I have mp4 files that have weird characters etc. in them.
To handle them, I used the following to convert them using xargs and avconv:
find *.mp4 -print0|sed 's/mp4//g'|xargs -0 -I {} avconv -i {}mp4 {}mp3

635. Installing R on Rocks 5.4.3
Rocks 5.4.3 is based on CentOS 5.6 which is practically ancient by now (released Jan 2011).
Either way, when dealing with someone else's cluster its better to not fiddle too much with what is already working.
Here's a not at all elegant way of install R on Rocks 5.4.3

634. Compiling EQ3/6 on Debian
EQ3/6, a program for calculation of geochemical equilibrium in aqueous systems and which can be downloaded here, has a spectacularly unhelpful Install.txt file.
Here I describe how I went about to compile it.
1. Download EQ36_80a_linux.zip from https://www-gs.llnl.gov/about/energy-security/geochemistry
2. Extract it. Move the EQ3_6v8.0a folder to ~
You can put it wherever you want, but then need to edit eq36cfg, and you'll have to deal with csh not handling long paths that well. It's just easier to give up and put EQ3_6v8.0a under $HOME
3. Time to extract further, compile and set up
Time to look at what we have. There are .f files in
A lot of these are subroutines. We'll compile all files as modules and make static libraries
You should now have a bin/ that looks like
4. Test
I reran as
and compared
The results are the same.We're good.
Everything put together as a script:
Sadly, we do not provide specific instructions on how to compile and link the software to build the executables. You have to figure that out yourself for your specific platform. It will require some number of steps. Also, we do not provide makefiles. It is not necessary to use make files, although some people like them. If all this seems to exceed your knowledge and capacity, seek the assistance of a qualified Linux or Unix maven who knows how to do these things on your platform.
