which I believe is base64 encoded text from the mail.

I have made a script to search the ordinary text for som data,and extract it to a new file. The way I did this was to copy and paste the text from the mail when reading it in a mail client.

I have appx 6000 mails I want to search for data, but I don't want to deal with the text in the avove mentioned format (all the =20).

Anyone who have an idea how to convert this?

i've tried: cat "infile" | openssl enc -a -d > "outfile" without any luck.

Can I use a commandline mail client that runs from a script?

Would be very happy if one of you clever guys have an approach to this.

Best regards

Search for "mpack .rpm", then "munpack -C /temp/dir /path/and/mailbox/name" should do.
