Added new script for warnings in chutney's logs
In chutney's repository in the TODO file there was a comment about doing a script for getting warnings in the logs. The script is at https://github.com/huig-/chutney and i made a pull request days ago (see https://trac.torproject.org/projects/tor/ticket/13956#ticket) with a different change but now it also includes the script about warnings. The script basically gets warnings int net/nodes/*/info.logs and counts how many times each warning occurs. I have also added an option to get the warnings of only one node (specified by the user) instead of all of them.
The script is called warnings.sh
