Have you ever seen a train on the Linux command line? What about the cat and the mouse? Editing the Linux command line is not always a serious matter. You can totally entertain yourself with it. Let's talk about the nature of the Linux command

modifications to its behavior by reading standard input or file name parameters and writing to standard output and standard errors. Not long ago I developed selpg for a customer. Then I published it on a UNIX mail list, and many members told me they found it a useful tool. The utility reads text input from a standard input or from a file name given as a command line parameter. It allows you to specify the

a useful tool. The utility reads text input from a standard input or from a file name given as a command line parameter. It allows you to specify the page range from the input and will be output later. For example, if the input contains 100 pages, you can specify to print only 35th to 65 pages. This feature is of practical value because printing selected pages on a printer avoids wasting paper. Another exa

. Standardized optionsThere are some letter options that have the standard meaning. It's best to define option meaning by standard meaning-a–c–d–e–f–h–i–l–n–o–q–r–s–v-x–y 6. Get user inputWhen you need to obtain input from the execution script during execution, use the Read command1) Basic ReadingThe read command accepts standard input or other file descriptor input. After reading, put the data into a standard variable.-P allows you to specify a prom

variable calls in double quotation marks unless you have enough reasons for not doing so. Similarly, if you use a variable name directly after a letter or number, make sure that the variable name is included in square brackets, to separate it from the surrounding region. Otherwise, Shell interprets the trailing text as part of the variable name -- and may return a null value. Listing 8 provides examples of variables for reference and non-reference an

analyzer Tcpdump is one of the most widely used network packet analyzer or package monitoring programs. It is used to capture or filter TCP/IP packets received or transmitted on a specified interface on the network. It also has an option to save the captured package to the file for later analysis. Tcpdump can be used in almost all major Linux releases. # Tcpdump-I eth0tcpdump: verbose output suppressed, use-v or-vv for full protocol decode Listening on eth0, link-type EN10MB (Ethernet), capt

After all, there are not many companies that can be "agile" to TW. Compared with the above, it is more than enough. Naturally, I have some experience.
