Automating exporting packet dissections using tshark

Question

I am trying to automate the exporting of full dissections of a pcap to a .txt file using tshark. I am aware of the file->export packet dissections as option, but I am working to automate that. Right now I have tshark -X lua_script: -r > . The files enclosed in <> are paths. The lone > is the command for printing text. It will export packet summaries but not the full dissection. IS there any way to export the full dissection to the command line. These sample line are what is exported right now,

1 0.000000000 02:00:00:00:00:67 -> IPv4mcast_01:05:ee 0x8903 1467 Data Center Ethernet (DCE) protocol(Cisco)

This is what I want the exports to look like

Note: this is what the packet dissections look like when using file->export packet dissections

Thank you in advance!

After looking at the problem I have figured it out. It is tshark -X lua_script:filename -r p.pcap -V -T text > file.txt.

The key was the -V, as that prints packet details.
