FOR MULTIPART MESSAGES, GIVE THE -part SWITCH. ## IF THE SCRIPT STORES PARTS THAT AREN'T LISTED IN ITS $profile ## VARIABLE (SEE BELOW), IT WARNS YOU. ## ## BECAUSE mhn -store UN-ENCODES THE MESSAGE, THIS IS AN EASY WAY ## TO UN-DO quoted-printable AND base64 ENCODING. mhnout=/tmp/MIMECATm$$ profile=/tmp/MIMECATp$$ stat=1 # DEFAULT EXIT STATUS; RESET TO 0 FOR NORMAL EXITS trap 'rm -f $mhnout $profile; exit $stat' 0 trap 'echo "$0: interrupted. Quitting early..." 1>&2; exit' 1 2 15 # THE MH 6.8.3 VERSION OF mhn -store SEEMS TO HAVE A BUG: # A mhn-store- PROFILE ENTRY OF "-" (DASH) IS SUPPOSED TO WRITE A # CONTENT TO STANDARD OUTPUT. BUT IT DOESN'T; IT MAKES A FILE # NAMED "-". WORK AROUND THE PROBLEM BY MAKING A PROFILE STRING # THAT RUNS "| cat". IF YOUR VERSION OF mhn WORKS RIGHT, REPLACE # THE LINE BELOW WITH output='-' AND CHANGE THE grep -v COMMAND. output='| cat' # CONFIGURE FOR TYPES YOU WANT TO BE ABLE TO OUTPUT. # TYPES NOT LISTED WILL BE STORED USING RULES IN YOUR OTHER PROFILE(S). # NOTE: SHELL EXPANDS SOME METACHARACTERS (LIKE ` AND $) IN HERE: cat > $profile << ENDPROFILE mhn-store-text/plain: $output mhn-store-text/enriched: $output mhn-store-text/richtext: $output mhn-store-application/octet-stream: $output mhn-store-application/postscript: $output ENDPROFILE # STORE PARTS IN $profile -- AND MAYBE OTHER PLACES TOO. CAPTURE mhn STDERR: MHN=$profile mhn -store -noverbose -noauto ${1+"$@"} 2>$mhnout # CHECK mhn OUTPUT FOR PROBLEMS. TYPICAL OUTPUT: # 1. storing msg 105 part 1.1 using command (cd /tmp; cat) # 2. storing message 105 part 2 as file /tmp/105.2.basic # # IF ANY LINES DON'T MATCH LINE 1 ABOVE, SHOW THEM. # ELSE SET A ZERO (SUCCESS) EXIT STATUS: grep -v "^storing m.*using command (cd.*cat)" $mhnout 1>&2 || stat=0
