Add line breaks to Grep Commands
Clash Royale CLAN TAG#URR8PPP
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty margin-bottom:0;
How can I add a few line breaks? I want it to show OpenFin category, have a line break, Chrome category, another line break, then memoryInfo.
Here is what I have so far:
cat LoginExInternal.txt | grep OpenFin >> LoginExcInternal.txt | echo $'r'
&& cat LoginExInternal.txt | grep Chrome >> LoginExcInternal.txt | echo $'r'
&& cat MemoryUnderThreshold.txt | grep memoryInfo:jsHeapSizeLimit:1 >> LoginExcInternal.txt | echo $'r'
I can't seem to get it into new lines though, the echo $'r' doesn't seem to work. Please tell me how I can modify to make this work.

It would help to see (a reasonable part of) the contents of your filesLoginExInternal.txtandMemoryUnderThreshold.txtand how the result should look like. Do you user(CR) to get DOS/Windows line endings (r+norCR+LF)?

You don't need to use cat with grep, and you can group the commands to only put the redirection there once:
grep OpenFin < LoginExInternal.txt && echo
grep Chrome < LoginExInternal.txt && echo
grep memoryInfo:jsHeapSizeLimit:1 < MemoryUnderThreshold.txt && echo
>> LoginExcInternal.txt
Note also that if you join all the commands with &&, then a failing grep will stop the following echo, but also the rest of the greps from running. That may or may not be what you want. Using just grep && echo as above would have all the greps run in any case, but only print the extra newlines when the grep matches something.
Also, I'm not exactly sure how linebreaks are handled in cygwin, that is, if explicitly printing out the carriage return $'r' is required.

This did not work for me. This is a part of a bigger script, when I added it, it said the grep command was not found. I think I will use what I have as it works, thanks for trying to help!

@IbrahimA, grouping with braces shouldn't affect what commands are found or not, so if you had grep working in the original, I can't see why it wouldn't work here.
