Logtool is a nice tool that can export log file to various format, but its strength lies in the capacity of colorize logs. This command take a log as input and colorize it, then export it to an html file for a more confortable view. Logtool is part of logtool package.Tested on Debian.

: new command allow to split a Vim screen in two separate windows. Each window can handle its own buffer.

Passing the -c new options when Vim start cause to split screen automatically.

Nload is part of nload package, tested under Debian. Nload display network bandwidth statistics, -u m options stands for MBit unit measure.

you don't need to echo, just a plain redirect is enough to empty the file

Empties all files in /var/log over 5000k. Useful if /var goes crazy or if you just haven't cleaned up in a while.

sudo ipfw pipe 1 config bw 50KByte/s

Set the bandwidth (bw) limit to any number you want. For example you could have a 15kb pipe for X application and then a 100kb pipe for another application and attach things to those pipes. If a port isn’t attached to a pipe, it runs at full speed. Change the number (in this case 1) to a different number for a different pipe.

The next step is to attach your port.

sudo ipfw add 1 pipe 1 src-port 80

In this case anything on port 80 (http) will be set to a limit of 50Kbyte/s. If you want to attach a second port to this pipe, repeat the command but change the port number at the end.

This will compress the root directory to an external hard drive and split it to parts once it reaches the 4 Gigs file system limit.

You can simply restore it with:

Found this one little more for me. This one removes the perl dependency (from command 2535).

Source for command : http://www.earthinfo.org/linux-disk-usage-sorted-by-size-and-human-readable/

this bzips a folder and transfers it over the network to "host" at 777k bit/s.

cstream can do a lot more, have a look http://www.cons.org/cracauer/cstream.html#usage

for example:

hehe :)

Solves "tr" issues with non C-locales under BSD-like systems (like OS X)

just a alternative using a saved html file of all of my bookmarks. works well although it takes awhile.

using mb it's still readable;) a symbol variation

$ du -ms {,.[^.]}* | sort -nk1

kpartx can be found inside of the multipath-tools package

-a adds the mappings and -d deletes them

I prefer to use this and not the -n variety, so I get DNS-resolved hostnames. Nice when I'm trying to figure out who's got that port open.

It bypasses encryption overhead of SSH and depending on configuration can be significantly faster.

It's recommended to use only in trusted networks.

A short, *easy-er* to remember command for stripping whitespace and comments from a config file, (or any file for that matter).

Remember regex as:

slash, space, star.

pound, slash, bar.

pointy-hat, dollar. (or "caret, dollar" if you must)

:-P

When you don't have c_rehash handy. Really simple - if you have a .pem file that doesn't really contain a x509 cert (let's say, newreq.pem), it will create a link, simply called '.0', pointing to that file.

avoid rm to be recursive until you complete the command: put the -rf at the end!

When a fs hangs and you've just one console, even # ls could be a dangerous command. Simply put a trailing "&" and play safe

If your last command was a dud, your bash prompt will be angry at you. Otherwise it's happy. Soon you will crave its constant approval and your linux skills will improve simply to avoid low self-esteem.
