The Shell Script Compiler (SHC) converts linux shell scripts directly into executable binaries. Compiling shell scripts into binaries provides protection against accidental changes, source modification and renders a way of hiding source code written in linux shell scripting language.〔http://www.linux-magazine.com/Online/Features/SHC-Shell-Compiler〕 == Mechanism == SHC takes a shell script which is specified on the command line by $(filename)$ option and produces a C source code of the script. The generated source code is then compiled and linked to produce a binary executable. Thus it's a two step process where, at first step, it creates a $filename.x.c$ file of the shell script file $filename$. Then it is compiled with $cc\; -\$CFLAGS\; filename.x.c$ and thus build the binary from a C source code with the default C compiler available in any system.〔 The compiled binary will still be dependent on the shell specified in the first line of the shell code (i.e. Shebang: #!/bin/sh or such), thus shc does not create completely independent binaries.〔 shc itself is not a compiler such as the C compiler, it rather encodes and encrypts a shell script and generates C source code with the added expiration capability. It then uses the system C compiler to compile the source shell script and build a stripped binary which behaves exactly like the original script. Upon execution, the compiled binary will decrypt and execute the code with the shells' -c option.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Shc the shell script compiler」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
