Hi all, I would like to have my shells to be compliant to those things. 1. A large number of slot for history so I don't lose command. 2. Each shell has proper history, so command issued in one shell are not viewed on others 3. But when shell is closed, commands are appended to history files, and not overwritten Is this possible? Where ca I act to change default behavior of shell history? Tnx to all Ambrogio
