查看没有行号的终端历史记录

Question

如果没有线路号码，我如何获得Ubuntu终端历史记录？

history

history命令以行号返回前面的命令。我在找这样的东西：

 cd tizen-sdk\tools          
 ls

而不是

924  cd tizen-sdk\tools      
925  ls

Answer 1

您可以使用fc命令代替。来自help fc：

fc: fc [-e ename] [-lnr] [first] [last] or fc -s [pat=rep] [command]
    Display or execute commands from the history list.

    fc is used to list or edit and re-execute commands from the history list.
    FIRST and LAST can be numbers specifying the range, or FIRST can be a
    string, which means the most recent command beginning with that
    string.

    Options:
      -e ENAME  select which editor to use.  Default is FCEDIT, then EDITOR,
            then vi
      -l    list lines instead of editing
      -n    omit line numbers when listing
      -r    reverse the order of the lines (newest listed first)

因此：

fc -ln

您也可以直接查看历史文件，但可能不会更新：

cat "$HISTFILE"

Answer 2

使用以下命令：

history | cut -c 8-

Answer 3

使用awk。

history | awk '{$1=""; print}'
