## Example of use of the find command
##

find ~/ -name 'core*' -exec rm {} \;
#  Removes all core dump files from user's home directory.

find /home/bozo/projects -mtime 1
#  Lists all files in /home/bozo/projects directory tree that were modified within the last day.
#
#  mtime = last modification time of the target file
#  ctime = last status change time (via 'chmod' or otherwise)
#  atime = last access time

DIR=/home/bozo/junk_files
find "$DIR" -type f -atime +5 -exec rm {} \;
#                                      ^^
#  Curly brackets are placeholder for the path name output by "find."
#
#  Deletes all files in "/home/bozo/junk_files" that have not been accessed in at least 5 days.
#
#  "-type filetype", where
#  f = regular file
#  d = directory, etc.
#  (The 'find' manpage has a complete listing.)

find . -name '*.*' -mtime +7 -exec echo '{}' \;
find . -name "*.*" -mtime +7 -exec echo '{}' \;

#  Give exactly the same results

#  But:

find . *.* -mtime +7 -exec echo '{}' \;
#  Gives the same but DOUBLE (i.e. reports twice, once with path in name and once just plain file name)

find . -name '*.*' -type f -mtime +7 -exec echo '{}' \;
#  Displays single instance of the files reports with the prepending directory clash

find . -name "*.*" -type f -mtime +7 -exec echo '{}' \;
#  ditto

find . *.* -type f -mtime +7 -exec echo '{}' \;
# Reports twice again (i.e. reports twice, once with path in name and once just plain file name)
