意外字符fi附近的语法错误

Question

我正在测试我的Linux发行版上安装的各种东西的版本，但是我一直收到此错误

cat > version-check.sh << "EOF"
#!/bin/bash
# Simple script to list version numbers of critical development tools
export LC_ALL=C
bash --version | head -n1 | cut -d" " -f2-4
MYSH=$(readlink -f /bin/sh)
echo "/bin/sh -> $MYSH"
echo $MYSH | grep -q bash || echo "ERROR: /bin/sh does not point to bash"
unset MYSH
echo -n "Binutils: "; ld --version | head -n1 | cut -d" " -f3-
bison --version | head -n1
if [ -h /usr/bin/yacc ]; then
 echo "/usr/bin/yacc -> `readlink -f /usr/bin/yacc`";
elif [ -x /usr/bin/yacc ]; then
 echo yacc is `/usr/bin/yacc --version | head -n1`
else
 echo "yacc not found"
fi
EOF

在此文件末尾，我收到语法错误。

感谢您的帮助
