<oerjan> learn shebang_args_or_input is similar to print_args_or_input, but for other scripting languages like perl or python. E.g. if you have a python script that pipes stdin, replace the usual shebang line by #!/hackenv/bin/shebang_args_or_input python .

#!/bin/bash
if [ ! "$1" ]
then
    PASTE=-
else
    PASTE="$1"
fi

PASTENUM="$RANDOM"

mkdir -p $HACKENV/paste

url paste/paste."$PASTENUM"
cat "$PASTE" > $HACKENV/paste/paste."$PASTENUM"
