我正在运行以下一段bash代码：
cat << END_TEXT
_ _
| | | |
__ _| |__ ___ __| |
/ _` | '_ \ / __/ _` |
| (_| | |_) | (_| (_| |
\__,_|_.__/ \___\__,_|
END_TEXT
并收到一个错误：
bash: command substitution: line 1: Syntax error near unexpected token `|' bash: command substitution: line 1: ` | '_ \ / __/ _'
无需逃避反击.只需使用引用的here-doc字符串：

_ _
| | | |
__ _| |__ ___ __| |
/ _` | '_ \ / __/ _` |
| (_| | |_) | (_| (_| |
\__,_|
END_TEXT
按照男人的说法：
If word is unquoted,all lines of the here-document are subjected to parameter expansion,command substitution,and arithmetic expansion,the character sequence
\<newline>is ignored,and\must be used to quote the characters\,$,and`.
