You can also use script to capture an entire session.

In the script, the command line parameters are $1, $2, etc. The output
of a command can be put into a command line by using backquotes or $():
myscript `mycommand_that_outputs_two_words`
Then the script:
#!/bin/bash
# myscript -- echoes the first argument
if [ -z "$1" ]
then
echo No arguments supplied"
exit 1
else
echo $1
fi
