Check These Out

print character classes
Today I needed a way to print various character classes to use as input for a program I was writing. Also a nice way to visualize character classes.

Removes file with a dash in the beginning of the name

Watch RX/TX rate of an interface in kb/s
Just a simple way without the need of additional tools. Of course, replace eth0 with your IF.

check open ports without netstat or lsof

Retrieve a list of all webpages on a site
This spiders the given site without downloading the HTML content. The resulting directory structure is then parsed to output a list of the URLs to url-list.txt. Note that this can take a long time to run and you make want to throttle the spidering so as to play nicely.

Bind a key with a command
the -x option is for binding to a shell command

Show top running processes by the number of open filehandles they have
I think I could cut down the number of pipes here, any suggestions?

view the system memory in clear text
see what's in your memory right now... sometimes you find passwords, account numbers and url's that were recently used. Anyone have a safe command to clear the memory without rebooting?

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)

View and review the system process tree.
The "pstree" command uses special line-drawing characters. However, when piped into the "less" pager, these are normally disabled.
