标题: 给力的linux命令--parallel安装
GNU parallel是并行执行任务的shell工具。在文章情景linux—shell如何实现多线程？中提到了它的一种用法，但这远远不够，它还有许多更强大的应用场景。但在此之前，需要先安装它。

测试安装后的效果
- whereis parallel
- parallel: /usr/local/bin/parallel
- $ parallel --help
- Usage:
- parallel [options] [command [arguments]] < list_of_arguments
- parallel [options] [command [arguments]] (::: arguments|:::: argfile(s))...
- cat ... | parallel --pipe [options] [command [arguments]]
- -j n Run n jobs in parallel
- -k Keep same order
- -X Multiple arguments with context replace
- --colsep regexp Split input on regexp for positional replacements
- {} {.} {/} {/.} {#} {%} {= perl code =} Replacement strings
- {3} {3.} {3/} {3/.} {=3 perl code =} Positional replacement strings
- With --plus: {} = {+/}/{/} = {.}.{+.} = {+/}/{/.}.{+.} = {..}.{+..} =
- {+/}/{/..}.{+..} = {...}.{+...} = {+/}/{/...}.{+...}
- -S sshlogin Example: foo@server.example.com
- --slf .. Use ~/.parallel/sshloginfile as the list of sshlogins
- --trc {}.bar Shorthand for --transfer --return {}.bar --cleanup
- --onall Run the given command with argument on all sshlogins
- --nonall Run the given command with no arguments on all sshlogins
- --pipe Split stdin (standard input) to multiple jobs.
- --recend str Record end separator for --pipe.
- --recstart str Record start separator for --pipe.
- See 'man parallel' for details
- Academic tradition requires you to cite works you base your article on.
- When using programs that use GNU Parallel to process data for publication
- please cite:
- O. Tange (2011): GNU Parallel - The Command-Line Power Tool,
- ;login: The USENIX Magazine, February 2011:42-47.
- This helps funding further development; AND IT WON'T COST YOU A CENT.
- If you pay 10000 EUR you should feel free to use GNU Parallel without citing.
