我对pdf bash脚本的减价有什么问题？

Question

I am trying to make a script that makes a pdf in a specific directory using pandoc and markdown. The command I am trying to run works when I run it in a shell, but not when I run it through the script. I have tried using the --verbose flag to get some debug output, but pandoc complains about not recognizing the option.

Here is my script so far.

#!/usr/bin/env bash

IN_FILE=$1
OUT_DIR=$2
CURRENT_DATE="$(date +%d%m%Y)"
SUBSTRING=${IN_FILE%.*}

if [[ ${IN_FILE: -3} == ".md" ]]; then
    OUT_FILE=${SUBSTRING}-${CURRENT_DATE}.pdf
    pandoc -r markdown -o ${NOTES_DIR}/${OUT_DIR}/${OUT_FILE}
else
    echo "Wrong file type. Needs to be .md"
fi

Turns out I had forgotten to specify the in file in the call to pandoc. I just did not see it.

Here is the updated script, works fine now.

#!/usr/bin/env bash

IN_FILE=$1
OUT_DIR=$2
CURRENT_DATE="$(date +%d%m%Y)"
SUBSTRING=${IN_FILE%.*}

if [[ ${IN_FILE: -3} == ".md" ]]; then
    OUT_FILE=${SUBSTRING}-${CURRENT_DATE}.pdf
    pandoc -r markdown -o ${NOTES_DIR}/${OUT_DIR}/${OUT_FILE} ${IN_FILE}
else
    echo "Wrong file type. Needs to be .md"
fi
