The > operator is redirecting the output to file "id".
Converting => operator to a letter/word like "and" prints the output without printing the ID
I'm getting the result without any ID... This will give u a result sans id

perl -e "for (glob '*') { ($id) = /\d+$/ || /^\d+/; print \"$_\n\"; }"

You can also try this
UPDATED CODE(thanks to cdarke):

perl -e "while (<*>){print $_.\"\n\";}"
[download]

Same result
