Current Page: NeXtMidas Training Working with Files Basic File Commands STATUS - Listing file headers
- - | The `STATUS` Command: The `STATUS` command is used to show details about a file For Midas (Blue) files, `STATUS` shows information in the Blue header.
        nM> status apenny.prm
        DataFile (BLUE)    :  file:/home/burdell/nxm230/nxm/sys/dat/apenny.prm
        Data Rep (H/D)     :  EEEI / EEEI
        Number of Elements :  128.0
        File Type          :  2000
        Data Format        :  SB - Scalar Byte
        Write Protect      :  false
        Abscissa units     :  No applicable units (U)
        Abscissa start     :  0.0
        Abscissa delta     :  1.0
        Frame Length       :  128
        Secondary units    :  No applicable units (U)
        Secondary start    :  0.0
        Secondary delta    :  1.0
  - For other file types, `STATUS` shows generally useful information like: The number of bytes in the file (XML or TXT files) That particular file type's header information (JPEG or SHP) In general, any file type whose file handler subclasses `BaseFile` and can be `STATUS`ed. Isn't Java great?
        nM> status airports.csv{headerrows=1}
        CsvFile   : file:/home/burdell/nxm230/nxm/sys/dat/airports.csv
        Rows      : 726
        Columns   : 4
        Header    : First Row
        Column Name=AIRPORT_NAME    Format=??
        Column Name=CODE            Format=??
        Column Name=LATITUDE        Format=??
        Column Name=LONGITUDE       Format=??
The `/KEY` or `/K` switch can be used to show the Midas keywords. The `/DATA=` or `/D=<num_elements>` switch can be used to show the data in the file (by running DATALIST).
