Command line history was added to Unix in Bill Joy 's C shell of 1978; Joy took inspiration from an earlier implementation in Interlisp . [ 1 ]
Programmable command-line completion that can help the user type both options and arguments for most used commands, with out-of-the-box support for several hundred commands; Sharing of command history among all running shells; Extended file globbing allows file specification without needing to run an external program such as find
In Unix-like operating systems, find is a command-line utility that locates files based on some user-specified criteria and either prints the pathname of each matched object or, if another action is requested, performs that action on each matched object.
