Dear All,

I am good in excel so till now doing with excel but now data is too hugh,more than 8 crore records. So its difucult to downlaod gb's of data of rename the files.
Need to rename few files as
Source filename to destination filename (Vice-versa)
52776631_1_fingerprints_555_13630002_0046_00098555_N.bmp to 52776631_fp_1.pk
52776631_2_fingerprints_555_13630002_0046_00098555_N.bmp to 52776631_fp_2.pk
52776631_3_fingerprints_555_13630002_0046_00098555_N.bmp to 52776631_fp_3.pk
52776631_4_fingerprints_555_13630002_0046_00098555_N.bmp to 52776631_fp_4.pk
52776631_5_fingerprints_555_13630002_0046_00098555_N.bmp to 52776631_fp_5.pk
52776631_6_fingerprints_555_13630002_0046_00098555_N.bmp to 52776631_fp_6.pk
52776631_7_fingerprints_555_13630002_0046_00098555_N.bmp to 52776631_fp_7.pk
52776631_8_fingerprints_555_13630002_0046_00098555_N.bmp to 52776631_fp_8.pk
52776631_9_fingerprints_555_13630002_0046_00098555_N.bmp to 52776631_fp_9.pk
52776631_10_fingerprints_555_13630002_0046_00098555_N.bmp to 52776631_fp_10.pk

_fingerprints_555_13630002_0046_00098555_N.bmp Will be constant for all records.

And then vice-versa.
Environment: Redhat Linux.
Please help me out.Thanks in advance.

awk is a very powerful tool. I advice you to use it.

ls *.bmp | awk -F"_" '{ print $0" "$1"_fp_"$2".pk" }'  | while read a b
do
  mv $a $b
done

Dear Vedat,

i tried for vice versa means from 52776631_fp_1.pk to 52776631_1_fingerprints_555_13630002_0046_00098555_N.pk. Script I modofied is as:
ls *.pk | awk -F"_" '{ print $0" "$1"_"$3"_fingerprints_555_13630002_0046_00098555_N.pk" }' | while read a b
do
mv $a $b
done
=================
incorrect result arises is as:
52776631_9.pk_fingerprints_555_13630002_0046_00098555_N.pk

Please suggest the required changes.Thanks in advance.

change 'ls *.pk' according to your needs. before renaming, see what awk prints.
