How to reflect changes after editing the contents of crontab file directly. There is no need to restart cron after changing crontab.
On Linux, it checks the modification time of cron every minute and reloads if there is a change, so change of the file of cront if you do, your changes will take effect immediately without having restart cron.

ps: Check the processes currently running on Linux
a: display the process of terminal operation
f(option -h, option-forest): display processes in a hierarchy
e: display the command name and environment, variables being executed.

“Hostname” is a command to display the host name of the system. If you are the root user(superuser), you can also change the host name.
[vagrant@localhost ~]$ hostname
localhost.localdomain
[vagrant@localhost ~]$ sudo -S “hostname”
localhost.localdomain
sudo yum -y install perl-CGIで、perl-CGIをinstall
[vagrant@localhost ~]$ sudo yum -y install perl-CGI

データがcgiに届きました。

うーん、パラメータが付くのが気になるな。。hiddenだと、type=”password”にできないし、困ったな。。

なんでやねん、て、use CGIをコメントアウトするとinternal server errorが消えているので、おそらくcuse CGIがinstallされていないだけかと。。
[vagrant@localhost ~]$ find `perl -e ‘print “@INC”‘` -name ‘*.pm’ -print | grep CGI
<!DOCTYPE html>
<meta charset="utf-8">
<style>
#errorMessage {
color: red;
}
</style>
<form>
<div id="errorMessage"></div>
<label for="name">お名前:</label>
<input name="name" id="name" required><br>
<label for="password">パスワード:</label>
<input type="password" name="password" id="password" required><br>
<label for="passwordConfirm">パスワード(確認):</label>
<input type="password" name="confirm" id="confirm" oninput="CheckPassword(this)"><br>
<input type="submit" value="送信">
</form>
<script>
function CheckPassword(confirm){
var input1 = password.value;
var input2 = confirm.value;
if (input1 != input2){
confirm.setCustomValidity("入力値が一致しません");
} else{
confirm.setCustomValidity('');

うまくいきました。
oninput=””か、なるほど。

<script>
var form = document.forms[0];
form.onsubmit = function(){
form.password.setCustomValidity("");
if(form.password.value != form.passwordConfirm.value){
form.password.setCustomValidity("パスワードと確認用パスワードが一致しません")
}
}
form.addEventListener("invalid", function(){
document.getElementById("errorMessage").innerHTML = "入力値にエラーがあります";
}, false);
</script>
あれ？ あれ？
うまくいきませんね。。
I want to display the “confirmation”, “clear” and “return” buttons within HTML form.
Here is User Interface.
confirm: type=”submit”
clear: type=”reset”
return: type=”button” onclick=”history.back()”
<center> <button type="submit">確認</button> <button type="reset">クリア</button> <button type="button" onclick="history.back()">戻る</button> </center>
It’s easy than expected.

TravisCI flow
1. git clone the repository(where .travis.yml is located) from Github
the option –depth=50 is attached to git clone
2. Move to the cloned repository
3. Get committed code by git checkout
Environment variables written in .travis.yml apply here
4. If you use cache, get cache
5. Specify the version of Ruby to use
6. The one defined in before_install is executed
if you use a cache, it will be added here
7. The one defined in install is executed
8. The one defined in before_script is executed
9. What is defined in script is executed
If the exit code is 0 it is judged as success, otherwise it is judged as failure
10. The one defined in after_success or after_failure is executed.
11. The one defined in after_script is executed
