Take a look at RFC 1342: https://tools.ietf.org/html/rfc1342 From that: - An "encoded-word" is a sequence of printable ASCII characters that begins with "=?", ends with "?=", and has two "?"s in between. - Not sure if you just want to toss these away or what. But you might want to possibly try something like this: #!/bin/bash $file = "/your_subject.txt" # if RFC1341 discard if [ ! `grep -q '^Subject: =?' mailfile` ] then grep '^Subject: >> $file fi Kevin On Sun, 23 Jun 2019, Michael Christopher Robinson wrote: On Sun, 2019-06-23 at 17:54 -0500, Michael Christopher Robinson wrote: I am having trouble using grep to grab subject lines from my spam folder on eskimo.

Michael, Attachments are ripped off messages to this mail list. Regardless, have you considered using awk rather than grep? You can set /^Subject:/ as the pattern and the action will print the result to a specified file. Regards, Rich ___ PLUG mailing list PLUG@pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug
