Check These Out

Redefine the cd command's behavior
Often, the very next command after the cd command is 'ls', so why not combine them?. Tested on a Red Hat derivative and Mac OS X Leopard Update: changed ${1:-$HOME} to "${@:-$HOME}" to accomodate directories with spaces in the names

Find the package that installed a command

Extract title from HTML files
This command can be used to extract the title defined in HTML pages

Make changes in .bashrc immediately available
Simply sourcing .bashrc does not function correctly when you edit it and change an alias for a function or the other way round with the *same name*. I therefor use this function. Prior to re-sourcing .bashrc it unsets all aliases and functions.

Give to anyone a command to immediatly find a particular part of a man.
Example : $ LC_ALL=C man less | less +/ppattern

Convert string to uppercase

Create a mirror of a local folder, on a remote server
Create a exact mirror of the local folder "/root/files", on remote server 'remote_server' using SSH command (listening on port 22) (all files & folders on destination server/folder will be deleted)

Append a pub key from pem file and save in remote server accessing with another key
Useful if you need to add another key and you using pem files (typical in AWS EC2 Instances). If you use it in EC2 instances, remember that password authentication is disabled, so you have to use the first key generated when you generated the instance

Find the modified time (mtime) for a file

Which processes are listening on a specific port (e.g. port 80)
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"
