If you want to capture something like commands when you are installing some software, compiling some opensource codes or just want to see debug logs printed on the terminal by some program, there is command “script” which does all the work very efficiently for us. Just open a terminal, and type below command before you want things to be captured, $ script --timing=time.txt script.log Script started, file is script.log Above command starts the screen commands recording into log file script.log. Now type the commands or do the work you want to do on the terminal.

Execution & Command Syntax

Terminalbash
gcc version 5

Technical Implementation Details

As an example, we typed below commands, $ pwd /home/devbee/wp $ cat /proc/version Linux version 4.4.0-71-generic (buildd@lcy01-27) (gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.4) ) #92-Ubuntu SMP Fri Mar 24 12:58:08 UTC 2017 $ date Sun Dec 31 09:48:05 IST 2017 $ time real 0m0.000s user 0m0.000s sys 0m0.000s Now, lets say, you are done with your recording, then type “exit” to stop script command running, $ exit exit Script done, file is script.log Now to replay script recording using “scriptreplay” command, use below command, $ scriptreplay --timing=time.txt script.log

Gotchas and Common Issues

  • Permission Verification - confirm execution permissions and path variables before invoking system binaries.

  • Version Compatibility - check software version release notes for deprecated flags or syntax changes.

  • Log Monitoring - inspect system logs (journalctl or /var/log) to troubleshoot execution failures.

Following these steps ensures clean configuration, proper security boundaries, and reliable execution for record and replay linux terminal commands.
