在bash中输入时

如何找到这27个类似的命令？

最大限制为15，您可以按以下方式临时更改此命令

...
 #if len(possible_alternatives) > max_len:
 #    print(_("No command '%s' found, but there are %s similar ones") % (word, len(possible_alternatives)), file=sys.stderr)
 #elif len(possible_alternatives) > 0:
 if len(possible_alternatives) > 0:
            print(_("No command '%s' found, did you mean:") % word, file=sys.stderr)
            for (w, p, c) in possible_alternatives:
                print(_(" Command '%s' from package '%s' (%s)") % (w, p, c), file=sys.stderr)
...

find CommandNotFound.py

sudo find / -name "CommandNotFound.py"

以root权限打开此文件

sudo gedit /usr/lib/python3/dist-packages/CommandNotFound/CommandNotFound.py

将最大长度15更改为150

def print_spelling_suggestion(self, word, min_len=3, max_len=150): 

或变更如下

...
 #if len(possible_alternatives) > max_len:
 #    print(_("No command '%s' found, but there are %s similar ones") % (word, len(possible_alternatives)), file=sys.stderr)
 #elif len(possible_alternatives) > 0:
 if len(possible_alternatives) > 0:
            print(_("No command '%s' found, did you mean:") % word, file=sys.stderr)
            for (w, p, c) in possible_alternatives:
                print(_(" Command '%s' from package '%s' (%s)") % (w, p, c), file=sys.stderr)
...

试验

@sat看起来一点都不相关。基于编辑距离，通常用于拼写检查。这是一个很好的答案。非常感谢。
