I have a directory with a bunch of files and each file contains millions of emails.



I need to get all the emails that don't fit with this pattern 



 x.y@enron.com


x and y are letters.



I have this now but it doesn't match the correct emails



grep -P -r -x (?![a-z]*.[a-z]*@enron)



shell command-line grep regular-expression

  • Single quote your search pattern. Not only should this not match the correct emails, it should be throwing the following (or similar) error: -bash: ![a: event not found. You are trying to run nonsense commands in a subshell.

  • Your grep will need to be a lot more sophisticated to separate out each email from the various files in order to display only those emails that don't have the pattern, versus every line as you have it now.

Answer



grep -Evr "[a-z]+.[a-z]+@enron"


Explanation



-E - Use extended regex. (Allow some characters to be used without escaping them)



-v - Invert the matches. (Everything that doesn't match the pattern will be shown)



-r - Search files recursively.



[a-z]+.[a-z]+@enron - Your regex just with + instead of *, as I expect that there must be some letters in each section.

    This doesn't work at all. Maybe you were looking for grep -Evr? This will still show the body of the emails with the x.y@enron addresses though.

  • It still wont work though, please test it.

  • the -v is not my option. Now i notice that the files also contain the message that users wrote

    Thank you but that is not helping very much. My current regex catches that correctly. You mentioned messages in the content as well and that's why I asked you for the sample.

Postfix configuration issue with fips on centos 7; mailgun relay

Image
Clash Royale CLAN TAG #URR8PPP up vote 0 down vote favorite I am trying to setup postfix to relay all mail generated on the local machine via SMTP to a mailgun relay. I have used the mailgun relay before with success on an ubuntu server, but I am migrating to a Centos 7 server which I will be running in FIPS mode. There error log is below, slightly sanitized. I have a small enough network that I choose to have each machine reach out to mailgun individually (this the loopback-only, 127.0.0.0/8 restrictions) and no firewall open port allowing smtp in to the machine. I assume the FIPS mode (and with it disabling of MD5) is causing problems, but I don't know how to overcome it or if it is even possible for tls_fprint to use some supported hash such as sha256 or sha512. However, the relay=none is slightly concerning since I have relayhost set, but perhaps that is because the smtp process is failing? Any help would be appreciated! postconf -n: alias_database = hash:/etc/alia
