tcsh 命令

常用示例

说明

tcsh is an enhanced version of the Berkeley C shell (csh). It provides a command-line editor, programmable word completion, spelling correction, history mechanism, job control, and C-like syntax. Interactive shells read ~/.tcshrc (or ~/.cshrc) on startup. Login shells additionally read ~/.login and execute ~/.logout on exit. The shell supports command history with ! syntax, aliases, and shell variables. Features include filename completion with Tab, command history editing, directory stack manipulation with pushd/popd, and programmable completions for commands and arguments.
