shell 参数使用

关于shell中使用参数的两个例子：

 1 while getopts :s:o:ghe OPTION
 2 do
 3     case $OPTION in
 4     s)
 5         snp=$OPTARG
 6         echo "snp=$snp"
 7         ;;
 8     o)
 9         outdir=$OPTARG
10         echo "outdir=$outdir"
11         ;;
12     g)
13         if=1
14         echo "we will get hg18"
15         ;;
16     h)
17         chunhe=1
18         echo "use hom"
19         ;;
20     e)
21         zahe=1
22         echo "use het"
23         ;;
24     ?)
25         echo "usage:$0 -s \$snp_file -o \$outdir (-g:if u need hg18) (-h:out_for_hom) (-e:out_for_het)"
26         ;;
27 esac
28 done
29 
30 shift $((OPTIND-1))
31 echo "other = $@"
