FOR /L
Conditionally perform a command for a range of numbers
syntax FOR /L %%parameter IN (start,step,end) DO command key start : The first number step : The amount by which to increment the sequence end : The last number command : The command to carry out, including any command-line parameters. %%parameter : A replaceable parameter: in a batch file use %%G (on the command line %G)
So (20,-5,10) would generate the sequence (20 15 10)
(1,1,5) would generate the sequence 1 2 3 4 5
Examples
FOR /L %%G IN (1,1,5) DO echo %%G
FOR /L %%G IN (Sun Mon Tue Wed Thur Fri Sat) DO echo %%G
