# fmt命令用法

`fmt`负责填充并连接文本行，生成长度不超过指定字符数（默认为 75）的输出行。
```sh
$ cat push.sh
#!/bin/bash
TIMESTAMP=$(date +%s)

rm -rf resources/ public/ .hugo_build.lock
git add .
git commit -m "update: ${TIMESTAMP}"
git push
sleep 3s
echo "Done! Commit${TIMESTAMP}"
sleep 3s

$ fmt push.sh
 rm -rf resources/ public/
 git commit -m "update: ${TIMESTAMP}"
 sleep 3sne! Commit${TIMESTAMP}"
```
`fmt`常用选项如下:

`-c`
`--crown-margin`
悬挂缩进（crown margin）模式：保留段落中前两行的缩进，并将后续每一行的左边界与第二行的左边界对齐。

`-t`
`--tagged-paragraph`
标记段落（tagged paragraph）模式：类似于悬挂缩进模式，但如果段落第一行的缩进与第二行相同，则将第一行视为单行段落。

`-s`
`--split-only`
仅拆分行。不合并短行以形成长行。这可以防止代码示例及其他此类“已格式化”文本被不适当地合并。

`-u`
`--uniform-spacing`
统一间距。将单词间的间距缩减为一个空格，句子间的间距缩减为两个空格。

`-width`
`-w width`
`--width=width`
将输出行填充至 width 个字符的宽度（默认值为 75，或者若提供了 goal 参数，则为 goal 加上 10）。

`-g goal`
`--goal=goal`
fmt 最初尝试使行宽达到 goal 个字符。默认情况下，该值比 width 小 7%。

`-p prefix`
`--prefix=prefix`
仅对以 prefix 开头的行（其前可带有空白字符）进行格式化。在格式化过程中，会移除前缀及前面的空白字符，随后将其重新附加到每个格式化后的输出行上。此选项的一种用途是格式化特定类型的程序注释，同时保持代码不变。
