When I was reading the code today, I met the getopt_long function and checked the relevant information. It is the parameter parsing of the command line. I will take some notes today. In Linux, many programs, even those with graphical user interfaces (guis), can accept and process command line options. For some programs

In the QT program, some directories and files need to be compressed into a RAR archive. Then thought of in Qt through the Qprocess Class call command line Rar.exe to achieve the effect, but did not think Qprocess class used to be very troublesome, and can not reach the effect, tossing for 2 days still did not find the reason, using another method to solve.How to create a compressed packageTo create a compre

PHP is an open source server-side scripting language, originally three letters representing the "Personal Home page", and now stands for "Php:hypertext preprocessor", which is a recursive acronym. It is a cross-platform scripting language that is heavily influenced by C, C + +, and Java.Running PHP code on the Linux command linePHP's syntax is very similar to the syntax of C, Java, and Perl with some PHP features, which is currently used by 260 millio

Docopt is a tool used to parse command line parameters. if you want to append parameters to the Python program, you don't need to worry about it. The following article mainly introduces docopt, a command line parameter parsing tool in Python. the introduction is very detailed. let's take a look at it. Docopt is a tool

relationships between processes is really a very effective tool (poke here).PmapDuring debugging, it is important to understand how an application uses memory, and the PMAP is to display relevant information when a process ID is given. The above shows some of the output produced using the '-X ' option, and you can use the Pmap '-X ' option to get more details, but only if you have a wider terminal window.IostatOne of the most important performance metrics for Linux systems is processor and stor

| head-5 ', $data); Print_r ($data); #would print out the data array: #Array ([0]=> 555 text1.txt [1] = 283 text2.txt) ?> After capturing the results in the array, you can do some processing on each row. For example, you can partition the first space, store the detached values in a database table, or apply a specific format or tag to each row. System () As shown in Listing 10, the system () command is a hybrid. It directly outputs anything received

Remember, in double quotes , parameter expansion, arithmetic expression expansion, and command substitution are still valid: [[[Emailprotected] ~]$ echo "$USER $ (()) $ (CAL)" Me 4 February 2008Su Mo Tu We Th Fr sa below Examples are unreferenced, double quotes, and single quote comparison results: [[emailprotected] ~]$ echo text ~/*.txt {A, B} $ (echo foo) $ ((+)) $USERtext/home/me/ Ls-output.txt a B foo

This article explains what the process of a Linux command is going through when it executes. And the approximate sequence of these processes.1.1 Shell parsing command lineThe approximate operation of the shell when reading and executing commands is as follows:Take the following command as an example:Echo " Some files: " " \nthe date:$ (date +%f) \n$name ' s is $

process.COMMAND: COMMAND Line for starting a task (including parameters)Process Priority and nice levelThe process priority is a parameter that determines the priority of processes executed by the CPU. The kernel will adjust this value as needed. Nice value is a restriction on priority. The process priority value cannot be lower than the nice value. (The lower the nice value, the higher the priority)The pr

see that the interface concepts are different for different users. So when it comes to the user interface, don't just think about the GUI at once. The first thing is to see who the user is in this environment. We usually talk about the user interface for end users. In fact, you still have other interfaces, such as the interfaces provided for debugging and testing, which are not necessarily GUI interfaces. They may be command
