I can't think of a non-ugly way to do this. A semi-ugly ;-) way is: - Get a list of messages from "mhpath all" or "mhpath cur:-N cur:N" - Strip off the path, leave the number - Use grep -CN to get N lines of context around the current message number. Use start- and end-of-line anchors (^ and $) to be sure you don't match any other messages. For example, if you want up to 5 messages surrounding message 4363: $ mhpath 4363:-5 4363:5 | sed '[EMAIL PROTECTED]/@@' | grep -C5 "^4363\$" 4359 4360 4361 4362 4363 4364 4365 The last message in the folder is 4365.
