|
|||
|
|
|
|||
|
|
> changes file-extension based on mime-type
|
|||
|
|
|
|||
|
|
### also
|
|||
|
|
|
|||
|
|
- removes `*?|^:"<>` characters from the file-name
|
|||
|
|
- reducing multiple spaces, dots, and underscores
|
|||
|
|
- adds rename-date suffix to ensure uniquness of the filename
|
|||
|
|
- strips exec-flag from non-executive types (usual leftover from FAT/NTFS)
|
|||
|
|
- optimizes images while at it (shows reduction size in `kb` and `%`)

## install
|
|||
|
|
|
|||
|
|
1. look at [install](./install.sh) file for instructions
|
|||
|
|
2. adjust `PREFIX` at wish
|
|||
|
|
3. make sure the final directory is on `$PATH`
|
|||
|
|
|
|||
|
|
|
|||
|
|
## use
|
|||
|
|
|
|||
|
|
`rename-ext /Data/Pictures/_unsorted/**/*`
|
|||
|
|
|
|||
|
|
to only change extension and nothing else:
|
|||
|
|
|
|||
|
|
`rename-ext --only-ext /Data/Photos/2020/*`
|
|||
|
|
|
|||
|
|
to only print a report:
|
|||
|
|
|
|||
|
|
`rename-ext --test-run /Data/Docs/_dump/*`
|
|||
|
|
|
|||
|

## q&a
|
|||
|
|
|
|||
|
|
**Q**: why not just rename files to hashes of their contents, and store original filenames in some database?
|
|||
|
|
|
|||
|
|
**A**: good point. that database is in my case a filesystem itself.
