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
L*
There are no rules, there are no thumbs..
