Why is csh bad?
Resolved: The csh is a tool utterly inadequate for programming, and its use for such purposes should be strictly banned. The csh is seductive because the conditionals are more C-like, so the path of least resistance if chosen and a csh script is written. …
How do I run a csh file in Terminal?
Your best bet is simply to write a new version of your csh script as an sh script, and source or . it from the calling sh script. (csh treats the shell array variable $path specially, tying it to the environment variable $PATH . sh and its derivatives don’t do that, they deal with $PATH itself directly.)
What does #!/ Bin csh do?
When you type in a command at the Unix prompt, you are interacting with the shell. E.g., #!/bin/csh refers to the C-shell, /bin/tcsh the t-shell, /bin/bash the bash shell, etc. You can change your command shell with the chsh command.
Where do I find the command file for CSH?
An instance of csh begins by executing commands from the file /etc/csh.cshrc and, if this is a login shell, /etc/csh.login. It then executes commands from .cshrc in the home directory of the invoker, and, if this is a login shell, the file .login in the same location.
Can a csh script be read by a tcsh script?
Even if tcsh is your login shell, csh may read your .cshrc file occasionally. Some programs are implemented as csh scripts, so .cshrc might be read when csh is invoked to execute the script. Therefore, you need to be careful about putting tcsh-specific commands in your .cshrc file.
What’s the difference between csh and tcsh shell?
If the files exist, the shell executes their commands before displaying its first prompt. tcsh reads startup files a little differently than csh. If you have a file named .tcshrc in your home directory, tcsh reads that instead of .cshrc.
Where does the logout command in csh go?
Finally each command in the current line is executed. When a login shell terminates it executes commands from the files .logout in the user’s home directory and /etc/csh.logout.
