/lgx/a1.doc.tar.gzAfter the tar is packaged, Compress command compression is also available (note: gzip is more efficient than compress compression), resulting

Dir
Purpose: Dir is used to list the contents of directories on some platforms.
For example, Dir (DIR has the same functions as LS, but it has fewer options. DIR is not suitable for all UNIX systems ).
Du
Purpose: Report disk usage by Du.
Example: Du. The following is the list output after the du command is executed.
Echo
Purpose: ECHO is used to display the specified text content.

Most of the time, I found that friends who asked these questions have two characteristics: 1) fear of Unix and lack of confid

Many new Linux beginners are concerned about the differences between Linux and windows. here is the difference between Linux and UNIX. figuring out some differences will help us understand the operating system. the difference between LinuxUnix is described here. the biggest difference between Linux and UNIX is that the former is free software for source code development, while the latter is concerned about
At present, Windows operating systems have occupied desktop computers, while UNIX still plays an irreplaceable role in the field of high-end workstations and servers. Especially for Internet servers, the high performance and high reliability of UNIX are not comparable to those of Windows NT computers.
However, UNIX is not a separate product of a manufacturer. In
The Unix tradition tends to delegate a task to a process, but within a task is not just a thread, like all members of a company, everyone is doing the same thing, everyone is only part of it, and when the grain size is reduced, everything can be done at the same time, anyway, Everyone also shares all the resources. So there is a thread. Threads are a different thread of shared resources. The semantics of threading are different from plain
