Hi,

I have some .dat files in some directories , i want them to be moved to another directory by changing file names.

for ex:

cat > /ai/rcmid/feb_files/temp/temp.txt
aaa.dat
bbb.dat

rm -rf main
rm -rf a001
rm -rf a002
mkdir main
mkdir a001
mkdir a002
touch a001/aaa.dat
touch a001/bbb.dat
touch a002/aaa.dat
touch a002/bbb.dat
while read fname1
do

c=1
while [[ $c -le 2 ]]
do
  mv /ai/rcmid/feb_files/temp/a00"$c"  /ai/rcmid/feb_files/temp/main/"${fname1}_${c}"
   	
let c=c+1
done

done </ai/rcmid/feb_files/temp/temp.txt

Here i am unable to change the .dat names, the above code is creating multiple directories which is not expected. can you please help.

You did not cd, so where is this always running?

First outer loop reads aaa.dat and first inner loop has c=1, so if there is a /ai/rcmid/feb_files/temp/a001 then it moves to /ai/rcmid/feb_files/temp/main/aaa.dat_1 which is not your desired first file or dir.
