[Linux 006] -- grep and regular expression, 006 grep When using the system, we have more or less search and search requirements. We must search for a keyword in the text or filter out certain lines in the text. The grep command provides us with such a function. At the same time, grep can also use regular expressions for matching. This is a powerful function and must be well mastered.1. grep initial experien

I. OverviewThere is a state in the thread time-wait, which is often a thread in the wait time and then run, the common way is sleep,wait and so on.Here we only talk about the situation of hibernation.Two. Thread hibernationThere are two APIs that we often use, one is the sleep () method in the thread class, and the other is the sleep method of the Timeunit class provided by version 5.Example: Public Static voidMain (string[] args) throws Exception {System. out. println ("I'm going to sleep using

), so that the object has some or some of the privileges.For example: The Java.util.EventListener interface that inherits from the MouseListener interface in the Java.awt.event package is defined as follows: Package Java.util; Public Interface eventlistener{} // interfaces that do not have any methods are called labeled interfaces. The markup interface is mainly used for the following two purposes: // Create a common Parent interface:// as the EventListener interface, which is a Java API extend

The W command displays a list of users who have logged in to the system and displays the instructions that the user is executing. Execute this command to know who is currently logged in to the system, and which programs they are executing. The Execute W command alone displays all users, and you can also specify the user name to display information about only one user.Let's take a look at how the W command is described in the man page: "The W command is used to show which users have logged into t

options by default, after the installation is successful as follows.　　Iii. Configuring virtual Machine Shared Folders1. Before you turn on the virtual machine, share the folder by configuring the virtual machine. By configuring shared folders, Ubuntu can access the E:\Share directory under Windows by accessing the/mnt/hgfs/share directory. Where thelast level of directory Share in/mnt/hgfs/share is the name in the configuration, Share in E:\Share is the host path configured in. 　　2. For example

to [^0-9] 5.egrep and FgrepWhen using grep, if you want to turn on an extended regular expression, you need to specify the-e option, and the EGREP command supports extended regular expressions by default. Therefore, it is recommended to use EGREP instead of GREP-E when you need to use an extended regular expression.Fgrep represents a quick match, does not support regular expressions, has no escaping concept, and matches all characters in PATTERN.6.
