## rename-ext
|
||
# > 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 `%`)
|
||
|
||
## example
|
||
# rename-ext /Data/Pictures/_unsorted/**/*
|
||
|
||
## requires
|
||
# - file - to determine file type
|
||
# - `cargo install sd` – better sed
