Moving files to different directories

Question

I'm trying to move media and other files which are in a specified directory to another directory, which will be created if it does not exist. And, I'm trying to create a directory where the remaining files with different extensions will go. My first problem is that my script is not making a new directory and it is not moving the files to other directories. How can I move files with different extensions to one directory?

This is what i have had so far. Please correct me where I'm wrong and help modify my script:

#!/bin/bash
From=/home/katy/doc
To=/home/katy/mo #directory where the media files will go
WA=/home/katy/do # directory where the other files will go
 if [ ! -d "$To" ]; then
   mkdir -p "$To"
 fi
cd $From
find . -type f -name"*.mp4" -exec mv {} $To \;

Answer 1

Try this:

#!/bin/bash
# Call this script with the extensions you want to move.
# E.g.,     ./script mp4 avi flv
From="/home/katy/doc"
To="/home/katy/mo" #directory where the media files will go
WA="/home/katy/do" # directory where the other files will go
 if [[ ! -d "$To" ]]; then
   mkdir -p "$To"
 fi
cd "$From"
for i in "$@"; do # You could also hard code this: for i in mp3 mp4 avi; do
  find . -type f -name "*.${i}" -exec mv "{}" "$To" \;
done

{ and } are special characters. I think that adding a bunch of quotes to your script will help make it clearer and work better.
