SOLVED: Database disk image is Malformed

[sneakie]

This might be a bit of a beginner question, but how do I run the script in this context?

I mean the "#!/bin/bash
cat <( sqlite3 "$1" .dump | grep "^ROLLBACK" -v ) <( echo "COMMIT;" ) | sqlite3 "fix_$1""

I got the sqlite3 commandline utility tool for windows on my main computer, but couldnt figure out how to run the command. Might be a bit slow on the uptake.

Sorry!
