I got a file output from my perl script.
我从perl脚本获得了一个文件输出。
When I use less to open it less output it looks like this: ABCDEFG^\HIJKLMN
当我使用少打开它输出看起来是这样的:英语字母^ \ HIJKLMN
When I use cat or head to open it head output it looks like this ABCDEFGHIJKLMN
当我使用cat或head打开它的head输出它看起来像这个ABCDEFGHIJKLMN
So I want to ask what is the ^\ symbol?
所以我想问^ \符号是什么?

This representation is known as "caret notation" and is one notation used by some tools and editors to show undrawable control characters.
这种表示法称为“插入符号”，是一些工具和编辑器用来显示不可画控制字符的一种表示法。
^\ in particular represents the ASCII file separator character, aka "FS" or 0x1C.
^ \特别是表示ASCII文件分隔符,又名“FS”或0 x1c。
You can determine this manually by taking the ASCII value of the backslash (0x5C) and substracting 0x40, giving 0x1C. Should you want to input it in a terminal, you can press Ctrl+\.
您可以通过提取反斜杠(0x5C)的ASCII值并对0x40进行分段，得到0x1C，来手动确定这一点。如果要在终端中输入，可以按Ctrl+\。
This character is not used in any meaningful sense today. How it got into your perl script output is anyone's guess.
这个字在今天没有任何意义。任何人都在猜测它是如何进入perl脚本输出的。
