base64

python 的base64.decodestring方法做base64解码时报错。

bash 复制代码

Traceback (most recent call last):
File "/export/www/outofmemory.cn/controllers/user.py", line 136, in decryptPassword
encryptPwd = base64.b64decode(encryptPwd)
File "/usr/lib/python2.7/base64.py", line 76, in b64decode
raise TypeError(msg)
TypeError: Incorrect padding

python 复制代码

 def decode_base64(data):
            """Decode base64, padding being optional.
            :param data: Base64 data as an ASCII byte string
            :returns: The decoded byte string.
            """
            missing_padding = 4 - len(data) % 4
            if missing_padding:
                data += b'='* missing_padding
            return base64.decodestring(data)

awk、sed 命令

bash 复制代码

awk 'BEGIN{sum=0}{sum+=\$1}END{print sum}' test.txt
sed -F '\t' a.txt b.txt > test.txt
相同行合并并求和
awk 'BEGIN{FS=OFS="|"}{a[$2]+=$1;b[$2]=b[$2]$NF"/"}END{for(i in a)print  a,i,b}' file
