E.g. at the end of the session for each day I want to create a history file with the date attached at the end.

So, say, history > history07162012.txt or something like that.

I would suggest using a standard timestamp instead of your US specific and unsortable one, i.e. history20120716.txt by using date +%Y%m%d – jlliagre Jul 17 '12 at 11:53

Assuming history files are hidden (beginning with .), I would do like:

ls -1 ~/.*history

With output:

/home/birei/.bash_history
/home/birei/.mysql_history
/home/birei/.ptksh_history
/home/birei/.sqlite_history
/home/birei/.xsh2_history
/home/birei/.xsh_history

Execute:

for hist_file in ~/.*history; do cp "$hist_file" "$hist_file$(date +%m%d%Y).txt"; done

And then:

ls -1 ~/.*history*

With following output:

/home/birei/.bash_history
/home/birei/.bash_history07172012.txt
/home/birei/.mysql_history
/home/birei/.mysql_history07172012.txt
/home/birei/.ptksh_history
/home/birei/.ptksh_history07172012.txt
/home/birei/.sqlite_history
/home/birei/.sqlite_history07172012.txt
/home/birei/.xsh2_history
/home/birei/.xsh2_history07172012.txt
/home/birei/.xsh_history
/home/birei/.xsh_history07172012.txt

I hope it can be useful for your question.
