.Nm
.Ar file ...
.Sh DESCRIPTION
The
1997-10-18 17:54:51 +04:00
.Nm
utility
deletes the relocation information and symbol table used by
assemblers, loaders and debuggers.
This significantly
decreases the size of the installed binaries and saves disk space.
.Pp
1997-10-18 17:54:51 +04:00
.Nm
is more aggressive about stripping unecessary information
than the GNU equivalent. The
GNU binutils
.Xr size 1
utility uses the "unecessary" information and may not be able to
find the size of executable segments of stripped files.
The strippped files are still correctly executed.
.Pp
1997-10-18 17:54:51 +04:00
.Nm
exits 0 on success and 1 if an error occurred.
