Shit, I changed by Github username...

edit-git-config-at-large.sh

# Want to change your Github username? 
# Want to change the url of your self-hosted git remote handler (ie Gogs)?... 

# This solve is to find every .git/config file (which is where each project-related git configuration lives) and edit
# according to your whims. That's where the `sed...` part comes into the play. `sed s/x/y/g` will substitute all
# x for y globally in the given file. The given file in this case is the `find`ers. 
# In the examples, the `-i.bak` part is making a backup just in case which you needn't worry about if shit doesn't hit the fan.

# Note that this given sed parses the git config file globally. Make sure your subsititutions are specific enough. 

# Usage example:
# $ find_git_configs some/where "sed -i.bak s/theold/thenew/g"

# En generale...
find_git_configs() {
	# $1 is wherein to search for git projects, beit your home directory, your host directory, a projects-based directory... wherever you keep your git shit that you want to chagne
	# $2 is what to do upon finding each such git project configuration; should be a shell statement
	# 		(what about the target you ask? i don't know. i'm drunk. the execetuable statement is going to be passsed the file. 
	# 		... for each file do a thing. do things $2. don't ask too many questions and buy me more beers. 
	find $1 -path "*/.git/config" -exec $2 {} \;
}

# Changed username...
find_git_configs ~/ "sed -i.bak s/irstacks/abettername/g"

# Changes remote base url...
find_git_configs ~/ "sed -i.bak s/dumbname.com/bettername.com/g"
