A history of command is only kept for interactive sessions, it does not capture the commands and subscripts invoked by a script. But you stated:

which would be done with command >> filename as I stated above, which appends the standard ouput result from the script (when executed at the terminal) into the specified file. Please note that the standard output of any command is not put into the history file, it is just a stream of data. And there is no "pasting", the data is just going to be added to a file.

There are a few different ways to capture what commands are invoked by a script. The easiest would be run the script in "xtrace" mode, as follows:
Code:
sh -x command 2> command.xtrace >> filename

or by adding the "-x" option to the shebang line at the top of the script.

NAME
script -- make typescript of terminal session SYNOPSIS
script [-a] [-f] [-q] [-t] [file] DESCRIPTION
Script makes a typescript of everything printed on your terminal. It is useful for students who need a hardcopy record of an interactive session as proof of an assignment, as the typescript file can be printed out later with lpr(1). If the argument file is given, script saves all dialogue in file. If no file name is given, the typescript is saved in the file typescript. Options: -a Append the output to file or typescript, retaining the prior contents. -f Flush output after each write. This is nice for telecooperation: One person does `mkfifo foo; script -f foo' and another can super- vise real-time what is being done using `cat foo'. -q Be quiet. -t Output timeing data to standard error. This data contains two fields, separated by a space. The first field indicates how much time elapsed since the previous output. The second field indicates how many characters were output this time. This information can be used to replay typescripts with realistic typing and output delays. The script ends when the forked shell exits (a control-D to exit the Bourne shell (sh(1)), and exit, logout or control-d (if ignoreeof is not set) for the C-shell, csh(1)). Certain interactive commands, such as vi(1), create garbage in the typescript file. Script works best with commands that do not manipulate the screen, the results are meant to emulate a hardcopy terminal. ENVIRONMENT
The following environment variable is utilized by script: SHELL If the variable SHELL exists, the shell forked by script will be that shell. If SHELL is not set, the Bourne shell is assumed. (Most shells set this variable automatically). SEE ALSO
csh(1) (for the history mechanism), replay(1). HISTORY
The script command appeared in 3.0BSD. BUGS
Script places everything in the log file, including linefeeds and backspaces. This is not what the naive user expects. Linux July 30, 2000 Linux
