How to keep first 50 characters of a filename in prompt Windows
To keep only the first 50 characters of a filename in the Windows command prompt, you can use the %variable:~start,length%
syntax to extract a substring from the filename variable.
Here's an example of how you can do this in a batch script:
batch@echo off
setlocal enabledelayedexpansion
set "filename=my_long_filename_that_needs_to_be_shortened.txt"
set "shortened=!filename:~0,50!"
echo Shortened filename: %shortened%
In the example above, we set the filename
variable to the original long filename. Then, we use the %filename:~0,50%
syntax to extract the substring from the filename
variable starting at index 0 and with a length of 50 characters. The resulting shortened filename is stored in the shortened
variable.
Finally, we echo the shortened filename to the command prompt using the %shortened%
variable.
You can replace my_long_filename_that_needs_to_be_shortened.txt
with your actual filename or use the %1
parameter to pass the filename as an argument to the batch script.
