I have mentioned below cmd on top of the script

exec > >(tee -a "$log_file") 2>&1
# (all remaining script part here)

The shell script is user interactive, so I want the inputs given by user are also to be redirected in same file. How this can be achieved?

  • The user input goes into the commands reading the input, not into the log file. If you want to capture the whole session, run it with the script utility. Commented Apr 8, 2021 at 6:41

  • Install the script utility, if it's not already installed, then run script -c ./myshellscript.sh (where myshellscript.sh is the name of your script). You would not need the exec command in the script. Commented Apr 8, 2021 at 7:18
  • Similar, but placing input/output redirections outside the script: unix.stackexchange.com/q/639326/315749 (plus a script example). Commented Apr 8, 2021 at 8:56
