Execute a command for every line in a file in bash

Another very handy bash snippet:

cat nodesToConsider.txt | while read in; do cp ../'layer0_inputGuess_n'$in'.png' .; done

We exist. We google. We bang heads.

I started this blog (originally called 'undergraduatebioinformaticist', hence the 'we exist' in the tagline above) because in my years of UROP-ing at a bioinformatics facility at MIT, I realized just how hard it is to glean free knowledge about this rather caffeinated field. I put hard effort into deciphering what I know from online forums and patchy documentation. I'm jolly well going to share it.

Post-MIT, I had a year-long stint at a tech company in Silicon Valley, and now I'm pursuing a PhD at Stanford.
