Display information on Stata data sets and variables in current directory

    ^dtainfo^ [ varname |
        ^,^ ^s^ort^(fname^|^obs^|^var^|^double^|^float^|^long^|^integer^|^byte^|^miss)^ ]


Description
-----------

^dtainfo^ displays summary information about Stata-format data sets and variables
in the user's current directory.  ^dtainfo^ can be used to display information
about all Stata-format (^*.dta^) data sets in the current directory or to search
for and display information about all occurrences of a particular variable in
those data sets.

When no variable name is specified, ^dtainfo^ surveys each data set and reports
the date and time it was last saved, the total number of observations and
variables, the number of each type of variable, and the number of missing
observations.  When a variable name is specified, ^dtainfo^ searches each data
set for that variable, reporting the data sets that contains it and the
variable's type, number of observations, and number of missing observations.


Options
-------

^s^ort^(fname^|^obs^|^var^|^double^|^float^|^long^|^integer^|^byte^|^miss)^
    specifies the sort order for the information in the report:

    argument    report is sorted by
    --------    -------------------
    ^fname^       filename
    ^obs^	  number of observations
    ^var^         number of variables
    ^double^      number of type double variables
    ^float^       number of type float variables
    ^long^        number of type long variables
    ^integer^     number of type integer variables
    ^byte^        number of type byte variables
    ^miss^        number of missing observations
