HPR3071: Bash snippet - quotes inside quoted strings
May 11, 2020 00:00 - 7.18 MBBash and quoted strings An issue I just hit in Bash was that I had a quoted string, and I wanted to enclose it in quotes. How to do this? This is the umpteenth time I have stumbled over this issue, and I realised I had found out how to solve it a while back but the information hadn’t rooted itself into my mind! I have always been less clear in my mind about quoted strings in Bash than I should be, so, assuming others might have similar confusion I thought I’d try and clarify things in the...
HPR3070: making vim xdg compatible

Once that is loaded, you should source the following file after "nocompatible" " file: ~/.config/vim/xdg.vim if empty($XDG_CACHE_HOME) let $XDG_CACHE_HOME=$HOME."/.cache" endif if empty($XDG_CONFIG_HOME) let $XDG_CON...
