python处理脚本参数
def handle_opt():global cluster_name, cluster_name_prefix, colo, decom_hostlist, decom_node
try:
opts, args = getopt.getopt(sys.argv, "hc:s:f:n:", ["help", "cluster=", "colo=", "file=", "hostname="])
except getopt.GetoptError as err:
usage()
sys.exit(wrong_parameter)
for op, value in opts:
if op in ("-c", "--cluster"):
cluster_name_prefix = str.lower(value)
print cluster_name_prefix
elif op in ("-f", "--file"):
decom_hostlist = str.lower(value)
print decom_hostlist
elif op in ("-n", "--hostname"):
decom_node = str.lower(value)
print decom_node
elif op in ("-s", "--colo"):
colo = str.lower(value)
print colo
elif op in ("-h", "--help"):
usage()
sys.exit(wrong_parameter)
cluster_name = cluster_name_prefix + "-" + colo
以上脚本命名为handle_opt.py
用法如下：
python handle_opt.py --cluster Hera --colo PHX --hostname $server_name
此脚本对参数大小写不敏感，同时参数支持短选项和长选项。
