Assign command (with pipe) output to a variable
Hi ,
I would like to assign command (with pipe) output to a variable. The code is as follows. The goal of the code is to get the last folder folder with a particular name pattern.
myDate=`ls | grep 2009 | tail -1`
echo "myDate=" $myDate
However, in the presence of the pipe, the code doesn't work.
I appreciate any suggestions.
Thanks
Jeff

mhpath(1) General Commands Manual mhpath(1)
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

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
