statafilesystem's Introduction

FILESYS

A Stata program to access and modify file system properties. Currently, the program/plugin allow users to:

  1. Access file attributes
  2. Set the file to be executable globally or for the owner only
  3. Set the file to be readable globally or for the owner only
  4. Set the file to be writable globally or for the owner only
  5. Make a file readonly protected

Requirements

Plugin is compiled under Java 8. Should not be a problem for most installations of Stata, but if you have an older JVM you can alter the JVM used by setting the appropriate properties. To see the java property names use query java.

Examples

Get file attributes for the auto.dta data set and print them to the Stata console

. filesys `c(sysdir_base)'a/auto.dta, attr dis

----------------------------------------------------------------------------------------------------

    Canonical File Path      /Applications/Stata/ado/base/a/auto.dta
    Parent Path              /Applications/Stata/ado/base/a
    File Name                auto.dta
    Is Symbolic Link         false
    Is Regular File          true
    Is Executable            false
    Is Hidden                false
    Is Readable              true
    Is Writable              true

You can display the returned results afterwards as well

. ret li

macros:
         r(iswritable) : "true"
         r(isreadable) : "true"
         r(parentpath) : "/Applications/Stata/ado/base/a"
           r(ishidden) : "false"
           r(filename) : "auto.dta"
       r(isexecutable) : "false"
      r(canonicalpath) : "/Applications/Stata/ado/base/a/auto.dta"
        r(absoluepath) : "/Applications/Stata/ado/base/a/auto.dta"
           r(filesize) : "6443"
        r(regularfile) : "true"
            r(symlink) : "false"
        r(accessednum) : "1765432343000"

            r(created) : "20nov2015 05:44:54"

Make the auto.dta file executable and print the attributes to the console

. filesys `c(sysdir_base)'a/auto.dta, x(on) glo dis

Remove the executable property from the auto.dta file.

statafilesystem's Issues

Access to file owner property

Private email from colleague Megan Clifford asked about accessing users from Stata. Checked plugin to see if it was possible to access file owner property from plugin but was not available.
