in reply to variable inside a string inside back ticks

Hello phamalda,

there are better ways to grab dates and filenames (PS infact haukex was faster than me and shown you better ways), whithout shelling out..

Anyway i cannot confirm your issue: it works as expected; you must have some other errors 

echo blur > 20170730_195758.dat

# warning windows double quotes!

perl -e "my $today = '20170730'; print `ls 20170730*.dat`"

20170730_195758.dat
