My fav script to unpack anything, found a few years ago somewhere

      function ex() {

There did not seem to be an RCS story. Whether the device is RCS capable or not seems to be up to some unfathomable Google logic the tickling of which didn't work for me. Having old RCS chat histories and new RCS chats not work made me go back to stock quick.

There's a lot of better ways to do this. For starters, the sp script is bash. He could just edit the script. There's also a function for returning the metadata in machine-parseable syntax:

  function sp-metadata {
    # Prints the currently playing track in a parseable format.
  
    dbus-send                                                                   \
    --print-reply                                  `# We need the reply.`       \
    --dest=$SP_DEST                                                             \
    $SP_PATH                                                                    \
    org.freedesktop.DBus.Properties.Get                                         \
    string:"$SP_MEMB" string:'Metadata'                                         \
    | grep -Ev "^method"                           `# Ignore the first line.`   \
    | grep -Eo '("(.*)")|(\b[0-9][a-zA-Z0-9.]*\b)' `# Filter interesting fiels.`\
    | sed -E '2~2 a|'                              `# Mark odd fields.`         \
    | tr -d '\n'                                   `# Remove all newlines.`     \
    | sed -E 's/\|/\n/g'                           `# Restore newlines.`        \
    | sed -E 's/(xesam:)|(mpris:)//'               `# Remove ns prefixes.`      \
    | sed -E 's/^"//'                              `# Strip leading...`         \
    | sed -E 's/"$//'                              `# ...and trailing quotes.`  \
    | sed -E 's/"+/|/'                             `# Regard "" as seperator.`  \
    | sed -E 's/ +/ /g'                            `# Merge consecutive spaces.`
  }

But as the other replier mentioned, the point was to show off an example of how text manipulation skills can solve many problems, not solve this specific problem in the best way possible.

TIL a neat way to add comments to continued shell lines. Thanks!

I keep a small series of patches for various software on my system, to fix, or at least relocate, config files to XDG locations[1]. I do this for applications I care about keeping their state. For other applications I either set the environment variables or remove the dirs on login[2]. Of course, the complexity of the project and my familiarity with the language also affects whether I bother with it. Not gonna be able to change ~/.cargo or ~/.dotnet soon (unless someone has patches for those?)

It's buried in my gentoo config, but I wonder if there'd be a good way to make this useful on other distros.

Regarding ~/.cargo (and other tools), I've had some success with following suggestions from https://github.com/b3nj5m1n/xdg-ninja
