In the preceding example, each file that has the .doc or .txt extension in the current directory is substituted for the %f variable until the contents of every file are displayed. To use this command in a batch file, replace every occurrence of %f with %%f. Otherwise, the variable is ignored and an error message is displayed.
This command parses each line in myfile.txt. It ignores lines that begin with a semicolon and passes the second and third token from each line to the for body (tokens are delimited by commas or spaces). The body of the for statement references %i to get the second token, %j to get the third token, and %k to get all of the remaining tokens. If the file names that you supply contain spaces, use quotation marks around the text (for example, File Name). To use quotation marks, you must use usebackq. Otherwise, the quotation marks are interpreted as defining a literal string to parse.
Let's take a look at an example annotation of the above image f9a9a175f26d4b26bca3a5338cc1405e.jpg in YOLO Darknet format. The corresponding f9a9a175f26d4b26bca3a5338cc1405e.txt file contains the annotations for objects in the image.
In the .txt version of this document, values are quoted to indicate that they are to be taken literally. When using these values in protocol messages, the quotes MUST NOT be used as part of the value. In the HTML version of this document, values to be taken literally are indicated by the use of this fixed-width font. 781b155fdc
