我有一个从命令行传递的字符串变量,我想在 SSH 中使用它。
#!/bin/bash
while getopts ":b:e:" arg; do
case "${arg}" in
b) b="$OPTARG";;
e) e="$OPTARG";;
esac
done
echo "locally using $b and $e"
ssh @myhost "$b $e" << 'EOF'
echo "Remotely using $b and $e"
EOF
输出:
locally using 06-30-20-18-10 and 06-30-20-23-59
Bad escape character '06-30-20-23-59'
运行:bash file.sh -b 06-30-20-18-10 -e 06-30-20-23-59
如何避免错误的转义字符并远程使用变量?
