Import/Export Cygwin List of installed packages

Import & Export Cygwin List of installed Packages

If you want to go from 32 to 64 bit Cygwin but keep all the packages[1], you might find yourself in a spot where you would like to export the list of cygwin packages and also be able to install cygwin with all these packages again. I will tell you how. Open your Cygwin shell and enter

cygcheck -c -d | sed -e "1,2d" -e 's/ .*\$//' > packagelist

This will simply dump a list of installed packages. To install Cygwin 64 with these packages selected, download setup-x86_64[2] and execute it with the command line parameters

./setup-x86_64 -P `awk 'NR==1{printf \$1}{printf ",%s", \$1}' packagelist`

Take a list of CIDR address blocks and combine them, for example, and gives I usually use "list-iana-reserved-ranges | aggregate-cidr-addresses" to get a list of blocks to not report with firewall log processing.

Execute the given command in a way that works safely with cron. This should
typically be used inside of a cron job definition like so:

Instructions on how to fix npm if you've installed Node through Homebrew on Mac OS X or Linuxbrew

READ THIS Very Important Update

This entire guide is based on an old version of Homebrew/Node and no longer applies. It was only ever intended to fix a specific error message which has since been fixed. I've kept it here for historical purposes, but it should no longer be used. Homebrew maintainers have fixed things and the options mentioned don't exist and won't work.

I still believe it is better to manually install npm separately since having a generic package manager maintain another package manager is a bad idea, but the instructions below don't explain how to do that.

Fixing npm On Mac OS X for Homebrew Users

Installing node through Homebrew can cause problems with npm for globally installed packages. To fix it quickly, use the solution below. An explanation is also included at the end of this document.
