如何解决imageMagick 脚本在 Windows 上正常工作，但在 ubuntu 服务器上无法正常工作
我有一个 shell 脚本 (ImageMagick)，可以在图像周围添加一个框架。它在我的 Windows 机器上运行良好。下面是输出图像。
我已经在 ubuntu 服务器（Digital Ocean Droplet）上部署了脚本。当我在那里运行脚本时，它运行良好并且没有出现任何错误，但输出是全黑图像，周围有框架。
脚本代码如下：
#!/bin/bash
ORIGDIR=`pwd` # original directory (builtin)
PROGNAME=`type $0 | awk '{print $3}'` # search for executable on path
PROGDIR=`dirnae frame_edges.sh` # extract directory of program
PROGNAME=`basename frame_edges.sh` # base name of program
cd $PROGDIR # go to that directory
PROGDIR=`pwd` # remove any symbolic link parts
cd $ORIGDIR # return to original directory (opt)
FRAMEDIR='.'/edge_images
cmd_found() { # is this command available?
case "`type $1 2>&1`" in *'not found'*) return 1 ;; esac; return 0
}
Usage() { # output the script comments as docs
# Output the script comments as a manual
echo >&2 "$PROGNAME:" "$@"
sed >&2 -n '/^###/q; /^#/!q; s/^#//; s/^ //; 3s/^/Usage: /; 2,$ p' \
"$PROGDIR/$PROGNAME"
# List the framing edge images available
if cd $FRAMEDIR; then
echo "Framing images (styles) available :-"
ls *.{gif,png,jpg} 2>/dev/null |
sed 's/\.\(gif\|png\|jpg\)$//; s/_\(top\|btm\|lft\|rht\)$//;' | sort -u |
if cmd_found fmt; then
fmt -w 60 | sed 's/^/ /'
else

sed 's/ $/@/; s/[^@]\{5\} /&@/g' |
tr '@' '\012' | sed 's/^/ /'
fi
echo ""

exit 10;
}

# $lft,$rht Optional left and right edge images (usally not uused)
# $card_cover Color of the surrounding cardboard. Defaults to 'SNow'
# $card_inner Color of the inner core of cardboard,producing a
# a thin colored border close to the image.
# Defaults to the average color of 'top' image.
# $card_border The width of the cardboard border (other than the bevel)
# Defaults to 15 or 1/2 'top' width,whatever's greater.
# $roll_images If set to 'true' images have a pattern that should be
# randomly rolled before tiling. Defaults to false.
