"Copying with different file name"

Copying with different file name

Hi,

I am new to bash. One needs to copy files with intervals, I use

Code:
#!/bin/bash
for i in `seq 0 2 30`;do
	cp /Volumes/data${i}_b0.dat   /Users/Results2/
done

Now I am wondering to shift the name by whatever number up. I mean I need to copy files:

data0_b0.dat
data2_b0.dat
data4_b0.dat
.
.
.
data30_b0.dat

in another directory with the names

data32_b0.dat
data34_b0.dat
.
.
.
data64_b0.dat


Thanks in advance for your time.

Found it. I just write it here, it might be helpful for others.

Code:
#!/bin/bash
for i in `seq 0 2 30`;do
        let j=$i+2
	cp /Volumes/data${i}_b0.dat   /Users/Results2/data${j}_b0.dat
done

NAME
rbash - restricted bash, see bash(1) RESTRICTED SHELL
If bash is started with the name rbash, or the -r option is supplied at invocation, the shell becomes restricted. A restricted shell is used to set up an environment more controlled than the standard shell. It behaves identically to bash with the exception that the follow- ing are disallowed or not performed: o changing directories with cd o setting or unsetting the values of SHELL, PATH, ENV, or BASH_ENV o specifying command names containing / o specifying a file name containing a / as an argument to the . builtin command o specifying a filename containing a slash as an argument to the -p option to the hash builtin command o importing function definitions from the shell environment at startup o parsing the value of SHELLOPTS from the shell environment at startup o redirecting output using the >, >|, <>, >&, &>, and >> redirection operators o using the exec builtin command to replace the shell with another command o adding or deleting builtin commands with the -f and -d options to the enable builtin command o using the enable builtin command to enable disabled shell builtins o specifying the -p option to the command builtin command o turning off restricted mode with set +r or set +o restricted. These restrictions are enforced after any startup files are read. When a command that is found to be a shell script is executed, rbash turns off any restrictions in the shell spawned to execute the script. SEE ALSO
