Script que j'utilise avec Thunderbird et Opera

Opera utilise la ligne de commande suivante :
thunderbirdmail mailto:[%t]?cc=[%c]&subject=[%s]&body=[%b]

Et thunderbirdmail correspond au script suivant (trouvé je ne sais plus où) :

#!/bin/sh
## Variables
THUNDERBIRD="/usr/bin/thunderbird"
PARAM="";

# Check if command line arguments have the form "mailto:somebody@somewhere.com?subject=something"
# if that's true put "somebody@somewhere.com?subject=something" in MAILTO address
MAILTO=`echo $@ | awk -F\: '1ドル ~ /mailto/ {print 2ドル}'`

# force %d-%m%-Y dateformat
export LC_TIME=fr_FR;

# Check if Thunderbird is running. (Ugly hack, remote options doesn't work)
TBNUM=`ps -A | grep -c thunderbird-bin`;

if [ $TBNUM -eq 0 ]; then
# No running Thunderbird instance: fire up a new copy of the email client.
if [ -z $MAILTO ]; then
# No email address, just run Thunderbird
exec $THUNDERBIRD &
else
# Run Thunderbird and open a compose window with the address 1ドル in the To: field
exec $THUNDERBIRD -mail "mailto:$MAILTO" &
fi
else
if [ -z $MAILTO ]; then
# No email address: open inbox.
PARAM="xfeDoCommand(openInbox)";
else
# Start new compose window with the address 1ドル in the To: field
PARAM="mailto($MAILTO)";
fi

# Open new compose window, or inbox in an already running Thunderbird instance.
exec $THUNDERBIRD -remote "$PARAM" &
fi
