Dos Batches: write to files without a line ending?

Question

I have a situation while writing a dos batchs script. A tool I am using to calculate CRC (checksum) of a text string requires the text to be in a file. The data I am trying to get the CRC for is a filename, but when using a batch to put this filename into a text file to calculate CRC, the batch script naturally puts the line ending (CR/LF) and a blank line at the end. As this causes the CRC to be wrong, it is a problem.Is there any way to get a batch script to write to a text file without appending a line ending? IE to output a single line unfinished to file?-K.Barad

Answer 1

You can subtract the CR+LF value from the checksum...

But the receiving computer will also include the CR-LF in it's calculation of

the check sum as well, so it should still be the same...

You may have to go down to the C/C++ level in order to accomplish this, as

I do not see any native DOS command that truncate or trim strings.

DOS batch commands are not suited for string handling.
