Special characters not working with grep

[jjun3188]

When I try grep with any special character,
eg. cw tail -pprod /aws/lambda/some-app-name -b10m --grep [email protected]

I get the error below:
Invalid filter pattern

It works fine if I remove special characters, but even -g and --grep="" did not work with special characters.

I also tried escaping special characters using /, //, \ and \\, but no luck.

Is it something that I am doing wrong?
I couldn't find related documentation or issues in this GitHub page.

Hi @jjun3188

This is the supported syntax:
https://docs.aws.amazon.com/AmazonCloudWatch/latest/logs/FilterAndPatternSyntax.html

Have you tried double quotes?
--grep="[email protected]"

I tried --grep="[email protected]" as well. same error..
Also, forgot to mention that I am using MacOS

Hello @jjun3188

I just released a new version with an upgrade to the V2 of the AWS SDK.
Can you test again and see if the problem is solved?

Same problem here.

Version: 4.1.0
SO: MacOS

In my case, I need to use / char.
Tried without escape and with escape (\/).
And tried with and without quotes and double-quotes.

The error message is the same for all attempts:

operation error CloudWatch Logs: FilterLogEvents, https response error StatusCode: 400, RequestID: e55cdea4-8b02-45c8-b350-fc08c0e2e9ce, InvalidParameterException: Invalid filter pattern

It worked by using the following pattern:

--grep '"GET my/resource/foo"'
