| | Shell (computing) - Wikipedia, the free encyclopedia |
 | | In computing, a shell is a piece of software that essentially provides a kind of interface for end-users. | | | Older versions also include Program Manager which was the Shell for the 3.x series of Microsoft Windows. | | | The best choice is often determined by the way in which a computer will be used. |

| | C Shell Programming |
| | Shell scripts are often written to handle some of the more tedious tasks that a user encounters on a regular basis. | | | A simple C shell script could be a list of Unix commands that archives and compresses the users home directory and copies it to a specified mounted disk partition for storage | | | This could be any shell or even other scripting environments such as perl (Practical Extraction and Report Language) [1] or tcl (Tool Command Language) [2] which are Unix scripting languages but not shells (at least not interactive shells like those discussed in this book). |

| | csh -- C Shell, a shell (command interpreter) with C-like syntax |
| | As the shell searches each directory in the search path, it appends each of the extensions in the list, in turn, to the command name and if it matches a file name in that directory, that file is executed as though it had that extension. | | | The arguments are read as input to the C Shell and the resulting command(s) are executed in the context of the current shell. | | | Without this option, C Shell is only interactive when its input and output are terminals. |

| | Csh Programming Considered Harmful |
| | Lack of proficiency in the Bourne shell has been known to cause errors in /etc/rc and.cronrc files, which is a problem, because you *must* write these files in that language. | | | In the Bourne shell, this VAR=foo cmds args is the same as (export VAR; VAR=foo; cmd args) or csh's (setenv VAR; cmd args) You can't use :t, :h, etc on envariables. | | | In the Bourne shell, you might say: echo "$0: cannot find $file" 1>and2 but in the csh, you can't redirect stdout out stderr, so you end up doing something silly like this: sh -c 'echo "$0: cannot find $file" 1>and2' 1b. |

| | Help Files: C Shell: Internals |
| | When you login, Unix finds the C shell program in the file "/bin/csh" and starts it running as a process on your terminal. | | | Also, if the first command word begins with a /, the shell considers it to be the name of the program file to execute, for example, the command "/usr/ucb/vi.cshrc" would work. | | | The Unix kernel requires the C shell -- in fact, requires all programs that run other programs -- to use execl. |

| | UNIX shell differences and how to change your shell (Monthly Posting) |
| | Further information The Bourne shell, the C-Shell and the Korn Shell (if you have it) are all distributed as standard with your UNIX operating system, information on these should come with your operating system, bug reports etc should be sent to your operating system vendor. | | | The theory behind the change was fairly good, the new input language was to resemble C, the language in which UNIX itself was written, but they made a complete mess of implementing it. | | | It had (and still does) a very strong powerful syntactical language built into it, with all the features that are commonly considered to produce structured programs; it has particularly strong provisions for controlling input and output and in its expression matching facilities. |

| | Common (system-wide) shell start-up files can be used to set up a convenient environment for all users on the system, and personal start-up files allow to create an individual working environment. | | | This means, each program started by the shell on a user's request, inherits a copy of the set of environment variables the shell owns. | | | Worthwhile to remember are especially the variables PATH, the value of which defines the search path for executable files in the system, and SHELL containing the name of the shell to invoke whenever a utility program needs to start a shell. |

| | Fewer ways to test for missing variables The C shell provides a way to test if a variable exists - using the $?var name: % if ($?A) then % echo variable A exists % endif However, there is no simple way to determine if the variable has a value. | | | The C shell allows you to repeat only the first part of a complex command, like the single line with the "if" statement. | | | The C shell provides one way to read a line: % set ans = $< The trouble is - this ALWAYS reads from standard input. |

| | Making C Shell Jump Through Hoops @ LINUXWORLD MAGAZINE |
| | There are couple of basic redirections that you'll want to know how to accomplish within the Csh environment, the most important of which is to redirect stderr (standard error) to the same place as stdout (standard out). | | | My focus here is ultimately on shell scripting, so I have to point out that the vast majority of Linux shell scripts are written in a Bourne Shell-compatible scripting environment, whether it's directly in /bin/sh or in a more sophisticated environment like Bash. | | | This time I'll turn my attention to the C shell with its different command-line syntax. |
