typing history it's a long way but typing only h it's my way it works in whatever distro or OSes or shells that you use, you know, only for easyness :)

Displays only the VGA adapter/chipset being used for the graphics. In this case, it gave me the "M22" and "Mobility Radeon x300" that I needed to research a graphics issue I was having.

This is useful if you have need to do port forwarding and your router doesn't assign static IPs, you can add it to a script in a cron job that checks if you IP as recently changed or with a trigger script.

This was tested on Mac OSX.

Use date to find the date at other days and times.

ls -S -lhr

This command list and sort files by size and in reverse order, the reverse order is very helpful when you have a very long list and wish to have the biggest files at the bottom so you don't have scrool up.

The file size info is in human readable output, so ex. 1K..234M...3G

Tested with Linux (Red Hat Enterprise Edition)

netstat -an | grep ESTABLISHED | awk '{print $5}' | awk -F: '{print $1}' | sort | uniq -c | awk '{ printf("%s\t%s\t",$2,$1) ; for (i = 0; i < $1; i++) {printf("*")}; print "" }'

Functions: awk grep netstat sort uniq

Written for linux, the real example is how to produce ascii text graphs based on a numeric value (anything where uniq -c is useful is a good candidate).

If you're a moron like me, sometimes your fingers get away from you and you, for example, enter your password when you're already authenticated to ssh-agent, sudo, etc., and your password ends up in shell history. Here's how to get it out.

url can be a working copy or url to a svn repository, revision is any valid revision number for that branch.

Certain codecs in high res don't play so well on my Dell Mini 9. Using this command, I can play just about anything and it keeps the sound in sync to boot!

Also works with files:

cat file

Hello world

base64 file

To decrypt use the -d option:

echo SGVsbG8gd29ybGQK | base64 -d

Hello world

A script that checks if your environment is correctly configured for using cobbler.

Add a repo to cobbler. To download all the repository contents the command is:

Lam is a command available on Bsd (I've tested it on OpenBSD).Is useful for laminate a file line by line. The -f option set the field width ( -f min.max ).

download a specific file with -f to not display errors and -O to write output to a file named as the remote file.

There was another line that was dependent on having un-named screen sessions. This just wouldn't do. This one works no matter what the name is. A possible improvement would be removing the perl dependence, but that doesn't effect me.

Not a discovery but a useful one nontheless.

In the above example date format is 'yyyymmdd'. For other possible formats see 'man date'.

This command can be also very convenient when aliased to some meaningful name:

alias mkdd='mkdir $(date +%Y%m%d)'
