You can append these commands to the bottom of the history file to access them easier with the Up key:
sort ~/.bash_history|uniq -c|sort -n|tail -n 10|tr -s " "|cut -d' ' -f3- >> ~/.bash_history2sort ~/.bash_history|uniq -c|sort -n|tail -n 10 -
Only the first appearance of a repeated command in the history will be kept. Otherwise, if you prefer to keep last occurrence of a repeated command then maybe you can achieve that by including reverse input/output i.e with 'tac' command in expression above. To see statistics of removed repeated commands:
diff --suppress-common-lines -y ~/.bash_history.bak ~/.bash_history|uniq -c|sort -n|tr -s " "|sed '/^ 1/d'|grep '<'0cp -a ~/.bash_history ~/.bash_history.bak && perl -ne 'print unless $seen{$_}++' ~/.bash_history.bak >~/.bash_history - ‹ First < 9 10 11 12 13 > Last ›
