Search the system for files that were modified within the last two

days (good candidates for backing up):

find / -mtime -2 -print

Recursively grep for a pattern down a directory tree:

find /book -print | xargs grep '[Nn]utshell'

If the files kt1 and kt2 exist in the current directory, their names

can be printed with the command:

$ find . -name 'kt[0-9]'

./kt1

./kt2

Since the command prints these names with an initial ./ path, you

need to specify the ./ when using the -path option:

$ find . -path './kt[0-9]'

./kt1

./kt2

The -regex option uses a complete pathname, like -path, but treats

the following argument as a regular expression rather than a glob

pattern (although in this case the result is the same):

$ find . -regex './kt[0-9]'

./kt1

./kt2

finger

Display data about one or more users, including information listed

in the files .plan and .project in each user’s home directory. You can

specify each user either as a login name (exact match) or as a first

or last name (display information on all matching names).

Networked environments recognize arguments of the form

user@host and @host.

Options

-l Force long format (default): everything included by the -s

option, as well as home directory, home phone, login shell,

mail status, .plan, .project, and .forward ...
