    I was asked to write a program to resize thousands of images which were gonna be uploaded to a website. Images had to be the same height for them to look organized in gallery.

    This is a learning opportunity

    +

    Since I don't have much of an experience on shell scripting, I was Ducking everything. I learned to do few things during this task.

    +
      +
    1. For loops in shell script
      2. +
    2. Getting list of files
      3. +
    3. Correct syntax for resizing with ImageMagick
      4. +
    +

    After reading tutorials and looking at examples everything felt as simple as lego. I just needed to put them together.

    +

    Here is image_shrinker.v0.1_alpha.sh :

    +
    #!/bin/sh
+mkdir ../output
+for image in ./*
+do
+    convert $image -scale 1000000x800 ../output/$image
+done
+
    + + +

    This version has problems which I can't call "feature" 😁️ :

    +
      +
    1. Resolution is hard coded. Btw, only way to define resolution is in WIDTHxHEIGHT format AFAIK.
      2. +
    2. Script must be in same directory as images
      3. +
    3. PWD must point to the directory where script is
      4. +
    +

    Adjustable resolution

    +
    #!/bin/sh
+mkdir ../output
+WIDTH=$1 ; HEIGHT=$2
+
+for image in ./*
+do
+    convert $image -scale $WIDTHx$HEIGHT ../output/$image
+done
+
    + + +

    This fixes the hard coded resolution problem but new problem is that the user has to know that WIDTH and HEIGHT must be given. I fix that by showing correct syntax to the user and then exiting :

    +
    #!/bin/sh
+
+if [ $# -lt 2 ]
+then
+    echo "USAGE:"
+    echo -e "\t\$IMAGE_DIRECTORY/image_shrinker.sh WIDTH HEIGHT"
+    exit 1
+fi
+
+WIDTH=$1 ; HEIGHT=$2
+mkdir ../output
+
+for image in *
+do
+    convert $image -scale $Resolution ../output/$image
+done
+
    + + +

    Here is some other attempt to make code a bit more flexible in terms of where images can be and where output can go. Actually no but that is what I was going for 😜️

    +
    #!/bin/sh
+
+DIR=`pwd`
+
+for image in ./*.*
+do
+#   Below code will scale images to 800px height without breaking aspect ratio
+    convert $DIR/$image -scale 10000x800 -write $DIR/../output/$image
+done
+
    + + +

    It is hard to ask for help (especially after torturing with my code) but if you would like to give me feedback and advice, reply to toot of this post.
