I am using the below command but while running the command in linux, getting the below error.
sed -n \'/^[2015/01/01 03:46/,/^[2015/01/01 03:47/p\' < Inpu
You need to escape the [, or else it thinks its start of a group, and escape to / in your data.
[
/
sed -n '/^\[2015\/01\/01 03:46/,/^\[2015\/01\/01 03:47/p' Input.txt
or (thanks to nu11p01n73R)
sed -n '\|^\[2015/01/01 03:46|,\|^\[2015/01/01 03:47|p' Input.txt
