I have a base ~/.bash_aliases file
which I normally use Ansible to update on various servers when needed and thought I’d share it.
This is intended for sys admins using Ubuntu.
The main aliases are :
ll – I use this ALL the time, it’s `ls -aslch` and shows the file listing.
agu – Apt get update, just refreshes the apt files from the net, doesn’t actually install anything but should be run before running any apt programs.
agg – Apt Get Upgrade this updates all the programs that need upgrading. Usually the server needs to be restarted after.
acs – Apt Cache Search. If there’s something to install like the PHP gearman extension I’ll usually use `acs php | grep gearman` to work out the name.
a2r – Apache2 reload.
a2rr – Apache2 restart, for when just reloading the config isn’t enough.
aliasd – Open up the local aliases file. Will apply the changes when you exit nano.
aliasd_base – Open up the main (base) aliases file which contains these aliases. If not using Ansible then I normally load the aliases into a new server by pasting the contents of the file in on the command line, then running
aliasd_base and pasting it in again into the file.
chownWWW – Change the file and folder contents to being owned by www-data:www-data DO NOT RUN THIS IN THE ROOT DIRECTORY.
du – Directory usage. A general listing of file and directory sizes.
das – A directory size listing ordered by largest at the top. It’s not amazing but works well enough. I use `ncdu` the program (usually has to be installed with `agi ncdu`) to get better directory listing.
directoryExec – Makes the directories executable by the user and group.
logs – Shows most of the /var/log files, tails them so you can see any changes.
logsudo – Same as logs, but with sudo so you see more of the files.
gac – Git add and git commit. A nice quick way of doing a git commit. I usually do `gac -m “* Commit message here”
gitt – Shows the last 24hrs worth of git commits. Great for putting into a timesheet.
gittt – Shows how long ago the commits were, I mainly use this when trying to work out which commits are from today vs yesterday.
ssh-config – Edit the main ssh config file.
diglookup – Does a quick check of the A records, MX, TXT and other stuff for a domain, useful when someone says that there’s an issue with the site. example usage `diglookup kublermdk.com`
Note that the attempt to do a reverse lookup on the IP usually fails if there’s multiple A records for the main site, so you sometimes have to [ctrl] + [c] cancel out of that bit at the end. I’ll fix it one day :P
$ diglookup kublermdk.com

I then have a ~/.bash_aliases_local file that has server specific changes. e.g kublermdk-logs which will show the logs specific for my site, esp if it’s something like a Symfony project where a lot of the useful log files are stored in something specific. I’d have
alias kublermdk-logs='tail -f /var/logs/apache2/kublermdk/*.log /var/www/kublermdk/www/app/logs/*.log'
Grab what you want, let me know if you’ve got any good aliases yourself.
