[SOLVED] terminal 'history'

i  have used the terminal command 'history' a few times and wonder that I can not edit in the list
What I would like to have is a list where every single command that has been used appears only once, is that possible ?

Re: [SOLVED] terminal 'history'

yes, that's get me part of the way
How do I get a numbered list with just one example of each used command
so I can use  !111 to enable a command

Re: [SOLVED] terminal 'history'

sort -u  ~/.bash_history > temporary-file
cat temporary-file > ~/.bash_history
nl temporary-file > index_file

Use the index file for reference. You don't want to number the lines in .bash_history, but you do want a numbered list.
This will work until you reach the limit of bash_history, and the commands start scrolling off the top. See 'man bash' for the HISTSIZE setting if you want to change the number of lines that get saved. I don't remember what the default is - maybe 1000 or 2000.
