Hello dineshkumarsrk,

A few general comments first:-
  • Your for loop has an extra * which might be confusing when you read this later on.
  • It would be better to use longer variable names to make it clear and to reduce the risk of other things that might call this getting confused.
  • The use of backticks ` is deprecated and the way you do it is wasteful too. You add extra processes where the shell can do integer calculations for you.
  • It would be nice to indent your code for clarity
I have made a few tweaks based on these and your code looks like this:-
Code:
count=1
for source_file in */dnaG.fasta
do
   cp "${source_file}" "${count}"_"${source_file}" fastcancatg
   ((count=$count+1))
done

The cp command you have is saying "Copy the source file and the source file again, but with a prefix of the counter and an underscore writing both files to the target directory fastcancatg" which doesn't make sense. The source file with the prefix does not exist. Can I presume that you want to copy the source file to the target directory with a prefix? Perhaps try this instead:-
Code:
count=1
for source_file in */dnaG.fasta
do
   cp "${source_file}" "fastcancatg/${count}"_"${source_file}"
   ((count=$count+1))
done

Is that nearer to what you are after?


Kind regards,
Robin

virt-copy-in

virt-copy-in(1) 					      Virtualization Support						   virt-copy-in(1)

NAME

       virt-copy-in - Copy files and directories into a virtual machine disk image.

SYNOPSIS

	virt-copy-in -a disk.img file|dir [file|dir ...] /destination

	virt-copy-in -d domain file|dir [file|dir ...] /destination

WARNING

       Using "virt-copy-in" on live virtual machines can be dangerous, potentially causing disk corruption.  The virtual machine must be shut down
       before you use this command.

DESCRIPTION

       "virt-copy-in" copies files and directories from the local disk into a virtual machine disk image or named libvirt domain.

       You can give one of more filenames and directories on the command line.	Directories are copied in recursively.	The final parameter must
       be the destination directory in the disk image which must be an absolute path starting with a "/" character.

EXAMPLES

       Update "/etc/resolv.conf" in a guest:

	virt-copy-in -d MyGuest resolv.conf /etc

       Upload a home directory to a guest:

	virt-copy-in -d MyGuest skel /home

JUST A SHELL SCRIPT WRAPPER AROUND GUESTFISH

       This command is just a simple shell script wrapper around the guestfish(1) "copy-in" command.  For anything more complex than a trivial
       copy, you are probably better off using guestfish directly.

OPTIONS

       Since the shell script just passes options straight to guestfish, read guestfish(1) to see the full list of options.

SEE ALSO

       guestfish(1), virt-cat(1), virt-copy-out(1), virt-edit(1), virt-tar-in(1), virt-tar-out(1), http://libguestfs.org/.
