I'm having some difficulty coming up with correct syntax to pull in specific host information for my slow query log file:
I'm using the following:
sudo pt-query-digest mysql-slow.log --since "2017-05-07 22:00:00" --until "2017-05-08 22:00:00" --filter ‘$event->{host} !~ m/^ip-1-1-1-1/’ > slow.log
In this scenario I'm trying to exclude all IPs that are 1.1.1.1. I can't figure out what's wrong.

To use this feature, you run pt-query-digest with the --review option. It will store the fingerprints and other information into the table you specify. Next time you run it with the same option, it will do the following: It won't show you queries you've already reviewed.
To disable or enable the slow query log or change the log file name at runtime, use the global slow_query_log and slow_query_log_file system variables. Set slow_query_log to 0 to disable the log or to 1 to enable it.
The minimum and default values of long_query_time are 0 and 10, respectively. The value can be specified to a resolution of microseconds. For logging to a file, times are written including the microseconds part.
Use ascii quote ('), not this non-ascii quote (‘);
Assuming that m/^ip-1-1-1-1/ works, it will catch both ip-1-1-1-1 and ip-1-1-1-123. So you may need something to terminate the ip. Perhaps m/^ip-1-1-1-1$/
Without hiding the arg in single-quotes, the shell is interpreting (at least) $event as a shell variable, {...} as something, and !~ as something.
