shell中的单引号和双引号拼接简单使用

#!/bin/bash

t1='myt1'
t2='myt2'

#普通输出
echo '"'${t1}: {${t2}}: sss'"'
echo '**********************************************'
echo '"'{${t1}: {${t2}} sss: eee}'"'
echo '**********************************************'
echo '"'{${t1}: {${t2}}, sss: eee, ${t2}: ${t1}}'"'
echo '**********************************************'
echo -e '"'{${t1}: {${t2}},'\n'sss: eee,'\n'${t2}: ${t1}}'"'
echo '**********************************************'
echo ''$t1: $t2''
echo '**********************************************'
echo "$t1: $t2"
