问题
Example: I have a file: FILENAME.EXT and would like to extract FILENAME without the .EXT I want to be able to use the extensionless filename for a command which only accepts filenames without its extensions. I have a utility called BCHECK which accepts as its argument a filename with no extensions. Using BCHECK *. does not work because all the files have .DAT or .IDX extensions. These files are constantly being renamed, thus I need to provide BCHECK with the new filenames without having to manually enter them.
回答1:
The Unix command for this is basename.
回答2:
For DOS batch files you can look at parameters here. For example, the following command displays the filename without extension for the 0 parameter, which is the name of the batch file.
echo %~n0
UPDATE:
Here's an example that can be added to a batch file.
FOR %%f IN (*.dat) DO bcheck -y %%~nf
This command will run bcheck -y BASENAME for each file with a .dat extension in the current directory. The command is a for loop that contains a parameter %%f. The %%f parameter contains the file's full name. For each file matching *.dat, it will run the command after the DO keyword. The %%~nf indicates to to use the basename (~n) from the parameter (%%f).
