Dropbox and dotfiles
I really like Dropbox. It's a convienient way to sync all your
computers without using rsync and what not. However, the thing that
bugs me the most is keeping my dotfiles in sync as I usualyl forget to
sync between computers when I change them. Thanksfully, Dropbox makes
this easier. 1. Create a directory in your Dropbox folder.
2. Move your dotfiles from $HOME to that folder. Change the prefix . with _.
3. Add this file (I named it dotfiler.sh, but you can name it whatever you want)#!/bin/sh for file in _* do ln -s -n -f `pwd`/$file $HOME/${file/#_/.} done
4. chmod +x the new file. (Currently, executable flag doesn't move
from one machine to another. So probably have to do this on each
machine.)
5. Run the file in your not dotfiles directory. This should keep all your dotfiles in sync whatever computer you are
using. If you also added .profile and .bashrc make sure that you take
your platform into account i.e., Linux, Mac OS X. Run the script whenever you add a new dotfile.Unix Job Control
Unix is a multitasking operating system (like most everyday operating systems nowadays) and as such it has and idea on how to do handle jobs. Jobs are executing which happen on a per shell basis as opposed to processes. Here is a summary of everything that you need to know about UNIX jobs.command &When running a command with an ampersand at the end for example "ls &" that job is put into the background and runs which you execute other commands on the shell.CTRL-cIf you want to kill a long running job press this combination to stop the job from running.CTRL-zSuspends a job, but does not kill it.bg %numIf you suspend a job and want to run it in the background (or you forgot to put a job in the background and put it in the background) run this.fg %numRun this to bring to front a background job or to run a suspended job in the foreground.kill %numKills a job number.jobsList all the active jobs on the shell. There can be multiple jobs with many running in the background.set notifyNotifies immediately on the shell if there is change in the a background job. -
