The Problem Tried to install the latest version of cpan and got stuck. Tracked it down to the dependency module Mac::SystemDirectory which was failing to build:

The Solution Use the MacOS installer command to deploy the needed files:
|
|
sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target / installer: Package name is macOS_SDK_headers_for_macOS_10.14 installer: Installing at base path / installer: The install was successful. |
The, rerunning the cpan install works:
|

Sonos was running just fine oon my MacOS Mojave iMac, then I had to force-quit it due to a system freeze. The Sonos app REFUSED to start, no matter what I tried, including uninstall/reinstall, full scrub of all files located, uninstaller software, reboots, cache cleaning and reboot with Onyx – NOTHING worked, and i was […]

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:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 |
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 […]

I have a task in Perl to list specific files based on pattern match, those with and those without the string “_from_”. There are two files in the directory to filter: static-east.properties static-east_from_west.properties To capture the files with the _from_ string was easy:
|
|
/^static-(.*?)_from_(.*?)\.properties$/ |
To capture the files WITHOUT the _from_ string was not quite […]

I use csshX on a daily basis. The default layout on my screen for three nodes is one column with three rows, one per node. This layout is excellent for visual positioning, but does make it harder to read long output. For this purpose, I start csshX using the column quantity specifier -x and I […]

I was getting rsync errors from one source host:
|
|
Corrupted MAC on input. Disconnecting: Packet corrupt |
Finally tracked it down to the application “Little Snitch”. Needed to fully uninstall it and reboot to get the problem solved.

Problem: Trying to run a yum -y update as root aborts with the following error:
|
|
The GPG keys listed for the "Percona-Release YUM repository - x86_64" repository are already installed but they are not correct for this package. Check that the correct key URLs are configured for this repository. Failing package is: sysbench-1.0.17-2.el6.x86_64 GPG Keys are configured as: file:///etc/pki/rpm-gpg/RPM-GPG-KEY-Percona |
The solution, found on the Percona website, is this: sudo yum update percona-release Source URL: https://www.percona.com/blog/2019/02/05/new-percona-package-signing-key-requires-update-on-rhel-and-centos/
