I’ve been desperately trying to create more time, and naturally I decided to do an analysis of, among other things, how I spend my time on the terminal… the premise here being that automation will inevitably result in more time. It’s mad I know, but that’s what desperate people do –they do crazy things. I increased buffer size for history file on three (3) machines I access frequently, got frequencies of top 20 commands across all machines and have thus began automating candidate tasks.
I put the entries below in my .bashrc file and took note of the top 20 commands I used the most in the last 24 hours (see plot)
# persist history commands export HISTCONTROL=ignoredups:erasedups # duplicate entries export HISTSIZE=100000 # history size export HISTFILESIZE=100000 # history size shopt -s histappend # append to history export HISTTIMEFORMAT="%d/%m/%y %T " # Save and reload the history after each command finishes export PROMPT_COMMAND="history -a; history -c; history -r; $PROMPT_COMMAND"
Here’s what I’ve done so far…
R, latex& dvipdf
I ditched R base graphics for ggplot2 and it takes insanely long; that coupled with the ‘latex -> dvipdf’ cycles to get output pdf file made these commands prime candidates for automation… so I created the make file below.
phiri-thesis.pdf : phiri-thesis.dvi dvipdf phiri-thesis.dvi phiri-thesis.dvi : phiri-thesis.tex latex phiri-thesis.tex phiri-thesis.tex : phiri-thesis.bib latex phiri-thesis.tex bibtex phiri-thesis latex phiri-thesis.tex
ssh, git, sudo
ssh: Periodic ‘write failed: Broken pipe’ meant re-executing ssh commands everytime connection broke; so I put a ‘ClientAliveInterval 120’ entry in /etc/ssh/ssh_config
git: I push, fetch and pull periodically; connection to my github account especially takes long –I’ve a script that does this automatically now
sudo: I made changes via ‘visudo’ to stop myself from issuing sudo everytime I needed superuser previlleges for certain commands..
I’ll replicate this for a whole week so I have a comprehensive picture of what else I can automate…
