Shell Programming and Scripting

Hi,
These are the text file I have

//input1.txt//
cd dir1/dir2/pg1.txt
cd dir3/dir4/pg2.txt
cd dir88/dir5/pg4.txt
cd dir7/dir6/pg5.txt
cd dir8/dir9/pg7.txt

And each text file has some text.

Now I have to write a shell script which reads input1.txt and changes the directory as shown in each line and reads pg1.txt and then copy it to another file namely out.txt. This has to be done recxursively. The code which i Have written is

#!/bin/ksh
 if [ $# -ne 2 ]  # enter the input data file and output file
 then
 echo "Please enter 2 filenames" 
 fi
 infile=$1
 outfile=$2
 while read line
 do
  #read the path of a file and change the path
  cd $line 
  while read line # now reads the file pg1.txt 
  do
   echo "$line" >> $outfile
  done< $line
 done < "$infile"

Here I am able to put data of pg1.txt in out.txt but other files I am not able to do it...Pls help me.....
