我有
\title{A64L(3)}
somethings
\textbf{a64l}()
\title{MALLOC(3)}
somethings
\textbf{malloc}()
我想
\title{\hypertarget{a64l}{A64L(3)}}
somethings
\textbf{\hyperlink{a64l}{a64l}}()
\title{\hypertarget{malloc}{MALLOC(3)}}
somethings
\textbf{\hyperlink{malloc}{malloc}}()
或者
\title{\hypertarget{a64l}{A64L}(3)}
somethings
\textbf{\hyperlink{a64l}{a64l}}()
\title{\hypertarget{malloc}{MALLOC}(3)}
somethings
\textbf{\hyperlink{malloc}{malloc}}()
这些是示例文件。可以有任何东西来代替A64Land MALLOC，但遵循模式（例如\title{new_word}）。
我必须这样做才能获得描述的功能https://tex.stackexchange.com/questions/407884/how-to-make-a-title-as-link-target
我更喜欢vim, sed, awk.

These functions provide a conversion between 32-bit long integers and
little-endian base-64 ASCII strings (of length zero to six). If the
string used as argument for \textbf{a64l}() has length greater than six,
only the first six bytes are used. If the type \emph{long} has more than
32 bits, then \textbf{l64a}() uses only the low order 32 bits of
\emph{value}, and \textbf{a64l}() sign-extends its 32-bit result.
The 64 digits in the base-64 system are:
\begin{verbatim}
'.' represents a 0
'/' represents a 1
0-9 represent 2-11
A-Z represent 12-37
a-z represent 38-63
\end{verbatim}
So 123 = 59*64\^{}0 + 1*64\^{}1 = ``v/''.

The value returned by \textbf{l64a}() may be a pointer to a static
buffer, possibly overwritten by later calls.
The behavior of \textbf{l64a}() is undefined when \emph{value} is
negative. If \emph{value} is zero, it returns an empty string.
These functions are broken in glibc before 2.2.5 (puts most significant
digit first).

编辑
由于没有答案完全符合要求，因此我对问题进行了更改。这种变化也给了我相同的结果，但方式不同。
主要是，我想将所有粗体文本与同一个单词的标题链接起来。
例如，在我得到的地方，\textbf{malloc}我想与\title{MALLOC(3)}和\textbf{a64l}建立链接\title{A64L(3)}。
现在，我制作了一个index包含标题词的文件。
文件索引
MALLOC(3)
A64L(3)
或者
MALLOC
A64L
或者
malloc
a64l
我想使用index文件修改主文件比以前的方法更容易。
伪代码
while read word
do
l_word=${word,,}
echo $l_word
sed -e 's/\\title{$word\(3\)}/\\title{\\hypertarget{$word}{$word\(3\)}}/' -e 's/\\textbf{$l_word}/\\textbf{\\hyperlink{$word}{$l_word}}/' inputfile > output.tex
done < index
[这段代码有一些错误，我无法检测到]
我想下面的作品请检查和更新。经过对一些数据的测试，它对我有用
虽然，这是可行的，但它可以在没有我无法制作的正则表达式的索引文件的情况下完成。
