[Unix] Maildir, mutt and vim

I'm a huge fan of mutt mail reader and Maildir.

My mutt spawn vim in console, and I can chat with anyone as fast, as in any faddish messenger.

Maildir is cool.

The following bash script I use to print info about new emails in Maildir (From and Subject):

if [ ! -z "$(ls -A ~/Maildir/new/)" ]; then
    cat ~/Maildir/new/* | grep "^\(From\|Subject\):"

(Adjust it to your folders.)

This script prints new email counts in each Maildir folder:

cd ~/Maildir
find . -name new | sort |
while read LINE;
        files=$(find "$LINE" -type f -name '*' -print | wc -l)
        if [ "$files" != "0" ]; then
                echo $LINE - $files | sed 's/\/new//g'

Sample result:

./.Archives - 4
./.mail-lists - 2
./notifications - 1
./.SPAM - 8
./.Trash - 105

Now about mailing lists I'm subscribed to. Can I see a statistics, what today's trends are?

 % cd ~/Maildir/.mail-lists/cur

 % cat * | grep "^Subj"  | sort | uniq -c | sort -n

Can you do this in your favorite email client? Or maybe google mail, god forbid me?

I also use mairix as a search engine for my Maildir emails. (The only issue with it is that it can't handle utf-8.)

I probably should upgrade to mu

Anyway, call this Python script from mutt ('|' (Pipe to command), then type ./search.py). The 'From' field of the email message you're currently at will be passed to the script:

#!/usr/bin/env python3

import fileinput, os

for line in fileinput.input():
    if line.startswith ("From:"):
        if s[0]=='<' and s[-1]=='>':
        print (s)
        os.system ("mairix -f ~/mail/.mairixrc tf:" + s)

print ("Error, can't parse this: ",line)

Depending on mairix's config file, all your correspondence with that email will be gathered in 'Search' folder, which can be browsed in mutt.
