Shell Programming and Scripting

Im hoping someone here can help me with the following please?!

I need to change the position of 3 characters in a set of file names.

I have the follow file name structure c2pMOW051102_winds.nc. I need to change the position of the characters c2p to MOW051102c2p_winds.nc.

Can this be done using the 'sed' command? Or does any one know any other way of doing this?

Thanks for any help!

Sed:

Code:

sed 's/\(.\{3\}\)\(.\{9\}\)\(.*\)/\2\1\3/'

With shell:

Code:

for f in *.nc; do
  t="${f#???}" p="${f%$t}_" h="${t%_*}$p" r="${f#*_}"
  mv "$f" "$h$r"
done
