End batch file loop

And every batch file needs to quit, and will do so, when it reaches the last line of code. Each operating system may react in its own way to any of these events. And often there is a difference between ending batch file execution and closing the batch file's console window. Therefore, the statements within the loop will always be executed at least once.

This is similar to the set used in the FOR command, but it can only include file and directory names, not arbitrary text strings.

If varname already exists in the environment, it will be overwritten unlike the control variable in FOR. TXT file in the current directory; each time through the loop the variable x will be set to the name of the next file that matches the file specification.

The order of matches is dependent on the file system, and is totally unrelated to any characteristics of the filenames matched. Whether the new file appears depends on its physical location in the directory structure, a condition over which TCC has no control. To use date, time, size, description, or file exclusion ranges for the set place them just before the filename s , for example:.

To execute the loop once for each line of text in the clipboard, use CLIP: as the file name e. CLIP: will not return any data unless the clipboard contains text. ITERATE ignores the remaining commands inside the loop and returns to the beginning of loop for another iteration, unless DO determines that the loop is finished.

Both keywords may be repeated as often as desired. Numeric input may be entered in either decimal format a sequence of digits or in hexadecimal format "0x" followed by a sequence of 0-F hex digits.

DO loops can be nested, i. You may use any combination of the sorting options below. If multiple options are used, the listing will be sorted with the first sort option as the primary key, the next as the secondary key, and so on:. This avoids the potential problem of processing files more than once.

Purpose: Create loops in batch files. See Description Ranges for details. Each parameter will be assigned in sequence, from left to right, to the loop control variable on consecutive passes through the loop. Sort the files before processing. In the first example, we substitute text: the text string "old" is replaced by the text string "new" if, but only if, the text "old" is present in the file's name. In the second example, we add text: the text "Prefix " is added to the start of the file name.

This is not a substitution. Replacing the "echo Example of a loop" line with your batch file allows any of your batch files to loop or rerun. Note Replacing the "echo Example of a loop" line with your batch file allows any of your batch files to loop or rerun.
