It won't display the shell prompt. But it will display the commands and results. So if you want shell prompt as well, then using script is the best option.

Here is how you can use script command:-
Code:
script collect_log

This will log all results into the file collect_log. This will open a sub-shell and records all information through this session. The script ends when the forked shell exits. I hope this helps.

Oh, but it seems useless for me, I just want to make the function in my script.

Code:
#!/bin/bash
LOG=mylog
define a fuction collect_log ---------> here
cd /root/;ls |grep .sh
collect_log 
lspci |grep 0000
collect_log

script is the right approach, but if you don't want to use it, then run bash in interactive mode with option "-i" and read all the commands through stdin.
Code:
echo 'cd /root/;ls |grep .sh
lspci |grep 0000' | bash -i > mylog 2>&1
# or
bash -i < file-with-commands > mylog 2>&1
