我正在使用chef-solo
编写Chef食谱,我需要运行包含+
的命令,但如果我使用+
字符,Chef会返回错误。
bash "testing" do
code <<-EOH
/bin/grep '^+:' /etc/shadow >>/var/info
EOH
end
方法1:将代码放入任何script.sh
文件中并将其用作:
execute " script running " do
command "sh /path/script.sh"
end
但我不想使用它。有没有其他方法可以使用特殊字符?
注意:我尝试使用反斜杠(“\”)。
更新:使用代码时出现以下错误
bash "testing" do
code "/bin/grep '^+:' /etc/shadow >>/var/info"
end
错误:
chef-solo -c solo.rb -j web.json

答案 0 :(得分:3)
这与命令中的+无关!
没有错,厨师按预期工作:
# grep '^+' /etc/shadow; echo $?
1
此命令返回状态代码1,因为找不到任何内容(man grep
强调的引用是我的):
退出状态
如果找到选定的行,退出状态为0,,如果未找到,则退出。如果发生错误,则退出状态为2.(注意:POSIX 错误处理 代码应检查'2'或更高。)
厨师告诉你的确如此:
预期进程以[0]退出,但收到'1'
阅读bash resource documentation,我们看到此描述中有returns
属性:
returns
Ruby类型:整数,数组命令的返回值。这可能是一系列被接受的 值。当返回值不匹配时引发异常。 默认值:0。
因此,如果您想接受此命令,请返回0或1:
bash "testing" do
code "/bin/grep '^+:' /etc/shadow >>/var/info"
return [0,1]
end
所以这可能无法解决您的问题,因为您没有描述您要实现的目标,我们在XY problem这里

厨师食谱是纯粹的红宝石,所以你可以写出这样的东西,没有任何问题:
bash "testing" do
code "/bin/grep '^+:' /etc/shadow >>/var/info"
end
如果你需要在命令中使用双引号,你可以用反斜杠“\”来转义它。
