$ [ -f TiOn.txt ] && { echo a; echo b; }
[ -f TiOn.txt ] && { echo a; echo b; }
+ '[' -f TiOn.txt ']'
+ echo a
a
+ echo b
b

Note the difference in syntax:

'(echo $pwd_base; echo $pwd; echo *)'
'{ echo $pwd_base; echo $pwd; echo *;}'

list is executed in the current (that is, parent) shell. The { must be followed by a space, and } must be lead by a ';'

$ [ -f TiOn.txt ] && { echo a; echo b }
[ -f TiOn.txt ] && { echo a; echo b }
>

— need the ';' at the end!

$ [ -f TiOn.txt ] && { echo a; echo b;}
[ -f TiOn.txt ] && { echo a; echo b;}
+ '[' -f TiOn.txt ']'
+ echo a
a
+ echo b
b

— the ending space in not important.
