我有一个只有 1 行但有 2G 个字符的文本文件。
我需要在文件中找到一些东西，但是该行太长而无法在任何编辑器中打开 - 无论是在 Unix 上，还是如果我将其 ftp 到我的 PC...
是否有一种快速/简单的方法来插入换行符，例如每 120 个字符？

Fold命令这样做，所以如果你想在 120 之后换行。
fold -w120 fie > newfile

sed 's/\(.\{120\}\)/\1\n/g' file.txt
如果您需要创建一个新文件，则只需重定向输出：
sed 's/\(.\{120\}\)/\1\n/g' file.txt > new_file.txt
以每行 4 个字符为例
[fotanus@thing ~]$ cat test.txt

你可以试试这条线：
sed -r 's/.{120}/&\n/g' file
如果要将更改写回原始文件：
sed -ir 's/.{120}/&\n/g' file
例如：
文件有 100 s，每 12 个字符添加一个换行符：
kent$ cat file
ssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssss
kent$ sed -r 's/.{12}/&\n/g' file
ssssssssssss
ssssssssssss
ssssssssssss
ssssssssssss
ssssssssssss
ssssssssssss
ssssssssssss
ssssssssssss
ssss

如果您不介意创建另一个文件。bash用on测试了这个linux。这里 blah.out 是输入文件
while read -r -d '' -n 120 record; do echo $record; done<blah.out > blah2.out
