GNU并行完全不起作用 [英] GNU parallel not working at all

问题描述

一段时间以来，我一直在尝试使用GNU并行，但是我从来没有能够使其完全正常运行！

I have been trying to use GNU parallel for some time, but I have never been able to get it to function at all!

例如，运行(在非空目录中！):

For example, running (in a non-empty directory!):

ls | parallel echo            # Outputs single new line
ls | parallel echo echo echo  # Outputs three new lines.
ls | parallel echo {}         # /bin/bash: {}: command not found
ls | parallel echo '{}'       # /bin/bash: {}: command not found
ls | parallel 'echo {}'       # Outputs: {}
ls | parallel -IMM 'echo MM'  # Outputs: MM

似乎只是将每个参数作为命令执行，这没有任何意义.

It seems that it is simply executing each argument as a command, which makes no sense.

我尝试了bash，zsh，tcsh，csh和sh，但无济于事.

I have tried bash, zsh, tcsh, csh, and sh, to no avail.

推荐答案

当我即将完成此问题的撰写时，我运行parallel --version报告该版本，却发现:

As I was about to complete writing this question, I ran parallel --version to report the version, only to find:

警告:您正在使用--toolf.如果正在使用，请使用--gnu.

WARNING: YOU ARE USING --tollef. IF THINGS ARE ACTING WEIRD USE --gnu.

我不清楚为什么默认情况下会设置该标志.不用说，使用--gnu可行！

It is not clear to me why that flag is set by default. Needless to say, using --gnu worked!

我认为发布此邮件可以节省一些人的挫败感和困惑.

Thought I would post this to save someone hours of frustration and confusion.

要永久解决此问题(至少在Ubuntu中)，请删除/etc/parallel/config

To fix this permanently (in Ubuntu at least), delete the --tollef flag in /etc/parallel/config
