pdf-delete-annotations - Delete Annotations from PDFs

Taken from this gist.

# Check if the input argumetn is a PDF file
if [[ -f "$1" && "$1" == *.pdf ]]; then
    pdftk $1 output /tmp/uncompressed.pdf uncompress
    LANG=C sed -n '/^\/Annots/!p' /tmp/uncompressed.pdf > /tmp/stripped.pdf
    pdftk /tmp/stripped.pdf output $1 compress
fi

pdf-delete-first-page - Delete first page of PDF

The requirement is to have pdftk or stapler installed.

# Check if the input argumetn is a PDF file
if [[ -f $1 && $1 == *.pdf ]]; then
    if type stapler > /dev/null 2>&1; then
        stapler del "$1" 1 /tmp/pdftk_out.pdf && mv /tmp/pdftk_out.pdf "$1"
    elif type pdftk > /dev/null 2>&1; then
        pdftk "$1" cat 2-end output /tmp/pdftk_out.pdf && mv /tmp/pdftk_out.pdf "$1"
    else
        echo "Neither pdftk nor stapler are installed"
    fi
