Command to rename multiple files in one go

Hi all,

I have few directories containing around 96 files each. All I want to rename those 96 files names...Example of filenames is shown below:::

TaeCsp2AS_1635B03.fsa
TaeCsp2AS_1635B04.fsa
TaeCsp2AS_1635B05.fsa
TaeCsp2AS_1635B06.fsa
TaeCsp2AS_1635A11.fsa
TaeCsp2AS_1635A12.fsa
TaeCsp2AS_1635C06.fsa
TaeCsp2AS_1635C04.fsa

here I want their names to be like

TaeCsp2AS_1635_B03.fsa
TaeCsp2AS_1635_B04.fsa
TaeCsp2AS_1635_B05.fsa
TaeCsp2AS_1635_B06.fsa
TaeCsp2AS_1635_A11.fsa
TaeCsp2AS_1635_A12.fsa
TaeCsp2AS_1635_C06.fsa
TaeCsp2AS_1635_C04.fsa
it only need to replace TaeCsp2AS_1635 with TaeCsp2AS_1635_ i.e, we have to append a _ with 1635..

Have a look at the rename command or a simple for loop.

m newbiw here , tried a lot ,, got many commands to rename single file, but didn't get any usefull one for renaming bunch of files simultaneously

man rename

Basically - "rename <expression> <replacement> <file>...", and the ... is for multiple files

Code:

...

DESCRIPTION

      rename  will  rename  the specified files by replacing the first occur‐

      rence of expression in their name by replacement.

...

so your sample would imply that "rename TaeCsp2AS_1635 TaeCsp2AS_1635_ TaeCsp2AS_1635*"
should do the job.
