Simply add it to your ~/.bash_profile
MAC OSX doesn't come with a locate command, This will do the same thing as the locate command on a typical Linux OS.
Simply add it to your ~/.bash_profile

Grabs the ip2location site and removes everything but the span tag containing the country value. Place it inside your .bashrc or .bash_aliases file.
Finds all cert files on a server and lists them, finding out, which one is a symbolic link and which is true.
You want to do this when a certificate expires and you want to know which files to substitute with the new cert.
To start, you first need to make sure updatedb has been run/updatedb, and initialized the db:
su -l root -c updatedb
This locate command is provided through the mlocate package, installed by default on most GNU/Linux distributions. It's available on the BSDs as well. Not sure about support for proprietary UNIX systems. The output is self-explanatory- it provides an overview of how many directories and files are on your system.
Catches .swp, .swo, .swn, etc.
If you have access to lsof, it'll give you more compressed output and show you the associated terminals (e.g., pts/5, which you could then use 'w' to figure out where it's originating from): lsof | grep '\.sw.$'
If you have swp files turned off, you can do something like: ps x | grep '[g,v]im', but it won't tell you about files open in buffers, via :e [file].
The wherepath function will search all the directories in your PATH and print a unique list of locations in the order they are first found in the PATH. (PATH often has redundant entries.) It will automatically use your 'ls' alias if you have one or you can hardcode your favorite 'ls' options in the function to get a long listing or color output for example.
'whereis' only searches certain fixed locations.
'which -a' searches all the directories in your path but prints duplicates.
'locate' is great but isn't installed everywhere (and it's often too verbose).
use the locate command to find files on the system and verify they exist (-e) then display each one in full details.
Greps located files for an expression.
Example greps all LaTeX files for 'foo':
locate *.tex | xargs grep foo
To avoid searching thousands of files with grep it could be usefull to test first how much files are returned by locate:
locate -c *.tex
