Bash: Get yesterday’s date
Filed Under Command line, Howto, Linux, Unix | 2 Comments
Recently I had to create a bash script to copy some files based on date.
The rule was copy yesterday’s files to …
But How to determine what was the yesterdays date?
The answer was in date man page.
Here are the parts from the script related to yesterday date:
$date -d '1 day ago' +'%Y/%m/%d' 2011/06/02
on Internet I’ve found also:
date --date='yesterday' Thu Jun 2 14:01:28 EDT 2011
And (Bonus!!) if you want to go in future 😉
date --date='tomorrow' Sat Jun 4 14:04:29 EDT 2011
Happy scripting…

Debian – upgrade to Squeeze
Filed Under Howto, Linux | Leave a Comment
After release of Debian 6.0 (squeeze) the question of how to upgrade from previous version to the latest.
It appears to be fairly simple process:
1. Edit sources.list
vi /etc/apt/sources.list
2. Replace distribution name (I appeared to have Lenny) with Squeeze.
%s/lenny/squeeze/g
Note: DebianVolatile has been superseded by squeeze-updates since Debian Squeeze.
To use squeeze-updates just add
deb http://mirrors.kernel.org/debian squeeze-updates main contrib
to sources.list
Then as usual:
apt-get update
apt-get dist-upgrade

tsclient toggle full screen mode
Filed Under Howto, Linux | Leave a Comment
When working from Linux to a windows machine via remote desktop the obvious choice is tsclient.
In windows you just move your cursor at the top of the screen to the control bar and there you can click the button for windowed mode.
But tsclient does not have that instead you can use following keyboard combination: “Ctrl-Alt-Enter”.
Tip: To improve tsclient performance just go to performance tab and check enable bitmap caching.

How to replace Windows Task manager
Filed Under Windows | Leave a Comment
In Windows world Task Manager is included in OS. It is easy to use for basic troubleshooting and to kill hanged processes.
But even the tool is powerful enough for everyday usage for further investigation or advanced use his abilities are simply not up to date.
Microsoft acquired Sysinternals a years ago and continued to develop and improve their tools. Furthermore they are freely available.
Process Explorer has much more:
- Updates a lot of system data every second
- It shows process trees and is useful of tracking DLLs
- You can investigate each process – his threads, interrupts, devices, registry keys etc.
- It is free and does not require installation
- in addition it could be easily configure to replace TaskManager.
If you are reading up to here you should be interested in the tool. Here is how to get it.
Go and download the latest version from Sysinternals website.
Unzip the downloaded file. c:\Program Files\ProcessExplorer is a good place.
Run procexp.exe and start to explore…
If you like the tool so much that you are ready to get rid of TaskManager in favor of Process Explorer simply go to Options menu and check Replace Task Manager as shown here:

Excellent tool for this job is dig – it allows you to see all DNS records like: A, MX, TXT…
Unfortunately the tool was not installed.
The proper way of installing it is:
apt-get update && apt-get install dnsutils
In case you did update recently you can skip the first command.

screen -r : Cannot open your terminal ‘/dev/pts/0’ – please check.
Filed Under Fix, Linux, Unix | 3 Comments
I love screen – it allows you to detach you console and still have the program running.
For more info:
man screen
Recently I experienced following error:
$ screen -r
Cannot open your terminal '/dev/pts/0' - please check.
After searching for solution I found several instructing to change permissions etc.
But different solution, almost “hack” is the one I like.
Before starting screen type:
script /dev/null
And after that you can type:
screen -r
Only drawback is that you need to type one additional exit for script to terminate.
Credits for this to Harry Jackson. Unfortunately the resource was not available so i did to put a link to the site.
