If and while commands can get file redirection anywhere. The following is valid in the Bourne shell: Once you learn the principles, the behavior is predictable.

The C shell does not have a true parser. Instead, the code executes one section for the if command, and another for the while command. What works for one command may not work for another.

The if command above cannot be done in the C shell. There are two file redirections, and the C shell can't do either. Also, in the C shell, certain words must be the first word on the line. Therefore you might try something that works with one command, only to discover that it doesn't work on other commands.

I've reported a lot of bugs to Sun, and to their credit, many have been fixed.

Try the same code on other systems, however, and you might get syntax errors. The parsing problem is also true with shell built-in commands. Combine them, and discover strange messages. Try the following C shell sequence: There are other examples of this. These are the types of problems that sneak up on you when you don't expect them.

The Bourne shell has the -n flag, which lets you check the script for syntax errors, including branches you didn't take. You can't do this with the C shell.

The C shell seems to act on one line at a time and some syntax errors may not be discovered unless they get executed. Reading one line at a time Sometimes you have to ask a person for input in the middle of a script. Sometimes you have to read some information from a file. The Bourne shell allows you to specify the source of information for each command.

Even though a script is connected to a pipe, you can ask the user for input. The C shell does not have this flexibility.

It has a mechanism to get a line from standard input, but that is all it can do. You cannot have a C shell script get input from both a file and the terminal. File redirection With respect to file redirection, the Bourne shell has no limitations, while the C shell is very limited. With the Bourne shell, you can send standard error to one place, and standard out to another file.

You can discard standard output, but keep the error. You can close any file descriptor, save current ones, and restore them.

The C shell can't do any of these steps.
