I think on macos, perl is a better choice (for this REGEX):

Code:
macos$ perl -p -e 's/name:/\nname:/g' test.txt > a.txt

Code:
macos$ cat test.txt a.txt
name:Pages, path:/Applications/Pages.app, class:login item, kind:Application, hidden:false, name:Calculator, path:/System/Applications/Calculator.app, class:login item, kind:Application, hidden:true, name:Calendar, path:/System/Applications/Calendar.app, class:login item, kind:Application, hidden:false

name:Pages, path:/Applications/Pages.app, class:login item, kind:Application, hidden:false, 
name:Calculator, path:/System/Applications/Calculator.app, class:login item, kind:Application, hidden:true, 
name:Calendar, path:/System/Applications/Calendar.app, class:login item, kind:Application, hidden:false

Also, FYI.. on macOS, you can also install GNU sed and it works as expected:

brew install gnu-sed

Code:
macos$ gsed  's/name:/\nname:/g' test.txt > a.txt
macos$ cat test.txt a.txt
name:Pages, path:/Applications/Pages.app, class:login item, kind:Application, hidden:false, name:Calculator, path:/System/Applications/Calculator.app, class:login item, kind:Application, hidden:true, name:Calendar, path:/System/Applications/Calendar.app, class:login item, kind:Application, hidden:false

name:Pages, path:/Applications/Pages.app, class:login item, kind:Application, hidden:false, 
name:Calculator, path:/System/Applications/Calculator.app, class:login item, kind:Application, hidden:true, 
name:Calendar, path:/System/Applications/Calendar.app, class:login item, kind:Application, hidden:false

Hi @Neo,


Thank you very much. Yes, perl did the job. I will find something with sed or awk and avoiding installing gsed.


Code:
tests-Mac:~ test$ osascript -e 'tell application "System Events" to get properties of every login item'| perl -p -e 's/, name:/\nname:/g'
name:Dictionary, path:/Applications/Dictionary.app, class:login item, kind:Application, hidden:false
name:CCleaner, path:/Applications/CCleaner.app, class:login item, kind:Application, hidden:false
name:Calendar, path:/Applications/Calendar.app, class:login item, kind:Application, hidden:false
name:Dashboard, path:/Applications/Dashboard.app, class:login item, kind:Application, hidden:false
tests-Mac:~ test$

Thank you very much.

Welcome.

I think you will have some trouble with sed on the mac. I checked the web, and this newline issue on the macos version of sed is very frustrating for many people . The best idea for sed (on macos) is to install gsed.

However, perl works well, as you discovered.

I'm sure one of our many very talented and world exceptional awk experts has a great awk idea for you. I never really enjoy using awk, my bad, and generally process text with PHP or Python, only because I prefer more self-descriptive syntax for future maintenance and code changes years later (but that's just me... YMMV).

See the post #6.
The two lines approach works with any sed and any standard shell.

That works from the shell command line for sure.

But, I don't think the original poster wants to necessarily force a line break like that into his sequence of commands, when their are clearly alternatives:

For example, using perl:

Code:
 osascript -e 'tell application "System Events" to get properties of every login item'| perl -p -e 's/, name:/\nname:/g'

so it becomes:

Code:
 osascript -e 'tell application "System Events" to get properties of every login item'| sed 's/, name/\
name/g'

It's a matter of personal preference (goes without saying) and in this case, what is the preference of the original poster, 7adi, on macOS?

I know what my personal preference is (sed on Linux, gsed or perl on macOS ). But for the original poster, I have no idea what is their preference.
