Not installing and running datawarrior550.tar_gz please help i want to run the program

file id tar_gz 
of datawarrior550 not unzipped with terminal command

unknown suffix  --ignored
ngs@NU-NGS:~/Downloads$ gunzip datawarrior550.tar_gz
gzip: datawarrior550.tar_gz: unknown suffix -- ignored

You have to rename this file to match its filetype.

For your case it should be datawarrior550.tar.gz and not datawarrior550.tar_gz. The gunzip application expects dot between tar and gz.

Also there is better one shot way - use tar command as follows:

tar -xf datawarrior550.tar.gz

Man-pages to read:

  • man gunzip locally or online
  • man tar locally or online
