有没有办法从 valgrind 中获取泄漏摘要？

Question

I am trying to make a script that will compile a.cpp file, run a leak check on the output, and then prompt the user whether to run the output or not automatically, and all of it works from that standpoint.

The problem is that I just want the

LEAK SUMMARY:
    definitely lost: ...
    possibly lost: ...
    still reachable: ...
    suppressed: ...

section of the output. I tried piping valgrind through grep, but it's not filtering properly. Any ideas?

Code (.sh)

clear; clear; clear; g++ *.cpp -o outputFile && echo "Compilation Successful!" && ( valgrind --leak-check=full ./output | grep  "LEAK\|lost:\|reachable\|suppressed\|possible" ) && {
echo "Do you want to run this file as compiled? (y/n)"
read decision
if [ "$decision" == "y" ]
then
./output
fi
echo "Script ended."
exit
}
echo "Something went wrong!"
exit

Output:

Compilation Successful!
{full valgrind output}
Something went wrong!

The something went wrong line seems to be caused by grep though since the rest of the script functions properly if the grep statement is removed.

Desired output:

Compilation Successful!
LEAK SUMMARY:
    definitely lost: ...
    possibly lost: ...
    still reachable: ...
    suppressed: ...
Do you want to run this file as compiled? (y/n)
>y
{program output displayed}
Script ended.

I have fixed the code with this:

clear; clear; clear; g++ *.cpp -o outputFile && echo "Compilation Successful!" && valgrind --leak-check=full ./outputFile &> CompileTempFile.txt && grep -A5 "LEAK SUMMARY:" CompileTempFile$
echo "Do you want to run this file as compiled? (y/n)"
read decision
if [ "$decision" == "y" ]
then
./output
fi
rm CompileTempFile.txt
echo "Script ended."
exit
}
rm CompileTempFile.txt
echo "Something went wrong!"
exit

EDIT: I updated the code, so I thought I'd share my current (smarter) version. :)

clear; clear; clear; g++ *.cpp -o outputFile && echo "Compilation Successful!" && echo "Running a leak test" && valgrind --leak-check=full ./outputFile &> CompileTempFile.txt && echo "Memory test completed!" && egrep -A5 "LEAK SUMMARY|no leaks are possible" CompileTempFile.txt && {
echo "Do you want to run this file as compiled? (y/n)"
read decision
if [ "$decision" == "y" ]
then
./outputFile
fi
rm CompileTempFile.txt
echo "Script ended."
exit
}
rm CompileTempFile.txt
echo "Something went wrong!"
exit
