How to create a command like :sync_sub in lf?

[LinArcX]

Hi.

Imaine i have a video called:
House.of.the.Dragon.S01E01.WEB.1080p.x265.HEVC.mkv

And also I have a subtitle:
House.of.the.Dragon.S01E01.WEB.1080p.x265.HEVC.srt

The problem is that, subtitle isn't synced with video, so I'm using alass to make it sync like this:

alass House.of.the.Dragon.S01E01.WEB.1080p.x265.HEVC.mkv House.of.the.Dragon.S01E01.WEB.1080p.x265.HEVC.srt output.srt

I want to automate this process using lf. for example, I want select both video and unsynced subtitle, run a command like :sync_sub in lf and the command that you saw earlier should be run in the background.

Also at the end, I want to:

1. rename: House.of.the.Dragon.S01E01.WEB.1080p.x265.HEVC.srt to House.of.the.Dragon.S01E01.WEB.1080p.x265.HEVC.srt_

2. rename: output.srt to House.of.the.Dragon.S01E01.WEB.1080p.x265.HEVC.srt

Any idea?

Maybe this:

cmd sync_sub ${{
	srt="$(echo "$fx" | grep '.srt')"
	mov="$(echo "$fx" | grep -v '.srt')"
	alass "$mov" "$srt" "output.srt"
	mv "$srt" "$srt.bak"
	mv "output.srt" "${mov%.*}.srt"
}}

You would need to have movie and srt file selected before giving command

I can't. Because this is IDEA not Q/A.
