Sorting and removing duplicate words in a line

Question

The sort command lets me put lines in alphabetical order and remove duplicate lines. I need something similar that can sort the words on a single line, put them

Answer 1

All of the answers prior to this one can only sort a single line at time. The following can be used to pipe a whole list of such lines into and it will print the sorted list of unique words for each line.

awk '{ delete a; for (i=1; i<=NF; i++) a[$i]++; n=asorti(a, b); for (i=1; i<=n; i++) printf b[i]" "; print "" }'

Thanks @jaypai for a lot of the syntax used in this.

Example:

>cat file
group label wearable edit_group edit_group_order label_max camera_elevation camera_distance name label_min label_max value_min value_max camera_angle camera_elevation id
id group label wearable edit_group clothing_morph value_min value_max name value_default clothing_morph group
id label show_simple wearable name edit_group edit_group_order group clothing_morph clothing_morph camera_distance label_min label_max value_min value_max camera_distance camera_angle
id group label wearable name edit_group clothing_morph value_min value_max value_default
group label wearable id clothing_morph edit_group edit_group_order label_min label_max value_min value_max name camera_distance camera_angle camera_elevation
id group label wearable edit_group name label_min label_max value_min value_max wearable
name id group wearable edit_group id group wearable id group wearable id group wearable value_min value_max

>cat file | awk '{ delete a; for (i=1; i<=NF; i++) a[$i]++; n=asorti(a, b); for (i=1; i<=n; i++) printf b[i]" "; print "" }'
