cc -c  -Wall -DHAVE_SEMUN -g globcr.c
cc -c  -Wall -DHAVE_SEMUN -g globget.c
cc -c  -Wall -DHAVE_SEMUN -g globlk.c
cc -c  -Wall -DHAVE_SEMUN -g globset.c
cc -c  -Wall -DHAVE_SEMUN -g globvar.c
cc -c  -Wall -DHAVE_SEMUN -g globdest.c
cc -c  -Wall -DHAVE_SEMUN -g globun.c
cc -o globvar globat.o globcr.o globget.o globlk.o globset.o  globvar.o globdest.o globun.o
$
					

The usage information display is available with the -h option:

$ ./globvar -h globvar [-i] [-s size] [-e] [-u] [-r] [-c] var... var=value... Options: -i Initialize new ...
