repotrack and repoquery -commands to resolve dependencies.

2014-12-18 1 min read Fedora

To get all the depencies of a package, you can try:

repoquery -a --requires --resolve 

Example output:
glibc-0:2.20-5.fc21.i686
bash-0:4.3.30-2.fc21.x86_64
chkconfig-0:1.3.63-1.fc21.x86_64
glibc-0:2.20-5.fc21.x86_64
openssl-libs-1:1.0.1j-1.fc21.x86_64

and then to query in nice tree format, you can use :

repoquery -a --tree-requires PACKAGE_NAME

And finally use that with repotrack:

repotrack -a x86_64 -p . $(repoquery --qf=%{name} -g --list --grouppkgs=all 'Office Suite and Productivity' |tr '\n' ' '
)

Now for the fun part, why use all the above when you can simply use:

yumdownloader --resolve 

So, if you have reached this line then you don't need repotrack/repoquery, simply use yumdownloader :)

PHP Image gallery with fancybox.

2014-12-09 1 min read Photo Uncategorized

So, I was looking for some quick to setup PHP Image gallery file. I found couple but none of them suited my needs too well. So I had to write my own.

Very simple PHP script to show all the images under ‘images’ folder.

Shows some details in the images.

That is all that I wanted and that is all that this script does. So pretty simple single php file. Dependency is on fancybox so you will need the jquery and all but nothing else is required.

Search CVE – web interface with php

2014-11-03 1 min read Uncategorized

So, last few weeks have been very busy with lot of security issues, so I thought of having a local CVE Search app. But all I could find on google and github.com were on python and nothing that I could use quickly. So here is link to one that I wrote quickly:
