Setting a DOS variable

[nkhimani]

Folks,

I need help ... in UNIX world it is relatively easy to set a variable
from a process. For example:
$ junk=`ls -altr | tail -1 | awk '{print $9}'`
$ echo ${junk}

This sets variable 'junk' to the file name of most recent file.

What's the trick to perform this in DOS world? TIA,

-NK

XP has no DOS. It has, instead, the CMD shell which resembles DOS.
XP calls similar things environment variables. One sets an environment
variable via the set command in the cmd shell. It would be best to look in
Help & Support before proceeding further.

within a batch file:

for /f %%i in ('dir /b/o:d/a:-d c:\dirname\filemask') do set junk=%%i

/a:-d suppresses directory names
/o:d sorts in order of date. For the earliest, use /o:-d
