Use the Restclient tool to test the RESTful services interface under Linux __linux

Originally always use Restclient-ui tool, is the graphical interface, the operation is very troublesome. Want to use Shell script batch call to execute use case, so find Restclient tool has no command line, the Internet search, sure enough. The download address is: Http://code.fosshub.com/WizToolsorg-RESTClient/downloads. How to call it. Search for a moment, the original to do so, if the installation of Java.

Embedded Linux Setup Path

Bloggers are now doing the development of a platform for a Realtek SDK. For some needs, add/usr/local/bin to the PATH environment variable.The embedded Linux file system does not have/etc/profile similar files, only/etc/rcs. Bo Master found in the/etc/rcs add ' path= $PATH:/usr/local/bin ' did not make it in the serial terminal to take effect.Bo Master Reasoning, why the system default PATH is: '/bin:/sbin/

Linux growth path (gcc compilers, static libraries, dynamic libraries)

executable code at compile time, and does not need to be linked again when the program loads as if it were using a dynamic library. In theory, an executable program uses a static library, which is 1%~5% faster than using a dynamic library.(1) Create a static librarySuppose you have a source code STATIC_LIB.C:int add (int a, int b) {return a + B;} int sub (int a, int b) {return a-A;} int mul (int a, int b) {return a * b;} int div (int a, int b) {return a/b;}now to compile it into a static librar

A detailed description of Linux library files

For example: We will create a static library named Myhello, then the static library file name is LIBMYHELLO.A. You need to be aware of this when creating and using static libraries. Create a static library with the AR command.At the system prompt, type the following command to create a static library file, Libmyhello

Let's start by looking at the Linux system boot-up process:Ubuntu is a Linux system derivative system, its start-up process and the difference is not small, but with the continuous development of the system, after all, there are different places, below, we come to understand the Ubuntu12.10 system self-priming process.2. The first process at Linux startup is/sbin/init, its main function is the software execution environment, including the system hostname, network settings, language processing

Time zone issues for cron execution time under Debian

:~# Date-uWed 8 16:25:28 UTC 2014root@111cn.net:~# Date-rWed 2014 16:25:37 +0000 Summary reason: Within the Linux system, the system time is determined by hardware time, UTC (/ETC/DEFAULT/RCS), timezone three factors. Where the UTC option in/etc/default/rcs tells the Linux system whether this hardware time is UTC, TimeZone is the UTC time zone where the system is set (we are usually set to Asia/shanghai).

Pattern rules in the makefile

target file, make does not look for other hidden rules for the target file, but uses the rule that appears in the makefile directly. When used, explicit rules always take precedence over implied rules. 3. In addition, the existence of dependent files, or the rules mentioned, prevail over those rules that require the use of implicit rules to create their dependent files. Pattern Rule Example This section looks at some examples of using pattern rules that have been predefined in GNU make. First
