Block cmd w from closing xterm window on mac

After doing this at least twice in 24 hours I thought I better sort this out. You can block cmd w (close window) and assign it to something else to stop this from happening.

Goto System Preferences -> Keyboard -> Keyborad Shortcuts -> Application Shortcuts

Then Add (+)

Application = X11.app
Window = Close
Shortcut = Whatever you want I use cmd+shift+w

Danke.

Creating An RPM for openSUSE - some notes

I wanted to create an rpm which I had not done before. Here are some notes on the process.

I created a user on my machine for this process called rpmbuilder.  

Create a folder for development and create the layout for developing rpms

mkdir rpmdevenv; cd rpmdevenv

mkdir BUILD RPMS SOURCES SPECS SRPMS

Create the file ~/.rpmmacros with

%packager       High Fructose Corn Syrup

%_topdir        /home/rpmbuilder/rpmdevenv

%_rpmtopdir     %{_topdir}

%_builddir      %{_rpmtopdir}/BUILD

%_rpmdir        %{_rpmtopdir}/RPMS

%_sourcedir     %{_rpmtopdir}/SOURCES

%_specdir       %{_rpmtopdir}/SPECS

%_srcrpmdir     %{_rpmtopdir}/SRPMS

Add source code to SOURCES

Add .spec file to SPECS

Build the rpm from the SPEC

rpmbuild -ba SPECS/something.spec

Returning the HTTP code of a HTTP request

This is really useful for returning HTTP code of a request.

curl --write-out "%{http_code}\n" --silent --output /dev/null www.example.com

Find all unique url's from Apache log files

I needed to build a list of all unique hits that had been made on a website in Apache.

Here's what I came up with using awk and sed.  This should match any HTTP 2xx or 3xx requests and strip of any GET request parameters.


awk '$9 ~/^(2|3)/ {print $7}' somelogs* | sed 's/\?.*$//' | sort | uniq

Global search and replace with sed

So today I needed to replace a few hundred href link in varying content today.  Here's my take on solving it. This works in zsh.  I think for bash you need to add the do and done parts of the for loop, i'm not sure.

for file in `grep -lR "href=\"\/static\/" .`; sudo sed -i -e 's/href=\"\/static\//href=\"\/applications\/static\//g' $file

SSH Pseudo terminals

There is always so much more to SSH than I know about.  Here is another discovery I made today.  This allows me to ssh into a machine via a gateway in just one command care of the -t flag

ssh -t agatewaymachine.com "ssh 192.168.1.253"

Disable php deprecation warnings per apache virtual host

php_value error_reporting 6135

Seems you have to use the numerical value in apache for this.  This should be all E_ALL minus E_DEPRECATED AND E_USER_DEPRECATED

This will only work if the error handling function is not overridden in the php code.
