GNU FINDUTILS is a set of utilities used to compare files for differences.
The find utility recursively descends the directory hierarchy for each path seeking files that match a Boolean expression written in the primaries given below.
locate searches one or more databases of file names and displays the file names that contain the pattern.
updatedb updates thelocate database.
xargs constructs a command line consisting of the command and initial argument operands specified followed by as many arguments read in sequence from standard input as will fit in length and number constraints specified by the options. xargs then invokes the constructed command line and waits for its completion. This sequence is repeated until an end-of-file condition is detected on standard input or an invocation of a constructed command line returns an exit status of 255.
find [OPTIONS] PATH EXPRESSION
locate [OPTIONS] PATTERN
xargs [OPTIONS] [ COMMAND [INITIAL-ARGUMENTS] ]
