如何判断某个字符是另外一个字符的子串

121433107

请教一下;  有两列数据：
A  ：  0xb0000100100000005500ff01
B：  0xb0000100100000005500FF01FFFFFFFFFF

上述两列字符串，我需要判断如果A是B的子串，我就认为A和B相等，请教大神 ，shell脚本如何实现？？？
感谢

1. echo '0xb0000100100000005500FF01FFFFFFFFFF'|awk 'index(tolower($0),"0xb0000100100000005500ff01"){print "Y";exit}{print "N"}'

你好:
  感谢，有没有类似if else的比较，
if[] ;then
  // 相等的时候需要处理
else
  //不相等的时候也需要做处理
fi

in Bash shell

$ A="0xb0000100100000005500ff01"

$ B="0xb0000100100000005500FF01FFFFFFFFFF"

$ if [[ "$B" =~ "$A" ]]; then echo yes; else echo no; fi
no

$ shopt -s nocasematch

$ if [[ "$B" =~ "$A" ]]; then echo yes; else echo no; fi
yes

$ shopt -u nocasematch

$ if [[ "$B" =~ "$A" ]]; then echo yes; else echo no; fi
no
