git diff

First of all, as a basic concept of git diff, the basic behavior of “git diff” is “display of changes made in the working tree”.

Then, if you do not specify the comparison source, you can specify “comparison source” as an argument, but by default, the difference when compared with “index” →　”working tree” with “index” as the comparison source and it will display.

HDML??

Markup language for creating content for mobile information terminal. It is used in EZweb which can be used with au’s mobile phone. One page is handled as “card” and a group of multiple cards is called “deck”. Data is transmitted and received on a deck basis. It is not compatible with Compact HTML which is a description language for the same portable information terminal.

What is an escape sequence (escape character)?

An escape sequence is a special character string that controls character output, such as character color change, cursor movement, and character deletion, when outputting characters on the screen, rather than outputting the characters themselves.

In addition to the information that people can recognize as “character”, information other than “characters” such as control characters and character editing information on the OS is also included a s character information used in the OS. These characters are sometimes called “special characters”. An escape sequence exists for this special character to let people enter characters and tell it to the OS.

Typical escape sequences include the following characters.

\a : bell character(alert)
\b : return one character
\f : page feed(clear)
\n : line feed, return
\r : back to the beginning of the same line
\t : horizontal tab
\v : vertical tab
\\ : show \
\' : single quotation mark
\" : double quotation mark
\0 : null

unix permission “r w x”

Permissions are represented by nine-character strings such as rwxr-xr-x and numeric values such as 755. The 9 character string consists of r(readable), w(writable), x(executable), and hyphen(-), which have the meanings.

The commonly used permission patterns are as follows.
644
normal HTML file etc. can read and write, but group members and others can only read.

666
files to be written by CGI script, etc. Both myself and group members and others can read and write.

755
Regular directories, commands, CGI script, etc. Everyone can read and execute, but write only oneself.

777
Directory for CGI scripts to create files. Anyone can do anything. Slightly dangerous on security.

In a sense this is already fine, but i want to it center.

#content {
	margin-top:100px;
	text-align:center;
}
#content h1{
	font-size: 16px;
	margin-bottom:40px;
}

well, finally reaching the point.
