Programming :: Script To Delete Aligned Single-character Columns With No Field Separator?

Apr 20, 2010

The lines beginning with greater-than symbols are the sequence descriptors and the lines immediately after each descriptor with A-Z characters, dashes, and question marks are the aligned DNA sequences. The sequences are always the same length within a file and never span/wrap across more than one line.I am trying to write a script to remove positions in the sequences that are only represented by a -, X, ?, or N (these represent gaps or missing data). Also, if there is exactly one non-gap/missing character in a position it is also useless (there is nothing to compare it to) so I would like to remove those positions as well.

Position 5 (from the left) was removed because it was all gap/missing characters. Position 9 was removed because only one character was a non-gap/missing character. Position 10 was retained because there were 2 non-gap/missing characters.I'm really not sure where to start here. My first concern is I can't figure out how to tell awk to treat each character in lines not containing a greater-than symbol as a separate field. After that, I'm thinking I should use set up a counter to count the number of lines with gap/missing characters comparing that to the total number of lines not containing greater-than signs?

General :: Delete Files On The Command Line With Regular Expressions?

May 6, 2010

Lets say I have 20 files named FOOXX, where XX is the number of the file, eg 01, 02 etc. At the moment, if I want to delete all files lower than the number 10, this is easy and I just use a wildcard, eg rm FOO0* However, if I want to delete specific files ina range, eg 13-15, this becomes more difficult. rm FPP[13-15] does not work, and asks me if I wish to delete all files. Likewse rm FOO1[3-5] wishes to delete all files that begin with FOO1 So, what is the best way to delete ranges of files like this? I have tried with both bash and zsh, and I don't think they differ so much for such a basic task?

Ubuntu :: Frozen Panel - Messing Around With The Alternate Character Panel App And Made A Custom Character Set

Jun 12, 2011

I was messing around with the alternate character panel app and made a custom character set. I then wanted to put it on a new panel and created a new panel. I moved the character set to that panel, and then started to mess around with the panel settings (auto hide, show hide buttons, and expand, to be specific.) So far so good, until I moved the panel from the right side of the screen to the top. I already had a panel here, and it seemed not to like hiding a panel when there was already one on the top.

When the new panel hid itself, all my panels stopped responding (any clicks on them did nothing) and my processor started going at 100%. I tried a reboot and the only thing that changed is that now I can't even see my panels. I'm guessing I need to change the settings back manually through the prompt, but I don't know how to do that. I am using 10.04 and have not upgraded gnome since upgrading to 10.04.

Ubuntu :: Command To Delete Non-admin Software?

Feb 18, 2011

This is a bit of a longshot but I was wondering if anyone has a command to delete all the non-admin software from ubuntu. E.g. Openoffice, firefox, media players, photomanagers... Reason being is that there is an image of ubuntu which is specially optimized for my hardware but its on a standard ubuntu install, where infact all I want is file and printer sharing, chromium and xbmc (with any dependancies). I want the install to be as small as possible so I was wondering if anyone has done this before and knows a one line command for it? I would try building my own image from ubuntu sever but I think it would take too long.

General :: Bind / Map Character To Alt+?

Dec 23, 2009

In programming and various terminal programs (Screen, Vim) the [, ], { and } tends to be used a lot. I'm using a Norwegian keyboard where these are placed such that I have to stretch my fingers a bit too long for whats comfortable. To make it easier I though I'd try to make alt+[some key] be one of these characters. Is there a way that I can bind, say alt+� (Norwegian letter) to '{' system wide?Btw, is such thing called binding, mapping or something else? I'm getting a bit confused by the terms...

Jul 9, 2010

I am attempting to set a character set of IBM850 on slackware linux for a particular application (epic5). I am using rxvt-unicode and have setup LANG/LC_*=en_US. Now if I set the encoding to IBM850 in kde's konsole program im able to display certain characters correctly. I'd rather not use IBM850 for everything; is there a way to set/alias a command for a per application execution?

I've tried things like:
LC_CTYPE=IBM850 epic5
LC_ALL=IBM850 epic5
