I wanted to empty the time series data cache from the Prometheus server to start clean. The best practice is to use the administrative HTTP API via curl. For example, to clear all data for job mysqld as defined in the prometheus.yml configuration file:
curl - X POST - g 'http://localhost:9090/api/v1/admin/tsdb/delete_series?match[]={job="mysqld"}'
If you want to delete ALL data from Prometheus, then […]

Quickref: How to Remove a file from the staging area
git rm -- cached { fileName ( s ) }
The Story Recently, I accidentally added some files to git’s pre-commit phase, i.e.:
shell > git status
On branch master
Your branch is up - to - date with 'origin/master' .
Changes to be committed :
( use "git reset HEAD <file>..." to unstage )
new file : good1 . xml
new file : good2 . xml
new file : bad1 . xml
new file : bad2 . xml
modified : good3 . xml
modified : bad3 . xml
For example, here is how to handle the above situation:

3

shell > git rm -- cached bad1 . xml bad2 . xml bad3 . xml
shell > git status
On branch master
Your branch is up - to - date with 'origin/master' .
Changes to be committed :
( use "git reset HEAD <file>..." to unstage )
new file : good1 . xml
new file : good2 . xml
modified : good3 . xml
Untracked files :
( use "git add <file>..." to include in what will be committed )
bad1 . xml
bad2 . xml
bad3 . xml
To better understand, here are the phases/states/stages that git uses: Untracked – when a file is first created, git […]

To remove a specific package without its dependencies use rpm:
rpm - qa | grep pecl
rpm - e -- nodeps php55 - pecl - jsonc php55 - pecl - jsonc - devel
As always, YMMV!

In Terminal:
sudo mv / Library / Preferences / SystemConfiguration / com . apple . network . eapolclient . configuration . plist / Library / Preferences / SystemConfiguration / com . apple . network . eapolclient . configuration . plist . good
Then reboot. YMMV… This is why I am so upset with Apple these days – they constantly “dumb-down” MacOSX, removing features to “protect” the innocent public from harming themselves with the click of a mouse. Perfectly reasonable advanced features that existed in 10.6.8 are no-where to be found in 10.7 Lion (bad) […]
