Hello All,
I am a newbie and have been struggling to print in loop.
I have one line hold in a variable and need to print them with first six strings.
We have get the value with below macOS terminal command.
osascript -e 'tell application "System Events" to get properties of every login item'
need to print them with new line like below:
I know i did wrong but i use simple logic to print them with below.
Did you try something simple like?
sed 's/, name/\nname/g' yourfile.txt
ubuntu$ sed 's/, name/\nname/g' yourfile.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
ubuntu$ cat yourfile.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
Thank you @Neo for your quick response. But that didn't work as expected.
I tried with two ways with your advise:
Is it due to the variable holds as one word?
Deleted post because my comment was accidentally on the output and not the input.
See my post below specific to macos and using perl instead of sed or using gsed on macos .
Earlier sed code works on linux but not macos .
Apologies. I tried again. I am confused here. I did exactly same as you advised. They printed in other way as highlighted below.
The strings changed to smiley when I paste it from my terminal and had to edit. The code still remain same as in my initial post.
user$ cat yourfile.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
user$ sed 's/, name/\nname/g' yourfile.txt
name:Pages, path:/Applications/Pages.app, class:login item, kind:Application, hidden:falsenname:Calculator, path:/System/Applications/Calculator.app, class:login item, kind:Application, hidden:truenname:Calendar, path:/System/Applications/Calendar.app, class:login item, kind:Application, hidden:false
What's your shell and sed versions? Either of them may not like the \n notation and interprets it as a plain n... as you can see in falsenname Try a verbatim new line char:
sed 's/, name/\
name/g' file
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,
@rudic, you might be correct something must be with shell version. Below is the output that might help to provide additional advice. I was not able to find sed version on my macOS 10.13.6 neither verbatim new line
@neo, may be we are not on same page, the code you have quoted is my output actually.

Yes, I see that now.... sorry busy working on apache2 error.... missed that (your output versus input)... my bad.
Will test something on my mac and post back.
I think on macos , perl is a better choice (for this REGEX):
macos$ perl -p -e '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
Also, FYI.. on macOS, you can also install GNU sed and it works as expected:
brew install gnu-sed
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.
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:
osascript -e 'tell application "System Events" to get properties of every login item'| perl -p -e 's/, name:/\nname:/g'
so it becomes:
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.
Hi @MadeInGermany,
Thank you.
My preference is awk as my whole (learning) script is based on it.
Since I find perl is doing better job and clean as well, I would start digging it and learn more.
Yes, your two options worked well.

Hi All,
I found how to break line with sed in macOS bash.
This doesn't require to change line.
osascript -e 'tell application "System Events" to get properties of every login item'| sed 's/, name:/\'$'\nname/g'
Good for you and happy learning!
BTW, I tried that solution you just posted and had trouble when testing; but I was in a rush coding other projects so I guess I missed it somehow, maybe misplaced the single quotes and dollar sign!
Good for you! Well done!!
How about this awk approach?
awk '{gsub (/, name/, ORS "name")} 1' file
This does not work as you need. You forgot to add the colon (
back in the REGEX:
sed 's/, name:/\'$'\nname:/g'
So,
macos$ sed 's/, name:/\'$'\nname:/g' test.txt > a.txt
macos$ cat test.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
macos$ cat 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
