DateTime Stamps for filenames in Batch files

Computer > Programming > Batch Files


When working with MS-Windows batch file jobs, many times I need to create an output log file that will contain in its file name the specific date, time or both in its filename. In order to do this I need the filename in an environmental variable so I can fill in information using the '>>' redirectors after executing my batch commands.


I developed 3 batch files that do exactly that and here I share them with you.

Date_time_stamps.zip


date2file.cmd
Sets a date stamp to an environmental variable of your choice.

Usage:

c:>\date2file.cmd variable


Result: %variable% = YYYYMMDD


Example:
If today is 4/7/2010 then running


c:>\date2file.cmd mystamp


an environmental variable with name mystamp is created with value 20100704


time2file.cmd
Sets a time stamp to an environmental variable of your choice.

Usage:

c:>\time2file.cmd variable



Result: %variable% = hhmm


Example:
If it is run on 17:34 then  

c:>\time2file.cmd mystamp


an environmental variable with name mystamp is created with value 1734

dt2file.cmd
Sets a datetime stamp to an environmental variable of your choice.

Usage:

c:>\date2file.cmd variable



Result: %variable% = YYYYMMDDhhmm


Example:
If it is run on 4/7/2010 5:23 then running


c:>\dt2file.cmd mystamp


an environmental variable with name mystamp is created with value 201007040523
