how to combine showinfo?
Added by Noam Chomsky about 5 years ago
I like to use showinfo but I don't understand how to show only certain info. For example if I want to see names and levels. I am not sure if it's useful to see only levels when I don't see the names of such variables. I tried cdo showname showlevel file.nc but doesn't work.
Hey Karin,
Thank you for the suggestion. I think part of my question was not very well written. The sinfon is what I was looking, but is there a way to only print the first part 3 parts but NOT print the Time coordinate part? That takes a lot of space in the screen and I need to scroll up to find the info I really need.
Also in regards to the showlevel and the other show*something* operators, how are those useful if the name of the variable is not printed? For example in my data if I use showlevel I get this
1 2 3 4 5 6 7 8 9 10 11 12 13
1 2 3 4 5 6 7 8 9 10
1 2 3 4 5 6 7 8 9 10 11 12 13
1 2 3 4 5 6 7 8 9 10 11 12 13
1 2 3 4 5 6 7 8 9 10 11 12 13
1 2 3 4 5 6 7 8 9 10 11 12 13
1 2 3 4 5 6 7 8 9 10 11 12 13
0
1 2 3 4 5 6 7 8 9 10 11 12 13
1 2 3 4 5 6 7 8 9 10 11 12 13
1 2 3 4 5 6 7 8 9 10 11
but it's not really that useful because I don't to which variables these levels belong to.
Thanks again.
In my opinion there isn't such operator but you can use your shell with a loop to do it similarly.
To print the variable names followed by their levels to stdout, e.g. for Korn-Shell:
for name in $(cdo showname infile.nc) ; do ; echo "-- ${name}" ; cdo -s showlevel -selname,${name} infile.nc ; done
For my example file it prints
-- rhumidity
100000 92500 85000 77500 70000 60000 50000 40000 30000 25000 20000 15000 10000 7000 5000 3000 1000
-- var3
100000 92500 85000 77500 70000 60000 50000 40000 30000 25000 20000 15000 10000 7000 5000 3000 1000
-- t
100000 92500 85000 77500 70000 60000 50000 40000 30000 25000 20000 15000 10000 7000 5000 3000 1000

I thought so that it needed some kind of hack 
. Thanks for the suggestion!
