Assuming that the file memo is a non-empty text file containing:
Code:
1
3
5
6
4
2

and that there is no file named none, what output would you expect to get in the files named save1, save2, and letter if you were to run the pipeline:
Code:
cat memo none 2>save1 | sort - none 2>save2 > letter

? If you then actually run this pipeline with the input files set up as described above, did you get the output you expected? If not, what did you get and what did you expect to get?

NAME

       install-memo - installs a new memo in a Palm Computing Device

SYNOPSIS

       install-memo -p <port> [-c category ] filename [filename filename ...]

DESCRIPTION

       install-memo allows the user to write one or more files as a new memo or memos, respectively, onto the Palm handheld device.

   OPTIONS
       -p --port <port>,
	      Use  device  file port to communicate with the Palm handheld device. If this is not specified, will look for the $PILOTPORT environ-
	      ment variable. If both are not found, will fall back to /dev/pilot.

	      Display help synopsis for install-memo

       -v --version
	      Display version of install-memo

       -c category
	      Install memo(s) to category category by default. Normally install-memo uses Unfiled as the default category.

       -q     Causes install-memo to be quiet and not prompt you to press the HotSync button.

       -r     Replace all memos in the category specified by the -c category option.

       -t     Use the filename as the title for the memo. (The title is the first line of a memo.)

USAGE

       The program will connect to the Palm handheld device, and write the file or files given on the command line into the MemoPad application on
       the Palm.

KNOWN BUGS

       The Palm Device may have a maximum length on memo sizes.
