This article describes the several steps needed to use the results ofa query (using the FIND filter) as a replaceable parameter in a one ormore batch files. A use for this would be to search for a specificfile and then perform some action on or with this file. The file couldthen be used in one or more batch files as a replaceable parameter.
First, you need to set up a one-line file with the partial command
with no carriage return (CR) or linefeed (LF) at the end (this can bedone with COPY CON by pressing CTRL+Z after the equal sign [=] andpressing ENTER).
The file would look like this on the screen:
C:\>COPY CON INIT.TXT SET VARNAME=^Z
The following steps can be issued from the MS-DOS command prompt or fromwithin a batch file:
Search for a single directory entry and place the results in a text file.
dir | find "dos" > textfile
Append the two files into one batch file using the COPY command as follows:
copy init.txt+textfile varset.bat
Place the contents of the text file in a variable by running VARSET.BAT.
VARSET.BAT sets an environment variable equal to the directory entry foundearlier. This allows the environment variable to be used as a replaceableparameter in later batch files. VARSET.BAT can be called from the commandprompt or from within another batch file.
NOTE: This process works for directory names only if MS-DOS 5.0 or 6.0 isbeing used. Under MS-DOS 5.0 and 6.0, the /B switch must be used when youare searching for a directory name. The following is an example ofsearching for a directory under MS-DOS 5.0 or 6.0.
dir /b | find "dos5" > textfile
NOTE: There is still a 127-character limit to the length of this variable,which includes the variable name and equal sign (=).
