[Tool] SYSCOPY (Autoexec+Config backup)

[os2fan2]

Back in 1992, i wrote this little batch file, to save AUTOEXEC.BAT to somename.BA_ abd CONFIG.SYS to somename.SY_, That is matched files have matched 'somename'. It is actually handy enough that it's been modified a number of times.

Now, you can save AUTOEXEC.ext and CONFIG.ext (eg .DOS, .W40, .WOS, .WIN), or copy from or to a directory (eg c:\disks\floppy\AUTOEXEC.BAT etc. One use, is when you make a DOS vm, you just install DOS as the manufacturer wants, and then run this batch file to copy A:\VPC-C.

Touching files to the current date/time gets around QEMM updating files you just replaced.

syscopy c:\ d:\saved\msdos saves A and C to d:\saved\msdos.ba_ and .sy_

syscopy d:\mboot .wos /! restores mboot.sy_ to config.wos and mboot.ba_ to autoexec.wos and updates dates

Code: Select all

@echo off
::~  restore autoexec config

Hm. I had a CONFIG.SYS with around 8 different configurations and an AUTOEXEC.BAT which was around 100 lines and called multiple sub-batchfiles depending on which config was selected. It was a pain to keep this working, as every program that tried to add/remove something from these files eventually screwed up and I had to replace them with known-good files again. I made batch files just for this purpose (to save and restore the config.sys/autoexec.bat files) because it happened so often
