Today, I found one interesting command that could record everything in a file. Here’s the demonstration of “script” command.
Step 1:
Start script command and record every thing in “record” file.
saggi@saggi-A6200:~/Desktop$ script -a record
Script started, file is record
Now, do whatever you do in command and see the beauty of “script” command. See demo below:

saggi@saggi-A6200:~/Desktop$ uname -a

saggi@saggi-A6200:~/Desktop$ touch saggi

saggi@saggi-A6200:~/Desktop$ exit
exit
Script done, file is record

(Now open the file record. You’ll see all the command and result recorded in record file.)
