试图让我的脚本更通用,所以我添加了一些标志。我的问题是,只有当您键入 -h 时,帮助才有效。我想在没有选择标志时调用 -h 。
例如:
python 0_log_cleaner.py
Traceback (most recent call last):
File "0_log_cleaner.py", line 51, in <module>
getFiles(options.path,options.org_phrase,options.new_phrase,options.org_AN,options.new_AN,options.dst_path)
File "0_log_cleaner.py", line 37, in getFiles
for filename in os.listdir(path):
TypeError: coercing to Unicode: need string or buffer, NoneType found
但如果我添加 -h 我会得到:
python 0_log_cleaner.py -h
用法:示例:
python 0_log_cleaner.py --sp original_logs/ --dp clean_logs/ --od CNAME --nd New_CNAME --oan 10208 --nan NewAN
Options:
-h, --help show this help message and exit
--sp=PATH Path to the source logs ie original_logs/
--dp=DST_PATH Path to where sanitized logs will be written to ie
clean_logs
--od=ORG_PHRASE original domain name ie www.clientName.com, use the command
-od clientName
--nd=NEW_PHRASE domain name to replace -od. ie -od clientName -nd domain
makes all log that use to be www.clientName.com into
www.domain.com
--oan=ORG_AN original AN number
--nan=NEW_AN AN number to replace original. ie -oan 12345 -nan AAAA1
replaces all instances of the AN number 12345 with AAAA1
