SHELL传参注意事项,尽量使用双引号传参

#!/bin/bash function convert(){ keyword=${1//\\/\\\\\\\\}
        keyword=${keyword//\./\\.}
        keyword=${keyword//\*/\\\\*}
        keyword=${keyword//\&/\\\\&}
        keyword=${keyword//\$/\\\\$}
        keyword=${keyword//\+/\\\\+}
        keyword=${keyword//\=/\\\\=}
        keyword=${keyword//\^/\\\\^}
        keyword=${keyword//\%/\\\\%}
        keyword=${keyword//\!/\\\\!}
        keyword=${keyword//\@/\\\\@}
        keyword=${keyword//\#/\\\\#}
        keyword=${keyword//\[/\\\\[}
        keyword=${keyword//\]/\\\\]}
        keyword=${keyword//\-/\\\\-}
        keyword=${keyword//\ /\\ }
#       keyword=${keyword//\?/\\\\?} ?号不能转义.要不然替换不成功
        keyword=${keyword//\"/\\\"}
        echo $keyword } #调用函数,如果传参有空格,必须加双引号,否则函数会认为是多个参数 repkey=$(convert "$2") repkey1=$(convert "$2") newkey=$(convert "$3")

#调用shell脚本
sh xxx.sh /root "rep1" "rep2" "hh" 0
