this works on Solaris, so not better than the "only-GNU"-tool :-(

I think, there is no one-liner for this, that will work on all *nix-es

- convert unixtime to human-readable with awk

- useful to read logfiles with unix-timestamps, f.e. squid-log:

sudo tail -f /var/log/squid3/access.log | awk '{ print strftime("%c ", $1) $0; }

middlehost allows ssh access from where you are but not securehost.

Use nice ssh piping to simulate scp through A => B => C

setting up the shell function if left as an exercise for the reader. ;-)

Agent forwarding should avoid password typing.

Uses the data in the /proc system, provided by the acpid, to find out the CPU temperature. Can be run on systems without lm-sensors installed as well.

This command changes all filename and directories within a directory tree to unaccented ones. I had to do this to 'sanitize' some samba-exported trees. The reason it works might seem a little difficult to see at first - it first reverses-sort by pathname length, then it renames only the basename of the path. This way it'll always go in the right order to rename everything.

Some notes:

1. You'll have to have the 'unaccent' command. On Ubuntu, just aptitude install unaccent.

2. In this case, the encoding of the tree was UTF-8 - but you might be using another one, just adjust the command to your encoding.

3. The program might spit a few harmless errors saying the files are the same - not to fear.

Useful to move many files (thousands or millions files) over ssh. Faster than scp because this way you save a lot of tcp connection establishments (syn/ack packets).

If using a fast lan (I have just tested gigabyte ethernet) it is faster to not compress the data so the command would be:

tar -cf - /home/user/test | ssh [email protected] 'cd /tmp; tar xf -'

to download latest version of "util", maybe insert a sort if they wont be shown in right order.

curl lists all files on mirror, grep your util, tail -1 will gets the one lists on the bottom and get it with wget

I have a small embedded linux device that I wanted to use for sniffing my external network, but I didn't want to recompile/cross-compile snort for the embedded platform. So I used tcpdump over ssh to pass all the traffic as pcap data to a "normal" Linux system that then takes the pcap data and passes it to snort for processing.

Don't need to pipe the output into rs if you just tell jot to use a null separator character.

Type the command in the terminal and press enter to create the tweet() function. Then run as follows:

tweet MyTwitterAccount "My message goes here"

It will prompt you for password. Make sure that you use escape "\" character in message for showing varialbles or markup.

First look into /etc/modules if you have unionfs (or squashfs) support. If not, add the modules. UnionFS combines two filesystems. If there is a need to write a file, /tmp/unioncache will be used to write files (first create that directory). Reads will be done where the file is found first.

use the locate command to find files on the system and verify they exist (-e) then display each one in full details.
