Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

Works in Ubuntu, I hope it will work on all Linux machines. For Unixes, tail should be capable of handling more than one file with '-f' option.

This command line simply take log files which are text files, and not ending with a number, and it will continuously monitor those files.

Putting one alias in .profile will be more useful.

Ever compress a file for the web by replacing all newline characters with nothing so it makes one nice big blob?

It is a great idea, however what about when you want to edit that file? ...Serious pain in the butt.

I ran into this today in that my only copy of a CSS file was "compressed" with no newlines.

I whipped this up and it converted back into nice human readable CSS :-)

It could be nicer, but it does the job.

User: LrdShaper
Functions: date

With this command you can get a previous or future date or time. Where can you use this? How about finding all files modified or created in the last 5 mins?

touch -t `echo $(date -d "5 minute ago" "+%G%m%d%H%M.%S")` me && find . -type f -newer me

List all directories created since last week?

touch -t `echo $(date -d "1 week ago" "+%G%m%d%H%M.%S")` me && find . -type d -cnewer me

I'm sure you can think of more ways to use it. Requires coreutils package.

This will allow you to mount a CD-ROM on Solaris SPARC 9 or lower. This will not work on Solaris 10 due to void and the volume management daemons.

This will issue a shutdown command to the Windows machine. username must be an administrator on the Windows machine. Requires samba-common package installed. Other relevant commands are:

net rpc shutdown -r : reboot the Windows machine

net rpc abortshutdown : abort shutdown of the Windows machine

Functions: cat less ls

To sort hidden files first, simply switch the two inner `ls` commands.

I have this aliased to `dira`

`dir` is aliased to the simpler version with no hidden files:

ls -l --color=always | less -R

Really only valuable in a PHP-only project directory. This is using standard linux versions of the tools. On most older BSD variants of sed, use -E instead of -r. Or use: sed 's/\+[[:space:]]\{1,\}//' instead.

The -d flag sets the lifetime of a metric and defaults to 0 hence why old metrics continue to be graphed in the dashboard. Submitting a dummy value and short lifetime ensures that the metric is removed from the dashboard.
