## Git clean up

```sh
# Delete untracked
git clean -fdx

git gc
```

## Delete `.DS_Store`

With [find](https://stackoverflow.com/q/30483670):

```sh
find . -name ".DS_Store" -print -type f -delete
```

With [fd](https://github.com/sharkdp/fd):

```sh
fd -H '^\.DS_Store$' -tf -X rm
```

## [sd](https://github.com/chmln/sd)

Remove proto options:

```sh
sd -F 'import "validate/validate.proto";' '' api/raw/*.proto
sd -F 'import "marshal-zap.proto";' '' api/raw/*.proto
sd -f s '\s\[.*?];' ';' api/raw/*.proto
```

## [fdupes](https://github.com/adrianlopezroche/fdupes)

Remove duplicated files:

```sh
fdupes -rdN .
```

## [rsync](https://github.com/WayneD/rsync)

```sh
# Result is dst/src
rsync -avzP src dst

# Result is dst/* with * is from src
rsync -avzP src/ dst
```

Commonly flags:

- `-v`: verbose
- `-z`: compress
- `-P`: enable both `--partial`, `--progress` to easily resume after interupt
- `-n`: dry run

Be careful flags (need dry run if not sure):

- `-u`: skip if files in **dst** is already newer than in **src**, if you want
  to sync both ways
- `--delete`: delete files in **dst** if not exist in **src**, useful to sync
  dst with src

## [atuin](https://github.com/atuinsh/atuin)

Remove duplicated command:

```sql
delete
from history
where id not in (select max(id)
                 from history
                 group by command);

delete
from history
where length(command) > 128;
```

Remove shell history:

```sh
cat /dev/null > ~/.zsh_history
```

## [F2](https://github.com/ayoisaiah/f2)

Rename:

```sh
# If want dry run, remove -x
f2 -r "{mtime.YYYY}{mtime.MM}{mtime.DD}.{mtime.H}{mtime.mm}{mtime.ss}{ext}" -F -x
```

## [Instaloader](https://github.com/instaloader/instaloader)

`args.txt`:

```txt
--no-video-thumbnails
--no-captions
--no-metadata-json
--stories
--fast-update
--sanitize-paths
--abort-on=302,400,429
--no-iphone
```

`login.txt`:

```txt
--login=your_insta_username
--sessionfile=where/sessionfile/store
```

Run:

```txt
instaloader +login.txt +args.txt +targets.txt
```

## [gRPCurl](https://github.com/fullstorydev/grpcurl)

```sh
grpcurl -proto path/file.proto \
    -d '{"key": "value", "timestamp": "1997-04-01T00:00:00Z"}' \
    internal-social.zalopay.vn:443 \
    pkg.Service/GetData
```
