The rdals utility gives users access to enhanced metadata that provides titles for RDA directories in /glade/p/rda/data as well as descriptions for files in the /glade/p/rda/data/dsnnn.n subdirectories. Some data sets may contain incomplete metadata or file list information due to ongoing development.
Enter rdals -h at your command line for a description of how to use the utility.
The utility displays four columns of information. When listing directories, the columns are:
Directory Name, Data Volume, File Count, Brief Description
When listing files, they are:
File Name, Data Size, Data Format, Brief Description
A leading letter is displayed on each line to indicate what type of item is listed:
Here is a sample of the output from rdals /glade/p/rda/data/:

Usage: rdals [-d] [-f] [-N] [-h] [-r] [-D DelimitSymbols] [-R RecursiveLevel] [Directory/File List]
Nothing is displayed if neither directory nor file information matches information stored in the RDA database.
To check directories and files in data set dsnnn.n:
Change to the data set directory.
cd /glade/p/rda/data
Execute rdals, adding the recursive option -r to check directories and files further in the subdirectories (or cd to a subdirectory to check the files).
rdals -r dsnnn.n
Or:
Pass an absolute path to rdals.
rdals /glade/p/rda/data/dsnnn.n/
If your current directory is in another data set directory, such as /glade/p/rda/data/ds277.7, you can pass a relative path to the target directory.
rdals ../dsnnn.n/ or rdals ../dsnnn.n/*
