# 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.
