You need to put the filter in quotes so that the OS sees it as
one word:
tshark -f "`cat /path/to/my_filter`"
should do the trick. Just tried it myself:
sablo@for-gods-sake ~
$ cat filter
host 10.31.103.64 or
host 10.31.100.254
sablo@for-gods-sake ~
$ tshark -f `cat filter`
tshark: Capture filters were specified both with "-f" and with additional command-line arguments
sablo@for-gods-sake ~
$ tshark -f "`cat filter`"
Capturing on eth0
0 packets captured
sablo@for-gods-sake ~
$
Hope this helps, cheers,
