vimdiff cheat sheet

##git mergetool

In the middle file (future merged file), you can navigate between conflicts with ]c and [c.

Choose which version you want to keep with :diffget //2 or :diffget //3 (the //2 and //3 are unique identifiers for the target/master copy and the merge/branch copy file names).

:diffupdate (to remove leftover spacing issues)

:only (once you’re done reviewing all conflicts, this shows only the middle/merged file)

PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

• -E: will describe the underlaying queries of the \ commands (cool for learning!)
• -l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)

Scripted Jenkins Plugins install

Jenkins has a very rich catalog of plugins and it's quite easy to install and update them via UI. BTW, when you want to add tons of plugin via UI, it's a fairly long and boring procedure.

Hopefully, mass installation (or update) could be easy using a simple bash script (curl/python required) :

Create a file containing plugins to be installed (or updated), ie iplugins :
