Remove lines ending with a certain character

I have a file of a content like this:

Code:
abc_bla -def 800
abc_bla -def 802
abc_bla -def 804
abc_bla -def 806
abc_bla -def 808
abc_bla -def 810
abc_bla -def 812
abc_bla -def 814
...
abc_bla -def 898
abc_bla -def 900
abc_bla -def 902
abc_bla -def 904
...
abc_bla -def 990
abc_bla -def 992
abc_bla -def 994
abc_bla -def 996
abc_bla -def 998
abc_bla -def 1000
abc_bla -def 1002
abc_bla -def 1004
abc_bla -def 1006
...
...
abc_bla -def 1800

I would like to delete all lines in a file that end with a 0 (zero).

I tried this:

Code:
sed '/0/d' file

but this deletes all the lines containing a zero, and I want to delete only those *ending* with a zero.
Then I tried

Code:
grep '0$' file

but that gives me as output only the last line.

How can I select that it chooses the pattern when it is *only* at the end of the line?
So I want my output to be all the lines not ending with a 0.

NAME
gendef - DLL export extractor SYNOPSIS
gendef [options] <DLL> DESCRIPTION
gendef dumps DLL export information from 32- and 64-bit Windows executables (respectively PE32 and PE32+ executables). OPTIONS
- Dump to stdout -h, --help Briefly describe the syntax and options. -a, --assume-stdcall Assume functions with ambiguous calling conventions use stdcall. -I, --include-def-path <path> Add additional search paths in which to look for hint .def files. -f, --no-forward-output Don't output forwarders. OUTPUT
By default gendef writes the DLL export information to a file named after the DLL, replacing .dll with .def. KNOWN ISSUES
For 32-bit DLLs, gendef cannot detect if a function with no return value (void) exported by a DLL uses stdcall or cdecl. Two workarounds are available: either use the "-a" option to force stdcall calling conventions, or generate .def files for any DLLs the DLL you're inter- ested in depends upon. gendef will read other .def files found in the working directory to determine the calling convention in use. 64-bit DLLs are not affected, since they only use a single calling convention. SEE ALSO
genidl(1) AUTHORS
gendef was written by Kai Tietz and Jonathan Yong of the MinGW-w64 project. This manual page was written by Stephen Kitt <steve@sk2.org>, based on information provided with the program and in the project's wiki, for the Debian GNU/Linux system (but may be used by others). gendef Oct 6, 2011 gendef(1)
