I am trying to identify a tab value in my sed command. I have tried \t but that doesn't work. I was trying \x09 as a hexidecimal search but I found that I must be formatting it incorrectly because no hex value will work. The format for the find part of my sed command is /\x09/ I hope someone who knows more about sed than I do (probably most of the world's population) can correct my sed expression. Thanks in advance.
