UNIX for Dummies Questions & Answers

Hi Guys,

I am a newbie to Unix . I am going through Unix Commands. I have a issue . Please try to find a solution for this...

Example: I am in my current directory now which contains a folder name 'Test' . The folder Test contains some files with .txt extension.Inside the Test folder I am having some more sub-folders.The sub-folders also contain some .txt files. My aim is to rename all the .txt files in Test folder and its subdirectories to .my extension from my current directory.

Example:

[mraghunandanan@localhost ~]$ ls
999 lkj Public sedscript1 Test
Desktop lop qwe Session_01222009 til00
Documents Mail return_sqlvalue.ksh si00 til01
Download ml SCRIPTSER si01 Videos
file.sql Music sdf sort vishwan
insert_file.sql.sql my_jil sdft00 syed workspace
jj1 p1.pl sdft01 tail
jj.gz Pictures sedfile Templates


[mraghunandanan@localhost Test]$ ls
cc hh.txt kk.txt ll.txt mm.txt nn.txt test1 test2 test3

So , Test is the folder which contains .txt files and test1 ,test2 and test3 are subfolders which contains .txt files.

Please help me guys...

Regards,

Mahesh..

try this in ksh

====code==========
find ./Test -type f -name '*.txt' > file1


while read line
do
mv $line $line.my
done < file1

echo "Renamed files to *.my"

Try the following ...

Code:

curdir=`pwd`
for filename in `find ./Test -type f`
do
cd $curdir
echo "filename: $filename"
cd `dirname $filename`
oldfilename=$filename
echo "oldfile: $oldfilename"
newfilename=`basename $filename .txt`
echo "newfile: $newfilename"
pwd;
mv $newfilename.txt $newfilename.myextension
done

use a while loop

Code:

find ./Test -type f | while read FILE
do
 ...
done
