Here's a simple script that will allow you to open multiple files in Preview as a collection from the Terminal. This will allow you to browse multiple files in a single Preview window, very handy if you don't like Finder but dig the Terminal :)
Example of usage:
[guybrush@powerbook guybrush]$ cd photos
[guybrush@powerbook photos]$ preview *.jpg *.png
#!/bin/sh
# A simple bash script that uses Applescript to
# open multiple files in Preview. For example:
# "preview hello.png world.gif *.jpg"
if [ -z "$*" ]; then
echo "Usage: $0 [FILE(S)]"
exit
fi
PWD=${PWD//\//:}
for file in $*;
do
if [ -n "$FILES" ]
then
FILES="$FILES, \"$PWD:$file\""
else
FILES="\"$PWD:$file\""
fi
done;
osascript<<EOF
tell application "Preview"
activate
open {$FILES}
end tell
EOF
