有沒有辦法從 valgrind 中獲取泄漏摘要？

Question

我正在嘗試制作一個腳本來編譯 a.cpp 文件，對 output 運行泄漏檢查，然后提示用戶是否自動運行 output，所有這些都從這個角度工作。

問題是我只想要

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

output 的部分。 我嘗試通過 grep 管道 valgrind，但它沒有正確過濾。 有任何想法嗎？

代碼 (.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!

出現問題的行似乎是由 grep 引起的，盡管如果刪除 grep 語句，腳本的 rest 會正常運行。

所需的 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.

我已經用這個修復了代碼：

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

編輯：我更新了代碼，所以我想我會分享我當前的（更智能的）版本。 :)

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
