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`

Open cmd with admin privileges with awk binary on same folder (awk 3.0.3) :
setup-x86_64.exe -P awk 'NR==1{printf $1}{printf ",%s", $1}' packagelist``

Doesn't work... setup-x86_64 installer launches normally...

It works great in cygwin console not windows cmd.

perhaps a bit clearer:
cygcheck -c -d | sed "1,2d" | cut -d' ' -f1 > package list

I finally got this to work but it took me a while to find out - by combining the initial description with tkimva's comment:

  1. Do an export on the machine that already has all packages installed you want on the new machine, using the cygcheck command from the description at the top and creating the file packagelist.
  2. Download the cygwin installer to an install directory on the new machine, copy the file packagelist from the old machine into the same directory.
  3. Do a minimum installation of cygwin on the new machine as a Windows admin, i.e. just run the cygwin setup program, skip the package selection part, and finish the installation.
  4. Open a cygwin console as Windows admin, navigate to the cygwin install directory.
  5. Run the "./setup-x86_64 -P `awk..." command from the description at the top. This will launch the cygwin setup as normal but instead of showing the usual package selection step you will find the list imported from packagelist, which you can confirm and install.

perhaps a bit clearer:
cygcheck -c -d | sed "1,2d" | cut -d' ' -f1 > package list

Even sed is unneeded here. Compact and clean:
cygcheck -cd | tail -n+3 | cut -d' ' -f1 > packagelist

Note, that "-P" expects a comma separated string with packages. If you have a lot of packages, this list can become too large for the terminal. If thats the case, you need to do some heuristic and split the packagelist file into two or more files. Then run the installer on each of these files.

@patrikarlos's solution worked for me. In my case, the list was too long and I had to split it into multiple files and run the command above one by one.

@RKirchnerNL's explanation worked for me.

I am not savvy with awk, so I found tr to work, too. Also, if the package list is short enough, the single comma-separated list of packages can be created on the source computer so destination computer does not need a pre-installed bare-bones Cygwin in order to assemble such a list:

cygcheck -cd | tail -n+3 | cut -d' ' -f1  | tr '\n' ',' | sed -e s=,$== | tee ~/tmp/PackageList.txt
_autorebase,adwaita-icon-theme,adwaita-themes,alternatives,<...snip...>,xwin-xdg-menu,xwinclip,xwininfo,xxd,xz,zip,zlib0,zstd

This needs to be modified into a *.cmd file by prefixing the single-line comma-separated list with .\setup-x86_64.exe -P .

Just be aware that if you copy the file to a *.cmd file before prefixing the line, Windows 10 will "protect" you from running the file (even though you may select Edit from the context menu). You need to open Notepad first, then load the file.

cygcheck -c -d | sed -e "1,2d" -e 's/ .*\$//' | awk '{print $1}' | sed -e ':a' -e 'N' -e '$!ba' -e 's/\n/,/g'  > cygwin_list.txt

and after that on another Windows create bat file with:

setup-x86_64.exe -P _autorebase,adwaita-icon-theme,alternatives,archivemail,... etc full last list.

It's enough to do:

cygcheck -cdn

None of this sed'ding, bro.
