Bash - How to add new line when appending text to a file?

rated 0 times [ 1] [ 0] / answers: 1 / hits: 1286 / 2 Years ago, fri, october 28, 2022, 1:09:39

I'm running this command to append output text data to a markdown file:

git log -1 --oneline --skip=1 | tee -a page1.md

For the most part functionality is great, but I need to format the output so its readable. Right now, the command above is appending the markdown file like so:

Append1 Append2 Append3

I need it to be formatted as such:

Append1

Append2

Append3

With each time the command being run, a new line is created and populated with the git log information.

thank you for any guidance on the matter.

The Hannu's answer looks correct, but if you want to perform it as single line command - one of the possible ways is to use the cat command and process substitution like this:

cat <(git log -1 --oneline --skip=1) <(echo) | tee -a page1.md

It looks like you are using this frequently so you can add the following function at the bottom of your ~/.bashrc file:

function git-log-1 () { cat <(git log -1 --oneline --skip=1) <(echo) | tee -a "$1"

Then do source ~/.bashrc or open a new terminal and use the function as shell command:

git-log-1 page1.md
