Full Discussion: Change in last line of each part of a file

Elixir_sinari's suggestion is definitely the most fool proof, but is it accurate to say if the last field equals "st_cd;" or "dvr_id;", then change 344 to 344\\006:

Code:
#!/bin/ksh
 
awk ' {
   if(($NF == "st_cd;") || ($NF == "dvr_id;") )
      gsub("344", "344\\006")
   print $0
} ' input.txt
