巴什一套+ X未经打印它 [英] Bash set +x without it being printed

问题描述

有谁知道，如果我们可以说设置+ X 在没有它进行打印庆典：

Does anyone know if we can say set +x in bash without it being printed:

set -x
command
set +x

痕迹

+ command
+ set +x

但它应该只是打印

but it should just print

+ command

击是4.1.10版（4）。这是窃听我有一段时间了 - 输出堆满了没用设置+ X 线，使得跟踪工具，因为它可以不是有用

Bash is Version 4.1.10(4). This is bugging me for some time now - output is cluttered with useless set +x lines, making the trace facility not as useful as it could be.

推荐答案

我有同样的问题，我能找到不使用子shell的解决方案：

I had the same problem, and I was able to find a solution that doesn't use a subshell:

set -x
command
{ set +x; } 2>/dev/null
