Explanation:In this scenario, the for loop iterates over the elements and verifies whether each element’s value is equal to 4. If the condition satisfies, the program will skip the subsequent commands following the “continue” statement and proceed to the next item in the iteration. In the ...
For example, if you’re sending data from Host A to Host B, as shown in Figure 9-1, your bytes leave the application layer on Host A and travel through the transport and network layers on Host A; then they go down to the physical medium, across the medium, and up again through the...
In addition to the applet, there are a few tools that you can use to query and control NetworkManager from your shell. For a very quick summary of your current connection status, use the nm-tool command with no arguments. You’ll get a list of interfaces and configuration parameters. In ...

forLoops An alternative loop structure is theforloop. It is also used to run a block of code repeatedly under a condition, but it has more options than awhileloop. In the loop control condition, you can add the temporary variable, define the control condition, and change the value of the...
As with any program on Unix systems, you need to set the executable bit for a shell script file, but you must also set the read bit in order for the shell to read the file. The easiest way to do this is as follows: 与Unix 系统上的任何程序一样,您需要为 shell 脚本文件设置可执行位...
