hist

hist [options ] [first [last ]]
hist -s [old = new ] [command ]

ksh93 only. Display or edit commands in the history list. (Use only one of -l or -s .) first and last are numbers or strings specifying the range of commands to display or edit. If last is omitted, hist applies to a single command (specified by first ). If both first and last are omitted, hist edits the previous command or lists the last 16. The second form of hist takes a history command , replaces old string with new string, and executes the modified command. If no strings are specified, command is just reexecuted. If no command is given either, the previous command is reexecuted. command is a number or string like first . See the examples in the earlier section "Command History."
