Linux regular expression-selective operations and group operations Selective operationThe vertical line (|) character is part of the metacharacters Extension Set and is used to specify the Union of regular expressions. If a row matches one of the regular expressions, it matches the pattern. For example, regular expression: UNIX | LINUXMatch the line containing the string "UNIX" or string "LINUX. You can specify more options, such:UNIX | LINUX | NETBSD When egrep is used, print the rows matchin

Thank you for your delivery in the past few months.Visionmobile released a new report showing the cross-platform tools currently used by developers, cross-platform tools to be used in future plans, and cross-platform tools to be discarded. The survey results indicate that the market is not stable, and many developers prefer to find better tools.Visionmobile, a market analysis and strategy company, conducted a survey to evaluate cross-platform tools (CPT) from the developer's perspective.

Alas, I haven't done C for a long time. A little formal point is the instant link software, which is outsourced. The salary is very high and I have checked it for a long time. After I submitted my resume, I was specially notified to attend the presentation. Why did the presentation be notified? I didn't have a

tornado development platform. VxWorks appears earlier, real-timeStrong (it is said that external event requests can be responded within 1 ms), and the kernel can be very micro (it is said that the minimum can be 8 K), high reliability, so in North America, vxWorks occupies most of the embedded systemsJiangshan district. Especially in systems with high real-time requirements such as communication devices, there is almost no such thing as VxWorks. Many concepts and technologies of VxWorks are sim

When the system image is loaded, the second-stage boot loader transfers control to the kernel image, while the kernel begins to self-extract and initialize. At this stage, the second stage of boot loader checks the hardware of the system, enumerates those additional hardware devices, mounts the root device, and then loads the required k

In the ensuing months, Mr. Paulson also overheard the phone call of a Hollywood actress and later attacked military and the FBI. The FBI ended up accusing Mr. Paulson of "series of fraud and money-laundering offences", while Mr. Paulson was sentenced to 51 months in prison, paying a fine of 56,000 dollars for damaged radio stations and a three-year stop in touch with the computer. Now Mr. Paulson is a wired m

In large-scale use of WDM networks, especially channel scheduling, one wavelength may need to be converted to another wavelength, or the entire band of the transformation. The optical band converter developed by Lucent is base

For broadband wireless access network, the world has three kinds of standards, that is, IEEE Standards, ATM Forum standards and European ETSI standards. European ETSI Broadband Wireless access Network Group research, study the use of wireless access networks, concluded that the use of different needs of the data transmission rate is different. For example, TV on demand requires 1. 5mbit/s to 6mbit/s, online browsing needs 2mbit/s, access to the enterprise network needs 10mbit/s,lan interconnecti

same band. At the same time, the different leading forces lead to different development direction of technology. WLANs are led by data communications rather than by telecommunications vendors. The leaders here are traditional corporate networking companies such as Agere, Cisco, 3Com, IBM, D-link and others. Wireless LAN vendors define mobility with their own LAN experience (like portability). Therefore, they are defined differently than the definitions used by the 3G mobile infrastructure equi

solution is to design the network in order to meet the requirements of network changes and growth to plan accordingly. 1. Investment protection in the future Under normal operating conditions, the new network should not limit system upgrades during the 15 building renovation cycle. A well-designed cabling system can withstand data traffic that is 10~15 times higher than most LAN transmission rates. This will allow the use of new network technologies without altering the wiring system. 2. Gen
