- Well I just built PL20 and I continually get the following when trying
- to print messages from elm:
-
- readmsg: illegal option -- I
-
- followed by the print job spooled message.
-
- I see -I is an undocumented feature...
-
- From readmsg.c
-
- The undocumented "-I" option is a kludge to deal with an Elm race
- condition. The problem is that Elm does piping/printing/etc. by
- running "readmsg|command" and placing the mail message selection
- into a folder state file. However, if the "command" portion of
- the pipeline craps out, Elm might regain control before "readmsg"
- completes. The first thing Elm does is unlink the folder state
- file. Thus "readmsg" can't figure out what to do -- there is no
- state file or command line args to select a message. In this
- case, "readmsg" normally gives a usage diagnostic message. The
- "-I" option says to ignore this condition and silently terminate.
-
-
- Any suggestions...
