+# Create A Filename With The Current Date
+
+I was recently working on a script to pull a scrubbed database dump using the
+`pg_dump` Postgres utility. Ultimately, the script does something like this to
+dump a remote database to a local file:
+
+```bash
+pg_dump \
+  -h host.region.rds.amazonaws.com \
+  -U db_username \
+  -d db_name \
+  -F c \
+  -f scrubbed-database-$(date +%Y-%m-%d).dump
+```
+
+Notice the last part of that command where we define the name of the dump file.
+It has a `$(...)` that is used to run and interpolate a command as part of the
+filename.
+
+Here is that `date` command run on its own:
+
+```bash
+$ date +%Y-%m-%d
+2025-04-02
+```
+
+In the above command, that would mean if I were to run it today, I'd get
+`scrubbed-database-2025-04-02.dump`.
+
+This approach can be used with any command where you are producing a file that
+you want to be dated or timestamped.
+
+Here is another example that incorporates the time as well:
+
+```bash
+$ touch $(date +%Y%m%d_%H%M%S)-migration.sql
+# => 20250402_092442-migration.sql
+```

+# Bypass On-Save Tooling When Writing File
+
+Every once in a while I run into an issue where my code formatters or linters
+are misconfigured for a project. I try to save a file and it applies formatting
+that I don't want. Or in an extreme case, the error ouput of the tool is what
+overwrites the file.
+
+I need to troubleshoot my dev tooling eventually, but I don't want to get
+sidetracked at the moment. I just want to save the file. What can I do?
+
+Tools like linters and code formatters are typically hooked up to Vim via
+autocommands on certain actions like `FileWrite*` or `BufWrite*`. We can
+execute a Vim command like writing a file (`w`) while disregarding autocommands
+like so:
+
+```vim
+:noautocmd w
+```
+
+or, write and quit:
+
+```vim
+:noautocmd wq
+```
+
+This disables all autocommands for this one command. The file gets saved and
+the misconfigured formatters and linters don't clobber the changes you
+intended.
+
+See `:h noautocmd` for more details.
