I thought I would share my DOS progress bar I have been quietly working on over the years. It processes text files containing PC names. The idea would be to process commands etc on computers etc as needed.
The script is written in a DEMO fashion where it creates its OWN PC lists etc, and processes those. You would need to strip out the parts you need to process your own PC name list etc.
This progress bar function is part of my larger collection of scripts I use to do remote remediation on computers.
NOTE: This script/code relies strongly on NTFS formatted volumes. FAT32 support is not possible. The script relies a lot on NTFS-streams.
Please give credit where credit is due when using the code, that is all.
Code: Select all
