awk print the body of an email

[maddog21]

I have fetched a couple of emails and stored then in /fetch/mail/oracle.txt, the displayed content is

Date:
From:
Subject:
To:
Content-Type:
---body -----
---------
Date:
From:
Subject:
To:
Content-Type:
----body -----
------
Date:
From:

I want to retrieve the body only from the emails i fetched,the problem i am having is the body doesn't have a tag,

the output should be like
email-1
----body---
email-2
----body---

If you know for sure that the only lines that you do not need are these:
Date:
From:
Subject:
To:
Content-type:

you could simply use "grep -v"

e.g., grep -v "^Date:" oracle.txt | grep -v "^From:" ......[etc., etc.] > final-output.txt

The ^ means the beginning of a line.

Most emails have a header section followed by a blank line, followed by the body.

grep -v "^Date" /var/mail/oracle | grep -v "^From:" /var/mail/oracle | grep -v "^To:" /var/mail/oracle |grep -v "^Subject:" /var/mail/oracle > final-output.csv

i tried the above command but it displays everything instead of displaying the body only.

Sorry for the inconvenience, Thank you.

You can tell awk what is the start and end pattern .Something like below .


awk '/---body -----/,/------/{print}' email.txt

grep -v "^Date" /var/mail/oracle | grep -v "^From:" /var/mail/oracle | grep -v "^To:" /var/mail/oracle |grep -v "^Subject:" /var/mail/oracle > final-output.csv

I guess I should have been more explicit. You should not specify the file name after the first pipe.

grep -v some-pattern filename | grep -v another-pattern | grep -v yet-another-pattern > final-output

"-v" is to exclude. | is used to direct the output from the previous operation to the next command. So, you only need the filename in the first command, i.e., before the first |

If you are using grep , you can avoid using multiple pipes and save some keystrokes .Use extended features , see below


egrep -v "(some-pattern filename|another-pattern|yet-another-pattern)" filename > final-output
