# There was a day where I have too many color schemes in iTerm2 and I want to remove them all. | |
# iTerm2 doesn't have "bulk remove" and it was literally painful to delete them one-by-one. | |
# iTerm2 save it's preference in ~/Library/Preferences/com.googlecode.iterm2.plist in a binary format | |
# What you need to do is basically copy that somewhere, convert to xml and remove color schemes in the xml files. | |
$ cd /tmp/ | |
$ cp ~/Library/Preferences/com.googlecode.iterm2.plist . | |
$ plutil -convert xml1 com.googlecode.iterm2.plist | |
