The C shell can also read commands from a file, called a script. Like all Unix shells, it supports filename wildcarding, piping, here documents, command substitution, variables and control structures for condition-testing and iteration. What differentiated the C shell from others, especially in the 1980s, were its interactive features and ...
Hamilton C shell and Cygwin bash on Windows 7, showing the use of recursion for factoring. The original C shell uses an ad hoc parser. This has led to complaints about its limitations. It works well enough for the kinds of things users type interactively but not very well for the more complex commands a user might take time to write in a script.
It is essentially the C shell with programmable command-line completion, command-line editing, and a few other features. Unlike the other common shells, functions cannot be defined in a tcsh script and the user must use aliases instead (as in csh). It is the native root shell for some BSD-based systems, including FreeBSD 13 and earlier.
CH can interact with existing C/C++ libraries and call C/C++ functions from CH script. [16] As a C/C++ interpreter, CH can be used as a scripting engine and extension language for applications. Pointers to arrays or variables can be passed and shared in both C-compiled and CH scripting contexts. One example of an embedded CH scripting ...

C Shell running on Windows Services for UNIX. The C shell is a command processor which is typically run in a text window, allowing the user to type and execute commands. The C shell can also read commands from a file, called a script
shc takes a shell script which is specified on the command line by the -f option and produces a C source code of the script with added encryption. The generated source code is then compiled and linked to produce a binary executable. It is a two step process where, first, it creates a filename.x.c file of the shell script file filename.
