Removing only the first 0:

Code:
awk '{sub(/^0/,"")}1' list

I presume you want to delete all the leading zeroes, not only the first one, right? This the solution in sed:

Code:
sed 's/^00*//' /path/to/sourcefile > /path/to/resultfile

It should be said that both the awk- and the sed-solution are easily changed to achieve the respective other conceivable goal.

I hope this helps.

using Perl:
Code:
perl -pi -e 's/^0+//' filename

Another one:

Code:
awk '{print int($0)}' file
