# fold命令用法
`fold` 将文件内容自动断开长行。默认情况下，fold 会折断超过 80 列的行。输出会根据需要分成多行。

`-w number`设置具体列数，默认为80
```sh
$ fold -w 30 push.sh
#!/bin/bash
TIMESTAMP=$(date +%s)

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

`-b`按字节计数而不是列计数，这样制表符、退格符和回车符每个都算作占用一列，就像其他字符一样。

`-c`按字符数而不是列数来计数，这意味着包含宽于一列字符的行在视觉上会更长。

`-s`在单词边界换行：在最大行长度之前最后一个空格处换行。如果该行没有这样的空格，则像平常一样在最大行长度处换行。
