tset 命令

常用示例

说明

tset initializes the terminal according to the terminal type specified in the $TERM environment variable or on the command line. It sets terminal modes, sends initialization strings, and can configure special characters like erase and kill. If neither -c nor -w is specified, both are assumed. When invoked as reset, the command sets terminal modes to "sane" values: enables cooked and echo modes, disables raw mode, enables newline translation, and resets special characters to defaults. This is useful for recovering from programs that leave the terminal in an abnormal state. The command determines terminal type by checking: command-line argument, $TERM variable, /etc/ttys entry (on BSD), or the default type "unknown". It then sends appropriate initialization sequences from the terminfo database. The -s option outputs shell commands to set TERM, useful in login scripts when the terminal type may change.
