NWS12 to NWS13

tool to convert OWI’s NWS12 formatted ascii files (fort.22{1,2}) to OWI’s NWS13 NetCDF4

`diff` Also Compares Directories

Short post so that I can remember this everytime I need to do something similar!

Using diff on more than individual files #

The quick and dirty explaination is that the GNU/Linux diff command has an -r flag to recursively compare two folders. The command help indicates that it is shorthand for the full --recursive flag, which might be easier to remember.

diff --help

# ...
  -r, --recursive                 recursively compare any subdirectories found
# ...

Example #

In the following example, “Only in” shows that particular files are only found in one of the folders. By default, matching files are not shown. If a file can be found in both folders and the two versions differ, the normal diff output is provided along with the modified times. All together these details provide a good summary of what a user might want to know when comparing two directories.
