问题 We are trying to decode some uuencoded PDF files that are embedded in a txt file. The problem we have is that most of the PDF files decoded just fine using Python's uuencode library. Here is the code: try: decoded_file,m=uudecode(fileString) except: decoded_file='' However, some of the files cannot be opened after they are decoded. We receive the message "There was an error opening this document. The file is damaged and could not be repaired." The only thing we could find on Google is that

问题 I have a script that currently does: cat $body | uuencode $attachment $attachment | sendmail $sender -t What should I adjust so that $attachment could be multiple attachments? I have come up with the below but it doesn't look correct? cat $body | for i in $attachments do uuencode $i $i done | sendmail $sender -t 回答1: Typically, you don't want to store a list of file names in a parameter. With default IFS , spaces embedded within file names will give rise to problems. Instead, declare an array

问题 I was writing a Java program to download attachments from POP3 email. Originally I do this with getting an input stream of a MimePart if its content type is validated. And then I can simply write the input stream into a local file through a FileOutputStream. However, one thing I encountered is that, after I received an email with an attached file as its only content and access it, the mail (of type Message) only consists of a single part, which is of type text/plain. And its content consists

问题 I am processing many text files which (some of them) contain uuencoding which can be .jpg or .pdf or .zip of .xlsx etc. I don't care about the embedded UUencoded data, so I would just like to discard these passages and keep the rest of the text. I'm struggling with how to come up with a method to skip only just enough, but not too much. To summarize http://en.wikipedia.org/wiki/Uuencoding each blob begins with begin 644 filename.extension every line after the begin 644 seems to start by the

How to base64 encode /dev/random or /dev/urandom?

阅读更多关于 How to base64 encode /dev/random or /dev/urandom?

cat /dev/urandom is always a fun way to create scrolling characters on your display, but produces too many non-printable characters. Is there an easy way to encode it on the command-line in such a way that all of its output are readable characters, base64 or uuencode for example. Note that I prefer solutions that require no additional files to be created. What about something like cat /dev/urandom | base64 Which gives (lots of) stuff like hX6VYoTG6n+suzKhPl35rI+Bsef8FwVKDYlzEJ2i5HLKa38SLLrE9bW9jViSR1PJGsDmNOEgWu+6 HdYm9SsRDcvDlZAdMXAiHBmq6BZXnj0w87YbdMnB0e2fyUY6ZkiHw+A0oNWCnJLME9/6vJUGsnPL
