More easily, just escape the quotes in the string.

const char cTestPrag[]=" kill -9 `ps -ef | grep textedit | grep -v \"grep\"| awk '{print $2}'| xargs` ";

You cannot imbed " in a quoted string. You can escape them \" (which linters - code checkers - usually complain about), or you can use sprintf to place them in the string as single characters.

man sprintf

what is the need for quoting grep as "grep" ?

is that going to make any difference ? It won't.

maybe its not working on sun but whats about 'killall' ?
