Shell Programming and Scripting

Hi Everyone !

i want to make an application which is written in shell script and in Bourne shell (sh)

i want, when my script is executed, it read all the files in the directly and move them to folders according to their extension.

suppose i have a files:

test.txt
test.jpg
test.docx
test.tgz

all files txt goes to directory txt, jpg extention files goes to folder jpg and same the docx files to docx directory, while the achive files go to archive directory

and in the archive directory, it creates directory as test (basename) and unpack the files in test directory.

any idea will be appreciated, since i'm not a script programmer

Thanks in Advance

Here is a start.. You can figure out the rest

Code:

 
#!/bin/ksh
IN_DIR=/tmp/junk
 
for f in `ls -1 $IN_DIR`
do
  ext=$(echo $f | cut -d"." -f2)
  if [ "$ext" = "doc" ]
  then
    OUT_DIR=/tmp/junk1
  elif [ "$ext" = "jpg" ]
  then
    OUT_DIR=/tmp/junk2
  else
    OUT_DIR=/tmp/junk3
  fi
 
mv $IN_DIR/$f $OUT_DIR
  if [ $? -ne 0 ]
  then
    echo "Error: Failed mv $IN_DIR/$f $OUT_DIR"
  fi
 
done
