Question

I have a line with spaces in the start for example " Hello world". I want to insert this line to a specific line in a file. for example insert " hello world" to the next file

hello world 

result:

hello     hello world world 

I am using this sed script:

sed -i "${line} i ${text}" $file 

the problem is that i am getting my new line with out the spaces:

hello hello world world 

Answer 1

You can escape the space character, for example to add 2 spaces:

sed -i "${line} i \ \ ${text}" $file 

Or you can do it in the definition of your text variable:

text="\ \ hello world"
