cat /home/name/*.txt

Answer 3

find /home/lalala -type f -exec cat {} \;
find- find
/home/lalala - where
-type f- file
-exec execute command (find feature)
cat - print file
{}path to the file that find find
\;closes find escaped
if you need to find something in these files instead of cat put grep with what to look for.
