Команда script
Records everything printed on your screen. The record is recorded to the filename, if no filename is specified results are recorded to the file transcript.
script [-a] filename
| -a | Append the session record to filename, rather than overwrite it. |
| filename | The name of the file that you wish the results to be stored. |
script myfile.txt - Will log all results into the file myfile.txt. This will open a sub-shell and records all information through this session. The script ends when the forked shell exits (user types exit) or when CTRL-D is typed.
Note: If the script file is deleted during the script process the script still remains in memory however will not log the results.
