Bash命令在终端中运行，但不在脚本文件中运行 [英] Bash command runs in terminal but not in script file

问题描述

我正在尝试从目录中删除一些文件和文件夹.命令(来自此处):

I'm trying to delete some files and folders from a directory. The command (from here):

rm -rf !(file_i_don't_want_to_remove|other|other_one)

在终端上运行正常，但是如果我尝试在脚本(使用vim创建的两行代码)中使用它:

Runs fine in terminal, but if I try to use it inside a script (created using vim, 2 lines):

#!/bin/bash
rm -rf !(one|two)

./file.sh:时间2:错误sinácticocerca del elemento inesperado`('

./file.sh: línea 2: error sintáctico cerca del elemento inesperado `('

翻译:

./file.sh:第2行:意外错误'('

./file.sh: line 2: syntax error near of unexpected element `('

为什么?

PS.我一直在寻找其他同名的问题，但是它们对于每个脚本来说都太具体了，似乎与我的问题不一样.

PS. I've looked for other questions with the same name but they're all too specific for each script and seem not to be the same problem than mine.

推荐答案

您需要 extglob 扩展启用后，此语法才能起作用:

You need the extglob extension enabled for this syntax to work:

#!/bin/bash
shopt -s extglob
cd /path/to/dir # See the comment below the answer
rm -rv !(one|two)

PS:请不要在脚本中使用rm -f.

PS: Do not use rm -f in a script.

PS:如果/path/to/dir来自变量，请确保该值不为空，然后将其与cd一起使用:

PS: If /path/to/dir is coming from a variable, make sure that is is not empty before using it with cd:

if [ -z "${path_to_delete}" ] ; then
    "path_to_delete is empty! Aborting"
    exit 1
fi
cd "${path_to_delete}"
rm -rv !(one|two)
