'How to parse output of bash script in CLI

I'm running following bash script

#!/bin/bash
echo Running RatiosUITests

xcodebuild \
 test \
 -project Ratios.xcodeproj \
 -scheme RatiosUITests \
 -destination 'platform=iOS Simulator,name=iPhone 13 mini'
 
 
 
variable=RatioUITest.sh | grep 'Test session results, code coverage, and logs:'|cut -f2 -d 'T'
echo $variable

it gives me tons of output:

...
2022-04-29 15:34:17.765 xcodebuild[4331:5066596] [MT] IDETestOperationsObserverDebug: 58.666 elapsed -- Testing started completed.
2022-04-29 15:34:17.765 xcodebuild[4331:5066596] [MT] IDETestOperationsObserverDebug: 0.000 sec, +0.000 sec -- start

Test session results, code coverage, and logs:
                         /Users/dmitrijsokolov/Library/Developer/Xcode/DerivedData/Ratios-caehxfsclkooshchojmcmrcadomd/Logs/Test/Test-RatiosUITests-2022.04.29_15-33-18-+0300.xcresult

Failing tests:
 RatiosUITests:
...

And I want to store url of the file in a variable url line I want is on the next line after "Test session results, code coverage, and logs:" it's that one /Users/dmitrijsokolov/Library/Developer/Xcode/DerivedData/Ratios-caehxfsclkooshchojmcmrcadomd/Logs/Test/Test-RatiosUITests-2022.04.29_15-33-18-+0300.xcresult it's changing all the time so I want to parse that file address.

Code with cut not working properly, please help(

Solution 1:[1]

Just grep it with this:

grep -oP '(?<=start_patern).*(?=end_patern)'

-o, --only-matching

This will select your text, but without this border patterns

adrian@pc:/tmp> cat your_text | grep -oP '(?<=/Users).*(?=.xcresult)'

/dmitrijsokolov/Library/Developer/Xcode/DerivedData/Ratios-caehxfsclkooshchojmcmrcadomd/Logs/Test/Test-RatiosUITests-2022.04.29_15-33-18-+0300

To put it onto variable do

adrian@pc:/tmp> var=$(cat your_text | grep -oP '(?<=/Users).*(?=.xcresult)')

adrian@pc:/tmp> echo $var

/dmitrijsokolov/Library/Developer/Xcode/DerivedData/Ratios-caehxfsclkooshchojmcmrcadomd/Logs/Test/Test-RatiosUITests-2022.04.29_15-33-18-+0300

Then to concatenate parts back

adrian@pc:/tmp> complete_var="/Users${var}.xcresult"

adrian@pc:/tmp> echo $complete_var
 
/Users/dmitrijsokolov/Library/Developer/Xcode/DerivedData/Ratios-caehxfsclkooshchojmcmrcadomd/Logs/Test/Test-RatiosUITests-2022.04.29_15-33-18-+0300.xcresult

Suggestion 1

Assuming file name is in same line with Test session results, code coverage, and logs:

variable=$(RatioUITest.sh | awk -F":" '/Test session results, code coverage, and logs:/{print $2}')

Suggestion 2

Assuming file name is in next line after Test session results, code coverage, and logs:

variable=$(RatioUITest.sh | awk '/Test session results, code coverage, and logs:/{line=NR}NR==(line+1){print}')
