Output of the record screen using the script command in Linux

In Linux, use the script command to record the output of the screen-Linux Enterprise Application-Linux server application information. The following is a detailed description. We use scripts to record screen output. This is used on the Linux platform. script Commands in Solaris and AIX do not have the-f option.

-F indicates that only when the buffer zone is full can the content of the previous buffer full be displayed on another terminal. Even if an exception exits, the log can still be recorded normally. Use the script-f screen. log command.

If mkfifo screen. log is used on the first terminal (this command is generally not used) and script-f screen. log is used. Find the screen. log File on another terminal, and use tail-f screen. log to scroll out your output on the first terminal in real time.

If there is no-f, only when the buffer zone is full can the content of the previous buffer full be displayed on another terminal.

The first window:

This method can also be used in teaching. The instructor uses the script command to record operation logs. The student uses the tail-f command to view the instructor's explanations in real time.
