The C shell (csh or the improved version, tcsh) is a Unix shell created by Bill Joy while he was a graduate student at University of California, Berkeley in the late 1970s.
In computing, a command is a directive to a computer program acting as an interpreter of some kind, in order to perform a specific task.
A computer file is a computer resource for recording data discretely in a computer storage device.
In computing, a directory is a file system cataloging structure which contains references to other computer files, and possibly other directories.
An environment variable is a dynamic-named value that can affect the way running processes will behave on a computer.
In some programming languages, eval is a function which evaluates a string as though it were an expression and returns a result; in others, it executes multiple lines of code as though they had been included instead of the line including the eval.
In computing, executable code or an executable file or executable program, sometimes simply referred to as an executable or binary, causes a computer "to perform indicated tasks according to encoded instructions," as opposed to a data file that must be parsed by a program to be meaningful.
A filename (also written as two words, file name) is a name used to uniquely identify a computer file stored in a file system.
The full point or full stop (British and broader Commonwealth English) or period (North American English) is a punctuation mark.
In computing, a hidden folder (sometimes hidden directory) or hidden file is a folder or file which filesystem utilities do not display by default when showing a directory listing.
Modular programming is a software design technique that emphasizes separating the functionality of a programme into independent, interchangeable modules, such that each contains everything necessary to execute only one aspect of the desired functionality.
In computer programming, a parameter (often called formal parameter or formal argument) is a special kind of variable, used in a subroutine to refer to one of the pieces of data provided as input to the subroutine.
A path, the general form of the name of a file or directory, specifies a unique location in a file system.
PATH is an environment variable on Unix-like operating systems, DOS, OS/2, and Microsoft Windows, specifying a set of directories where executable programs are located.
The slash is an oblique slanting line punctuation mark.
source is a Unix command that evaluates the file following the command, as a list of commands, executed in the current context.
A Unix shell is a command-line interpreter or shell that provides a traditional Unix-like command line user interface.
