+# Colored MOTDs Setup 
+
+![](0.png)
+
+In this tutorial we're going to take a look at how to setup a colorful MOTD anytime you wish to ssh into your machines 
+
+## **Initial Setup**
+
+First install the required dependencies:
+    
+    
+    [ 10.10.14.13/23 ] [ /dev/pts/22 ] [~]
+    → sudo apt install imagemagick openjdk-17-jdk coreutils perl git
+    	
+    
+
+Then clone the Util-Say repository:
+    
+    
+    git clone https://github.com/maandree/util-say
+    	
+    [ 10.10.14.13/23 ] [ /dev/pts/26 ] [~/Tools]
+    → git clone https://github.com/maandree/util-say
+    Cloning into 'util-say'...
+    remote: Enumerating objects: 2216, done.
+    remote: Total 2216 (delta 0), reused 0 (delta 0), pack-reused 2216
+    Receiving objects: 100% (2216/2216), 700.67 KiB | 1.67 MiB/s, done.
+    Resolving deltas: 100% (854/854), done.
+    
+    [ 10.10.14.13/23 ] [ /dev/pts/26 ] [~/Tools]
+    → cd util-say
+    
+    [ 10.10.14.13/23 ] [ /dev/pts/26 ] [~/Tools/util-say]
+    → make
+    
+    #you need to type make in order to generate the util-say.jar file that the scripts are using.
+     
+    [ 10.10.14.13/23 ] [ /dev/pts/26 ] [~/Tools/util-say]
+    → ls -lash img2ponysay
+    4.0K -rwxr-xr-x 1 nothing nothing 582 May 28 16:20 img2ponysay
+    	
+    
+
+here the file we're looking for is called img2ponysay
+    
+    
+    [ 10.10.14.13/23 ] [ /dev/pts/26 ] [~/Tools/util-say]
+    → cat img2ponysay
+    #!/usr/bin/env bash
+    
+    magnified='1'
+    file='-'
+    dash=0
+    chroma=1
+    c=0
+    platform=xterm
+    
+    for arg in "$@"; do
+        if [ $c = 1 ]; then
+            c=0
+            chroma="$arg"
+        elif [ $dash = 1 ]; then
+            file="$arg"
+        elif [ "$arg" = "--" ]; then
+            dash=1
+        elif [ "$arg" = "-2" ]; then
+            magnified=2
+        elif [ "$arg" = "-c" ]; then
+            c=1
+        elif [ "$arg" = "-p" ]; then
+            platform=linux
+        else
+            file="$arg"
+        fi
+    done
+    
+    java -jar "$(dirname "$0")/util-say.jar" \
+    --import image --magnified $magnified --file "$file" --balloon n --export ponysay --balloon y --file - --chroma "$chroma" --platform $platform	
+    
+    
+
+Next we're going to use a relatively small image to convert to our motd:

+    
+    
+    [ 10.10.14.13/23 ] [ /dev/pts/26 ] [~/Tools/util-say]
+    → ./img2ponysay -- ~/Pictures/smallzero.png > motd.txt
+    Picked up _JAVA_OPTIONS: -Dawt.useSystemAAFontSettings=on -Dswing.aatext=true
+    
+    [ 10.10.14.13/23 ] [ /dev/pts/26 ] [~/Tools/util-say]
+    → cat motd.txt
+    
+    
+
+As you can see, a tiny image can make a very large motd, and you need to be careful of the size of the image you choose to put as your MOTD:

+    
+    
+    [ 10.10.14.13/23 ] [ /dev/pts/26 ] [~/Tools/util-say]
+    → cp motd.txt /etc/motd	
+    
+
