我有一个需要匹配的域名与正则表达式的一部分,并重定向到一个不同的域名与匹配的部分是文件名的一部分。
例如,在this-is.com上的htaccess中:
this-is-a-test.com redirects to this-is.com/test.htm
this-is-a-fish.com redirects to this-is.com/fish.htm
this-is-a-duck.com redirect to this-is.com/duck.htm
到目前为止,我已经尝试了以下几种方法:
RewriteEngine on
RewriteCond %{HTTP_HOST} ^t
我有下面的示例文件,并希望删除域名后的所有内容,并将第2列替换为4。
样本文件
one two three www.four.com
abc def ghi www.jkl.com
lion zebra eagle www.fish.com/sardines/shop
house building room https://www.kitchen.co.uk/something/or/other
plane car motorbike http://www.sheep.org/my/farm/yard/
最终的结果应该是:
one www.four.com three www.four.com
我用鱼作为我的登录终端。我在试着运行android模拟器。我已经编辑了bash配置文件,所以我通过输入bash切换到bash。我在注销计算机后重新启动我的终端,每当我输入任何内容时,都会出现错误。
命令: cd桌面/
响应:

因此,我有一个dataframe "fish8“,我尝试编写一个函数,该函数为dataframe的三个列(BIN、收集器、country)排除所有空行。问题是,代码不是在函数内部运行,而是在函数之外运行。我在脚本中还有很多类似的功能,它们都能工作,为什么这个不能工作呢?
#so it doesn't work when I run it like this
remove_empties=function(fish8){
fish8<<-fish8[!(fish8$BIN == "" | is.na(fish8$BIN)), ]

当我今天开始我的鱼壳时,我得到了以下错误: fish: Unknown command: pyenv

给定以下字符串:
mystring <- "one fish two fish red fish blue fish"
下面的函数允许替换其中一个单词的第n次出现:

word,"\\b"), n-1)

问题:
⚙ ~ fish --version

我已经在mac上使用鱼壳几个月了,没有问题。突然,当我打开终端时,会收到以下错误消息:

我分析了一组代码: corpus = ['rabbit rabbit fish fish fish fish fish',
'turtle rabbit fish fish fish fish fish',
'raccoon raccoon raccoon fish fish fish fish fish'] 对于TF*IDF计算,我运行如下代码: vectorizer = TfidfVectorizer()
vectors = vectorizer.fit_transform(corpus)
feature_names = vectoriz
假设您有以下字符串:
cat dog fish dog fish cat
您希望将所有cats替换为dogs,将所有dogs替换为fish,将所有fish替换为cats。从直觉上看,预期结果:
dog fish cat fish cat dog
如果您尝试了显而易见的解决方案,即循环使用replaceAll(),您将得到:
(原件) cat dog fish dog fish cat
(猫->犬) dog dog fish dog fish dog
(狗->鱼) fish fish fish fish fish fish
( ->猫) cat cat cat
我正在尝试将一个对象转换为一个类实例。当然,类实例的对象应该继承所有方法。
下面是我在示例代码(2)中的问题,因为我无法确切地解释我的意思:
Class Fish {}
Class Dog {}
class Instances() {
private Fish fish = new Fish();
private Dog dog = new Dog();
public Object getInstance(String className) {
if( className.equals("fish") )
我在雪佛兰终点站玩鱼和鱼。在我试图通过在我的fish_vi_key_bindings中设置config.fish来打开VI键绑定之前,它一直工作得很好。
它不起作用。显然,这只从版本2.2.x开始工作,而在cygwin上,我正在运行版本2.1.1。好吧没问题..。让我们从config.fish中删除该行,从而禁用它。当前,该文件如下所示:
# Path to your oh-my-fish.
set fish_path $HOME/.oh-my-fish
# Path to your custom folder (default path is ~/.oh-my-fish/custom)

我在Mac上使用brew安装了fzf ()。前几天我用啤酒把它取走了。
现在,每当我打开鱼壳时,我都会收到以下消息:

我想按属性对ArrayList进行排序。这是我的代码。
public class FishDB{
public static Object Fish;
public ArrayList<Fish> list = new ArrayList<Fish>();
public class Fish{

String LatinName;
//etc.
public Vis (String name) {
系统更新后,我的fish shell提示符就不再工作了。每当我打开终端时,都会看到以下错误:

我正在尝试通过~/.config/fish/config.fish命令设置我的鱼壳配置文件。我没有config.fish文件,安装后必须创建自己的文件。
我想更新这个配置文件的主要原因是显示我当前在终端中的GitHub位置。我在网上发现了以下设置:
set -g -x fish_greeting ''
# fish git prompt
set __fish_git_prompt_showdirtystate 'yes'
set __fish_git_prompt_showstashstate 'yes'
set __fish_git_promp
在这个类中,我正在创建一个catchFish方法,它基本上从池中返回一个随机的鱼,鱼应该从池中移除并从方法中返回,如果没有鱼,那么将返回null
这是我的密码
import java.util.Random;
public class Pond {
private int MAX_FISH = 10;
private Fish[] fish = new Fish[MAX_FISH];
private int numFish;
public Pond (int numFish, Fish[] fish) {

该命令在fish终端中运行良好:
source ~/.config/fish/config.fish
这是config.fish中一个相关的fish函数
function sf
