Pass a Command Line Argument to an Alias

Ever want to pass in a command line argument to an alias? You would think you could just do it with $1, but actually you have to create a function and then call that function. So, for instance if you want to pass a portion of a log file name, you could set your alias like this…

alias catlog='function _catIt() { cat /var/logs/$1.log; };_catIt'

then, when you want to see the XX00D log, you just call your alias like so…

catlog XX00D

Checking and Maintaining Linux Disk Space

Ever need to find out what’s using the most space on your Linux box? There are a couple commands that will help make things easier…

To find out how much space you have use:

df -h .

Which will give you output like so…

Filesystem      Size  Used Avail Use% Mounted on
/dev/sda         20G   15G  4.2G  79% /

To list out the directories using the most space, use this handy command…

sudo du /usr/local | sort -n

… where /usr/local is the directory you want info for (you can also just start from root: /)
