找到打印的匹配项

Question

我有以下bash脚本：

#!/bin/bash

#read user input and save to package variable
PACKAGE=${1}

#put variable value in double quotes and add .sty extension.
 echo "Searching..."
 SEARCH=$(tlmgr search --global --file \"$PACKAGE.sty\"
 regex="[a-z]+\:"

  if [[ $SEARCH =~ $regex ]]; then
  echo #code that prints matches here
  fi

我想回显与grep相同的匹配项，而不是像“找到的匹配项”那样显示常规消息。
