Using variables in tshark filter in shell script -


i'm trying write shell script applies tshark filter on pcap file. filter variable characters '/'.

i have like

tshark -r $file -y "frame contains $pattern"

which works filters without '/'. once $pattern contains '/', there error saying tshark: '/' unexpected.

how write script such variable pattern can contain special characters?

try quoting pattern, example:

tshark -r $file -y 'frame contains "$pattern"'

on windows, use:

tshark.exe -r $file -y "frame contains \"$pattern\""
