How to make tshark use \t as field separater, rather than default comma, when writing output to csv file?

Question

I have described the problem I face when tshark uses , as a field delimiter in this question when writing output to a .csv file.

So I'd like a way to instruct Tshark to use another character, say \t, as field separator.

The normal Tshark command is something like:

tshark -r inputFile.pcap -T fields -e fieldA -e fieldB -e fieldC > outputFile.csv

What do I add to this command to instruct tshark to use \t as field separator, while writing the output to .csv file, rather than the default ,?

Accepted Answer

As per the tshark manual or even built-in help; tshark -h:

  -E<fieldsoption>=<value> set options for output when -Tfields selected:
     bom=y|n               print a UTF-8 BOM
     header=y|n            switch headers on and off
     separator=/t|/s|<char> select tab, space, printable character as separator
     occurrence=f|l|a      print first, last or all occurrences of each field
     aggregator=,|/s|<char> select comma, space, printable character as
                       aggregator

so, use -E separator=/t, you might also want to consider adding quotes around fields, e.g. -E quote=d.
