Find files containing phrase(s) and do some action on it (for example move to different folder):
1 - test1: grep -Ril Transmission .>f
2 - test2: while read f;do echo "$f";done < f
3 - action (in this case move files to defined common folder): while read f;do mv "$f" /destination/folder/;done < f

- grep command withhout -R parameter would not search recursively.
- the dot at the end of the grep command searching in current directory, else define other path instead of the dot, like /home/user/filestosearch
- To search for multiple phrases, add "E" switch, for example grep -ilE "phrase1|phrase2"
