These freeware make the task of renaming multiple files at once quite effortless and efficient. %%a is the variable which receives the sub-directory name in each iteration.Here is a list of best free batch file renamer software for Windows.%1 is the command line variable referring to parent directory./b displays it in bare format, i.e., only names are returned and date, time and other info are not./ad displays only directories (ignores files).
To list the sub-directories in parent directory, we use the command:- dir /ad /b %1 tokens=* means to consider each line as a single token and pass to the command.usebackq specifies backquouted string is a command to be evaluated.(Note that the dir command is enclosed within backquotes(`) ).The option string is :- "usebackq tokens=*" To enable us to issue a dos command to be evaluated, we need to use the /F option. These are represented by %1 and %2 (first and second parameters). The command here assumes that the required parent directory name and string to be appended are passed on as command line parameters. The format of 'for' command used here is:- for /F %variable IN (`command`) do command Let's see how this for command accomplishes that. For the given requirement, we need to do the following:-ġ) Accept name of folder which contains sub-folders to be renamed(in your example, it is Workspace).Ģ) Accept the string to be appended to the end(in your example, it is your name).ģ) List the names of sub-folders in the folder.Ĥ) Rename by appending the string to original name. This is the DOS 'for' command, which iterates over given set of items, and for each element in the set, performs the given action. You can use the following command within your batch file:- for /F "usebackq tokens=*" %%a in (`dir /ad /b %1`) do ren %1\%%a %%a%2 See the following references from Microsoft for more details: %%f holds the full pathname, which is fine for the first argument to the rename command, but for the second argument, we only want the filename+extension, thus the ~nx modifier prepended to our variable name.īy the way, when using this for loop on the command line (rather than part of a batch file) you only want to use one % instead of %% for your variable name. What that does is this: for each directory in the path (within parenthesis), assign the directory name to the variable %%f, then rename the directory %%f to the name in the format you want (with your name attached). I tested this on Windows 7, but it should work at least as far back as with Windows XP. You could use for to loop through each directory and rename it like so: for /D %%f in (C:\path\to\Workspace\*) do rename "%%f" "%%~nxf_myname"
