24$FUNCTION history_builtin-
25$DEPENDS_ON HISTORY-
26$SHORT_DOC history [-c] [-d offset] [n] or history -anrw [filename] or history -ps arg [arg...]-
27Display or manipulate the history list.-
28-
29Display the history list with line numbers, prefixing each modified-
30entry with a `*'. An argument of N lists only the last N entries.-
31-
32Options:-
33 -c clear the history list by deleting all of the entries-
34 -d offset delete the history entry at position OFFSET. Negative-
35 offsets count back from the end of the history list-
36-
37 -a append history lines from this session to the history file-
38 -n read all history lines not already read from the history file-
39 and append them to the history list-
40 -r read the history file and append the contents to the history-
41 list-
42 -w write the current history to the history file-
43-
44 -p perform history expansion on each ARG and display the result-
45 without storing it in the history list-
46 -s append the ARGs to the history list as a single entry-
47-
48If FILENAME is given, it is used as the history file. Otherwise,-
49if HISTFILE has a value, that is used, else ~/.bash_history.-
50-
51If the HISTTIMEFORMAT variable is set and not null, its value is used-
52as a format string for strftime(3) to print the time stamp associated-
53with each displayed history entry. No time stamps are printed otherwise.-
54-
55Exit Status:-
56Returns success unless an invalid option is given or an error occurs.-
