Using poppler-tools and psutils, you can extract a range of pages from a larger PDF file. For example, if you want to extract pages 11–14 of the PDF file afile.pdf, you could use the following command:
$ pdftops afile.pdf - | psselect -p11-14 | ps2pdf - file-p11-14.pdf
The pdftops command converts the PDF file to PostScript; the psselect command selects the relevant pages from the PostScript, and the ps2pdf command converts the selected PostScript into a new PDF file.
SOCKS is built in to OpenSSH, so it's a trivial matter to set up a local SOCKS proxy with the -D flag. For example:
$ ssh -D 12345 myuser@remote_ssh_server
will open up the port 12345 on your local machine as a SOCKS proxy so all your HTTP traffic can be specified to go through the SSH tunnel and out remote_ssh_server on the other end. Your proxy server is now set up.
Next, set up your browser to use the proxy server. Most browsers include proxy support. For Firefox 3, go to Edit→Preferences→Advanced→Network→Settings, and specify that you want to use a Manual Proxy, localhost, port 12345, and SOCKS v5 (although OpenSSH supports both versions 4 and 5).
Now your browser is using a secure tunnel to your remote SSH server.
Ever selected text from your terminal so you could paste it into an X application? Drop the mouse and use xclip instead. Using xclip, you simply can pipe the contents that you want to clip directly into xclip:
$ lspci | xclip
Then, go to your X application and paste the captured output into the application. xclip also lets you “paste” selected text into the terminal. Just use the -o switch to output the highlighted text from the active selection:
$ xclip -o
xclip can be found at sourceforge.net/projects/xclip.

Until recently, IBM’s Power Platform was looked upon as being the system that hosted IBM’s flavor of UNIX and proprietary operating system called IBM i. These servers often are found in medium-size businesses running ERP, CRM and financials for on-premise customers. By enabling the Power platform to run the Linux OS, IBM now has positioned Power to be the platform of choice for those already running Linux that are facing scalability issues, especially customers looking at analytics, big data or cloud computing.
￼Running Linux on IBM’s Power hardware offers some obvious benefits, including improved processing speed and memory bandwidth, inherent security, and simpler deployment and management. But if you look beyond the impressive architecture, you’ll also find an open ecosystem that has given rise to a strong, innovative community, as well as an inventory of system and network management applications that really help leverage the benefits offered by running Linux on Power.Get the Guide
