NAME
mhpath - print full pathnames of MH messages and folders (only available within the message handling system, mh) SYNOPSIS
mhpath [+foldername] [msgs] [-help] OPTIONS
Prints a list of the valid options to this command. DESCRIPTION
Use the mhpath command to display the full pathname of the specified folder. If you do not specify a folder, mhpath displays the pathname of the current folder. If you specify a message with its message number, mhpath displays the pathname of the specified message. You can also specify a number of messages, or a range of messages. If the top of the range that you specify is greater than the last message in the folder, mhpath displays as much of the specified range as possible. Additionally mhpath can take a keyword or a sequence name. The following keywords are acceptable: The first message in the folder. The last message in the folder. The message after the last message in the folder. You cannot use new as part of a message range. The current message in the folder. The message before the current message. The message after the current message. All of the messages in the folder. PROFILE COMPONENTS
Path: To determine your Mail directory EXAMPLES
In the following example, mhpath displays message 3 in the folder +inbox: % mhpath +inbox 3 /r/phyl/Mail/inbox The following example dis- plays the pathname of messages 2 to 5 in the current folder: % mhpath 2-5 /r/phyl/Mail/inbox/2 /r/phyl/Mail/inbox/3 /r/phyl/Mail/inbox/4 /r/phyl/Mail/inbox/5 FILES
