# find with grep
# + concatinates results and runs the command once, faster
find . -name "*.txt" -exec grep -l "somename" '{}' '+'
# run a command for each result individually
find . -name "*.txt" -exec basename '{}' \';' | column
# case insensitive
find -iname "SoMeNaMe.TxT
# file or dir
find -type f
find -type d
# define file owner
find -user Bob
# define file group
find -group wheel

# find by size
