shc is a shell script compiler for Unix-like operating systems written in the C programming language. The Shell Script Compiler (SHC) encodes and encrypts shell scripts into executable binaries. Compiling shell scripts into binaries provides protection against accidental changes and source code modification, and is a way of hiding shell script ...
Hamilton C shell and Cygwin bash date loops. Lacking fork or a high performance way to recreate that functionality, Hamilton uses the Windows threads facilities instead. [6] [8] When a new thread is created, it runs within the same process space and it shares all of the process state. If one thread changes the current directory or the contents ...
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. It has been widely distributed, beginning with the 2BSD release of the Berkeley Software Distribution (BSD) which Joy first distributed in 1978.
There are many variants of Unix shell: Bourne shell sh. Almquist shell (ash) Debian Almquist shell (dash) Bash (Unix shell) bash; KornShell ksh. Z shell zsh; C shell csh. TENEX C shell tcsh; Ch shell ch; Emacs shell eshell; Friendly interactive shell fish; PowerShell pwsh; rc shell rc, a shell for Plan 9 from Bell Labs and Unix; Stand-alone ...
Cygwin's default user interface is the bash shell running in the Cygwin console. The DLL also implements pseudo terminal (pty) devices. Cygwin ships with a number of terminal emulators that are based on them, including mintty, rxvt/urxvt, and xterm. The version of GCC that comes with Cygwin has various extensions for creating Windows DLLs, such ...
Implementations of the Unix shell are also available as part of the POSIX sub-system, [42] Cygwin, MKS Toolkit, UWIN, Hamilton C shell and other software packages. Available shells for these interoperability tools include csh, ksh, sh, Bash, rsh, tclsh and less commonly zsh, psh; Implementations of PHP have a shell for interactive use called ...
For example, the macro CC is frequently used in makefiles to refer to the location of a C compiler. If used consistently throughout the makefile, then the compiler used can be changed by changing the value of the macro rather than changing each rule command that invokes the compiler. Macros are commonly named in all-caps:
A shell memory leak was fixed on October 10, 1986, and MPW 1.0.1 was born. MPW 2.0 was completed on July 20, 1987. MPW 3.0 was done November 30, 1988 and included a completely new C compiler. [8] Around the same time, the beta version of the C++ compiler as well as MacApp 2.0 (for Object Pascal) were made available. [9]
