I am trying to loop over all the netcdf files in a certain directory with bash, manipulate them with NCO, and then write the result to new files, all with different names. I am thinking of something like this:

for f in *.nc 
do ncap2 -s "vt = vt*1.3" $f2$ 
done

The second line manipulates the variable 'vt'. The results should be stored in netcdf files with similar names as the ones that I'm looping over. So f.e., I want the manipulated file to be called test_m.nc if the original file is called test.nc. The question is: what should I write instead of $f2$ to achieve this result? Thanks!

This loops over the files and replaces the string foo in the input filename with the word bar in the output filename:

for f in *.nc 
do ncap2 -s "vt = vt*1.3" $f ${f/foo/bar} 
done

Another possibility is to create a counter outside the loop, increment it inside the loop, and include it in the output filename.
