You can try the following command :
grep -R -f filename.txt /home/* will search any pattern inside your
filename.txt file and match it recursively against all files inside your home folder. You'll get an output like this :
#here my filename contains the entries bash and Bingo
$grep -R -f filename.txt /home/*
/home/user/.bash_history:awk -v RS=END_WORD '/Bingo1/ && /Bingo2/' test2.txt | grep -o 'Pokeman.*'
grep will output the file name and the full line containing your pattern.
If you only want to display the pattern that was found, try the following command :
#here the -o flag only displays the matched values, and -n adds the line number
$grep -R -o -n -f test /home/*
