The main point of this simple solution is to demonstrate that more than one command can be put on thebashcommand line. In the first case the second command isn’t run until the first command exits, the third doesn’t execute until the second exits, and so on, for as many commands as ...
如果您希望命令行重复,我强烈建议gnu parallel运行一个包含大量文件/参数的命令parallel通常被认为是xargs更现代、更强大的替代品。 parallel --eta python3 main.py {} ::: /path/*.html 要使它一次作用于100个文件,请使用-n参数: parallel -n 100 --eta python3 main.py {} ::: /path/*.html 如果参...
If everything goes well, then you collect your files in parallel because you don’t have more than ten systems. You can afford to ssh to all of them at the same time and then show the hardware details of each one. Visiting: dmaf5 lshw-dump.json100% 54KB136.9MB/s 00:00"DMAF5 (De...

如果安装了GNU Parallel,可以执行以下操作: 1 2 3 # If doCalculations is a function export-fdoCalculations seq09|parallel doCalculations{} GNU Parallel将为您提供退出代码: 0-所有作业运行无错误。 1-253-一些作业失败。退出状态提供失败作业的数量。
A shell allows execution of GNU commands, both synchronously and asynchronously. The shell waits for synchronous commands to complete before accepting more input; asynchronous commands continue to execute in parallel with the shell while it reads and executes additional commands. The redirection constructs...
Finally, the Bash shell allows executing several processes in parallel, and their communication is managed by the operating system. Contribution. We prose to compile a Datalog program automatically into Bash commands. Our method optimizes the Datalog program with relational algebra 568 T. Rebele et ...
Parallel Pacman downloads can be enabled by uncommenting the following line: #ParallelDownloads = 3 Alias If you use PacUI without the UI it is recommended to use an alias for PacUI to reduce the amount of necessary typing. Do this by adding the following line to your ~/.bashrc file ...
