Print strings in bash in loop
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.



Code:
osascript -e 'tell application "System Events" to get properties of every login item'


Quote:
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

need to print them with new line like below:



Quote:
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

I know i did wrong but i use simple logic to print them with below.




Quote:
echo $userlogin | awk -F ' ' '{print $13$14$15$16$17$18}'

echo $userlogin | awk -F ' ' '{print $19$20$21$22$23$24}'

echo $userlogin | awk -F ' ' '{print $25$26$27$28$29$30}'

echo $userlogin | awk -F ' ' '{print $25$26$27$28$29$30}'

Did you try something simple like?


Code:
sed 's/, name/\nname/g' yourfile.txt

Code:
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

Code:
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:


Quote:
++ osascript -e 'tell application "System Events" to get properties of every login item'
+ userlogin='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'
+ echo 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
+ sed 's/, name/\nname/g'
name: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
Quote:
sed 's/, name/\nname/g' ~/Desktop/userlogin.txt
name:Pages.app, 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
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.



Code:
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 falsennameTry a verbatim new line char:

Code:
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.
