Hi Andrew, That is a very elegant one liner. So this one just changed the H to a J
Let's see if some light is entering the brain at this late hour So this - for x in 6H9* - is saying for the input 6H9* (all files in the directory with 6H9as a prefix) then do the exchange of the J for the H using the move command mv which is another way to rename; -v for verbose will print the outcome on screen and after that it looks like the swap but I am lost from this point. But grateful.
Fix missing " chars.... So, in plain bash for your data files, it could be as simple as follows: for x in *H*;do mv -vi "${x}" "${x/H/J}";done and to reverse the changes: for x in *J*;do mv -vi "${x}" "${x/J/H}";done A.
