Directly attach a remote screen session (saves a useless parent bash process)

command to decrypt:

Of course, don't forget to rm the original files ;) You may also want to look at the openssl docs for more options.

This executes faster than

I put this in a script and added it to my path:

#!/bin/bash

if [ $# -eq 0 ]; then

explorer.exe $( cygpath `pwd` -w ) &

else

explorer.exe $( cygpath $1 -w ) &

fi;

Using the script you just type

Note: you can do this for any file that has an associated executable in the windows registry. This is quite handy if you want to open pictures or movies from xterm.

converts any number on the 'stdin' to SI notation. My version limits to 3 digits of precious (working with 10% resistors).

a shorter version

This command finds the 5 (-n5) most frequently updated logs in /var/log, and then does a multifile tail follow of those log files.

Alternately, you can do this to follow a specific list of log files:

sudo tail -n0 -f /var/log/{messages,secure,cron,cups/error_log}

Instead of calculating the offset and providing an offset option to mount, let lomount do the job for you by just providing the partition number you would like to loop mount.

Shows a single line per interface (device), with its IPv4 settings.

Shorter command, better readability in output.

a variation of avi4now's command - thanks by the way!

to clean up the extra lines

Same as above but slooooow it down

another way to output the IP address' of the system

That one works on Linux. On BSD and Solaris, the ifconfig output is much easier to parse:

making lots of configurations to apache and restarting the server only to find it broken just plain sucks.

Found this useful for scripts where I needed to work with the machine's IP. If $DEVICE is not specified, this will return all IPs on the machine. If $DEVICE is set to a network adapter, it will return just that adapter's IP.

This is *NOT* about the -i option in grep. I guess everybody already knows that option. This is about the basic rule of life that the simplest things are sometimes the best. ;-)

One day when I used "grep -i" for the umpteenth time, I decided to make this alias, and I've used it ever since, probably more often than plain grep. (In fact I also have aliases egrip and fgrip defined accordingly. I also have wrip="grep -wi" but I don't use this one that often.)

If you vote this down because it's too trivial and simplistic, that's no problem. I understand that. But still this is really one of my most favourite aliases.

This alias finds identical lines in a file (or pipe) and prints a sorted count of them (the name "sucs" descends from the first letters of the commands). The first example shows the number of logins of users; the one who logged in most often comes last. The second example extracts web client IP addresses from a log file, then pipes the result through the "sucs" alias to find out which clients are performing the most accesses. Or pipe the first column of ps(1) output through "sucs" to see how many processes your users are running.

Simply shows virtualhosts enabled, root access not needed (assuming apache2ctl is non-root executable).

Lists virtualhosts currently enabled for apache2, showing the ServerName:port, conf file and DocumentRoot

This command can be used with xclip or xsel for use on a linux box.
