After some processing, I have my input file like below.
file1.txt
12345|john|student
43321|jack|professor
78965|alex|lecturer
I need to process the above file further and so I need a line breaker at the end of the line too. Currently, I can accomplish it as below.
sed 's/$/|/' file1.txt
The above command results in the output as,
12345|john|student|
43321|jack|professor|
|
78965|alex|lecturer|
As we can see, the |
is appended to blank lines too. When I tried to remove the |
character again from blank lines using below command,
sed 's/|//g' file1.txt
The |
character is getting deleted everywhere. How can I delete only the |
in blank lines? I need to keep the blank line also.
