With options -e
, -n
, -p
, perl can do what grep/awk/sed can, what about ruby?
Let's take the result of ls -l
as input and process it with ruby
\ls -l | ruby -ne 'print if /^d/'
\ls -l | ruby -ne 'puts split(/\s+/).last if /^d/'
### MATPLOTLIBRC FORMAT | |
# This is a sample matplotlib configuration file - you can find a copy | |
# of it on your system in | |
# site-packages/matplotlib/mpl-data/matplotlibrc. If you edit it | |
# there, please note that it will be overridden in your next install. | |
# If you want to keep a permanent local copy that will not be | |
# over-written, place it in HOME/.matplotlib/matplotlibrc (unix/linux | |
# like systems) and C:\Documents and Settings\yourname\.matplotlib | |
# (win32 systems). |

One of my favorite past times is to look at the notebooks of famous scientists. Da Vinci's notebook is well known, but there plenty others. Worshipping Da Vinci like no other, I bought a Think/Create/Record journal, used it mostly to keep jot down random thoughts and take notes. This was great in the beginning, but the conformity of lines drove me nuts. Only moleskines made blank notebooks, so I had to buy one.
At the same time I started a freelance project. The project itself is irrelevant, but suffice to say it was very complex and spanned several months. It seemed like a perfect opportunity to use the moleskine. Looking back, all my entries fell under few categories:
##git mergetool
In the middle file (future merged file), you can navigate between conflicts with ]c
and [c
.
Choose which version you want to keep with :diffget //2
or :diffget //3
(the //2
and //3
are unique identifiers for the target/master copy and the merge/branch copy file names).
:diffupdate (to remove leftover spacing issues)
:only (once you’re done reviewing all conflicts, this shows only the middle/merged file)
