'A great deal of what makes life congenial is a sequence of little white lies' - Philip TerzianįOR - Loop through a set of files in one folder.įOR /R - Loop through files (recurse subfolders). Non-numeric lists can use a standard FOR command:įOR %%G IN (Sun Mon Tue Wed Thur Fri Sat) DO echo %%GįOR /l %%G in (1,1,1000) DO copy SourceFile.txt NewFile%%G.txt įOR does not, by itself, set or clear the Errorlevel. If you are using the FOR command at the command line rather than in a batch program, use just one percent sign: %G instead of %%G. This will cause slow performance if the loop is (pointlessly) counting up to a large number. If EXIT /b used with FOR /L, the execution of the commands in the loop is stopped, but the loop itself continues until the end count is reached. If the start,step,end are left null or (0) then the command will loop indefinitely, Ctrl-C will cancel the whole script. If the start,step,end are chosen such that end will never be reached, the loop will not run at all. In addition to integer numbers, hex and octal numbers can also be compared within certain limits.

The numbers must all be within the range of 32 bit signed integer numbers (-2,147,483,648 through 2,147,483,647) (0,5,19) will generate the sequence 0 5 10 15 (1,1,5) will generate the sequence 1 2 3 4 5

Read the main FOR introduction page for a full description of assigning the replaceable %%parameter.įOR parameters are used in all variations of the FOR command. In a batch file use %%G (on the command line %G) FOR parameters (%%A – %%Z) In ( brackets), several commands, one per line.

This can be a single command, or if you enclose it Step : The amount by which to increment the sequenceĬommand : The command to carry out, including any parameters. SyntaxįOR /L %% parameter IN ( start,step,end) DO command Conditionally perform a command for a range of numbers.
