Instant or Passwordless SSH-ing in Linux

March 3rd, 2008

Well, to be “correct” the title of this should have been “how to add your key to the list of authorized public keys on a remote or local linux machine”, but being a newbie like myself, I would not have known to search for it. If I wanted to find out about logging in automatically to a remote machine using a generated public key, I myself would have used “Passwordless SSH” – so there you go.

To get started, I’ll assume that you have OpenSSH set up (it’s setup by default… well usually) and that your remote machine has OpenSSH-server set up.

If not, then do the following on the remote machine:

$ sudo aptitude install openssh-server

Adding Multiple files to SVN repository

February 18th, 2008

I was surprised that there was no built in way of adding multiple files to a SVN repository. I did a quick search and it seems that there is “one easy way” – execute the following piped command line from a Terminal window.

you@yourmachine$ svn st | grep "^?" | awk '{ print $2}' | while read f; do svn add $f; done

I could have sworn that I came across an easier way of doing this without resorting to doing the above.

YeahConsole a lighter yakuake alternative for xubuntu linux

January 17th, 2008

This week, I’d like to talk about YeahConsole, an alternative to yakuake, or a more “native yakuake” for xubuntu and ubuntu. You could also look at it as a lighter terminal emulator wrapper for those who do not really like installing extra kde packages just to use yakuake.

Execute Linux commands in PHP by using backticks

January 13th, 2008

You can execute linux commands within a php script – all you have to do is put the command line in backticks (`).

Recently, I had to upload an archive to a server which did not allow ssh. For files that I need to transfer, I just package them up in a neat archive and transfer the archive file via scp. Not having ssh access however, I uploaded the archive file via ftp and created a script which extracts the file the file looks like the following:

Quick Linux Shell Script Example

November 22nd, 2007

When I first moved to linux I had become addicted to keeping my distro updated and so I found myself typing and retyping

$ sudo aptitude update
password:
$ sudo aptitude dist-upgrade

At least once a day. Having read about shell scripts, I thought I’d try my hand at putting this into a shell script which, if you don’t already know, is linux’ more powerful answer to the Windows batch file.

So that’s what I did, and here’s how I did it.
