ds.home=/opt/abc
mykey=/opt/xyz

I use another script test.sh

我使用另一个脚本test.sh。

cd /opt
chmod 777 tempds.properties

#awk -F= -vOFS="=" 'gsub(/\./,"_",$1)+1' tempds.properties
cat tempds.properties| sed 's/\./_/g' > .tempds.properties

输出:

root@onebox:/opt# sudo ./test.sh

./test.sh: 2: /opt/tempds.properties: ds.home=/opt/abc: not found

/opt/xyz
Process finishd

2 个解决方案

#1

You create .tempds.properties from tempds.properties but then you still invoke tempds.properties.

您创建.tempds。从tempds属性。属性，但仍然调用tempds.properties。

You may skip creating the temporary file altogether:

您可以跳过创建临时文件:

eval `sed 's/\./_/g' tempds.properties`

#2

You can replace dots by tr command,

你可以用tr命令替换圆点，

tr '.' '_' .tempds.properties
