How to insert a new line between two specific characters

You can run

sed -i -e 's /} {/} \ n {/ g' filename.ext

Where

• sed
  
  - your thread editor program
• -i
  
  there is an option to edit the file filename.ext
  
  in place
• -e
  
  means the regex follows
• s/}{/}\n{/g
  
  is a regular expression meaning to find all ( g
  
  ) instances of } { in each line and replace them with } \ n { , where \n
  
  is a regular expression for a new line. If you omit it g
  
  , it only replaces the first occurrence of the search pattern, but still on every line.

To check before making changes to your file, omit the parameter -i

and it will print the result to STDOUT.

Example:

Create file:

echo "First }{ Last" > repltest.txt

      

        
        
        
      

    

Run

sed -e 's/}{/}\n{/g' repltest.txt

      

        
        
        
      

    

Outputs the following data to STDOUT:

First }
{ Last

      

        
        
        
      

    

To make a change in the same file, use the option -i

.

To run this instead of STDIN instead of file, omit -i

and the filename on the command line after whatever STDIN outputs, e.g .:

cat repltest.txt | sed -e 's/}{/}\n{/g'

      

        
        
        
      

    

which does the same as sed -e 's/}{/}\n{/g' repltest.txt
