I don't think field names have leading or trailing spaces, at least they're not intended to have them.
Info that might help:
Using tshark -G fields outputs a list of all fields and protocols in the application in a tab separated format.
Items may have info about Protocols (initial char is "P") or Fields (initial char is "F").
Protocol items have 3 elements; a type indicator ("P"), a text name and a filter name.
Field items have 9 elements: a type indicator ("F"), a text name, a filter name, the field type, the protocol associated with the field, the base for the field value, the bit mask for active bits in the field value and a comment for the field.
And now how I tested:
Post-processing the output of tshark -G fields with PowerShell showed no Fields or Protocols have a name element that has leading or trailing spaces.
tshark -G fields | `
ConvertFrom-Csv -Delimiter "`t" -Header "FieldInd", "Name", "FilterName", "FieldType", "Protocol", "Base", "Bits", "Comment" | `
Where-Object { $_.Name -match "^ +.* +$" }
and
tshark -G fields | `
ConvertFrom-Csv -Delimiter "`t" -Header "FieldInd", "Name", "FilterName" | `
Where-Object { $_.Name -match "^ +.* +$" }
What do you mean by "Key"?
Sample Keys are added. This below set of keys is not having any extra spaces at begin or at end
But there are keys with extra space at the start
Now In short my question is: Is there any chance that the below mentioned words come as a key along with an empty character at the beginning or at the end
I still don't understand the context and your terminology.
When you mention "key" do you mean a field name or value?
Yes its field name
Are you grabbing the data from output of
