Is there any way to filter the output of a command based on the values on the output columns. For example i execute du -h on directory with many files. Now I want to filter the output based on the size (i.e. M or G or K ). The filtered o/p should contain only M(megabytes) or G(gigabytes) and also all columns.

How can I add columns to the right of GtkTreeView? How can I add the menu to the right of the window? How can I change the position of the icon in the GnomeMessageBox to the right of the dialog? And how can I change the arrange of the buttons from right to left in GnomeMessageBox? and position of the icon on the buttons in the GnomeMessageBox?
View 5 Replies View RelatedI have a file that contains a couple of email addresses and I want to extract the usernames ( Letters before @ symbol ). How can I do that using sed/awk.
I know cut will work, but the current environment doesn't allow me to use cut command. I can use either awk or sed.
Say I have a text file with10 columns. I need to reorder them based on a list of column numbers that will reorder them.
My problem is this:
If I want to cut out 5 columns (columns 1,2,3,9,10) in the order 1,10,2,9,3 then I have tried using:
Code: cut -f1,10,2,9,3 my_file.txt > reordered_file.txt But this just extracts the columns in order as if I used:
Code: cut -f1,2,3,9,10 my_file.txt > reordered_file.txt How can I cut these columns and place them into the new file in the order I specify?
While this might seem quite trivial, I will actually need to do this for a file containing ~14000 columns with ~12000 columns that I need to extract in a particular order.
Actually build a script which can monitor the "DateTimeHourMinute" in a data file.
I wanted to compare the "DateTimeHourMinute" from the 2nd column against "DateTimeHourMinute" on the 3rd column which located in the same line.
Below is the data sample:
I have a folder with only 24 files named <number>.dat (i.e. 4.dat, 6.dat and so on) where <number> is between 0 and 256. Each file has just two columns of data and nothing else.
I'm trying to combine all the second columns ($2) together. I've been fiddling around with getline and so far have
awk '{ getline ln < "6.dat" ; print ln" "$2 }' 4.dat
which takes file 4.dat and adds $2 from 6.dat, but I want a single command to take each $2 from every file and add them to (for example) 4.dat (having $1 from 4.dat is no problem). A command that takes every file in the folder and grabs $2 and places them in a common file would be ideal. Frankly I can work around if you combine both columns from every file.
I bet this is a Perl one-liner (or very simple python script).I have a tab separated files in which each row looks like:Unique_Eight_Character_Sequence [3 tabs] data1~moredata1~moredata1 [3 tabs] data2~ moredata2~ moredata2 ... dataN~.The output file should have each column converted into a row (with the unique character sequence copied in for the first column), and then each "~" replaced by a comma.

If I have a Query that returns columns where some of the values are NULL, is it possible to tell SQL to return all the NULL values as empty strings instead of the NULL datatype?

Might return:

I'm writing a script and I have doubts on how to assign values to an already established variable. The value for the vatriable would be coming from a file with three columns.

The script worked fine for my small testing files, but failed in my input file. The input file is 18MB and containing more than 300,000 lines. The output will contains some lines like that:
url_one 10 1
url_two 10 1
url_three 10 3
url_four 10 1
Is that because my file is too big for perl to handle ?
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?
I'm looking for a version of Getopts for Java that isn't licensed under the GPL and accepts long options (i.e. both -h and --help). My code is licensed under BSD and I don't really want to change that just because a module uses the GPL...
View 1 Replies View RelatedI have a folder named Pictures that contains a bunch of .jpg files. My problem is that they all have randomly numbered names, then there is a duplicate of the file that is random numbers then the letter a right before the .jpg.for example, there would be 123.jpg and 123a.jpg, where 123a.jpg is just a resized version of 123. What i'd like to do but have NO clue how to, is to have a script or something go through my Pictures folder, then copy the ones that end in a.jpg to a folder called Resized, and ones that dont have that to a folder called Originals. That way my Pictures folder will be in tact, and i'll have copies of them all separated out.I have to do this all through the CLI on a machine, maybe I dont even need a script and can just do it with a slick command?

View 2 Replies View RelatedI have a LAMP based web hosting account (BlueHost). I have an existing simple MS Excel application which I would like to make it web based. However I am not sure what tools or features of PHP are out there that will aid me with this task. Here are some details:
1. I don't want to create an entire Excel program online. For that there are plenty of existing applications like Google Docs, MS's own online version of Excel, etc.
2. My current excel file uses some of the following excel functions:
a) SUM
b) Product Sum
c) Conditional Formatting (like changing font color if an amount is below a threshold, etc.)
d) Sorting (Date, Amount)
e) Drop Down Box to select pre-defined values
3. Ability to add/delete/modify a entry (row)
4. I don't care whether the application has the same look-n-feel as MS Excel.
As you can see it is a very simple home grown excel application with few basic mathematical functions. Here are some few thoughts that I have currently in my mind:
i) Just start coding intuitively as you would develop a normal web based application.
ii) Do (i) but use some of the PHP's excel oriented helper functions (COMs?) if there are any
iii) Use completely a different set of tools permitting that they run on LAMP environment.
I could have started with (i) but before making a costly mistake I thought I would get some opinion from the community to see if this is the right approach.
I need to launch programs in my program and the program can be a script, a Linux executable or even a Windows executable. The first thing i tried is to use xdg-open from my program, but i can't pass arguments to it, otherwise it would have worked perfectly. Is there maybe a way to determine which program is set as default according to the mime-type of the program i want to launch? I also tried kfmclient and gnome-open, they don't allow arguments either.
View 2 Replies View RelatedOn an Ubuntu Server I am running, I wrote a small Ncurses program in GCC. It worked just fine.
Then, I copied the executable over to my Ubuntu 10.10 desktop edition with sftp. No matter what I did, it kept giving the error:

I had copied other non-curses programs and they all ran just fine.
Finally, I copied over the source, recompiled with GCC and voila, the executable now runs fine.

Since I'm not building a specific piece of software but a shell script, I hope this is in the right forum. At work, we use RHEL for the basic system but have Windows clients attached as well. On the Win side, there's a program that I'm trying to duplicate on the Linux side. Because of established procedures, I can't change the way files are named so please don't suggest I do that (my boss would not be happy). We have files stored on an NFS share we manipulate on either side.
The program is used to copy files from one directory to another, based on the filenames. The first two characters of the filename are ignored (they're for human-readable sorting purposes only), the next four characters are the time, and then all characters after that are ignored. The time is read and the file gets copied at that time. (This was all done in VC++ many years ago, and nobody knows where the source code is.) For example, a file named 2d0730abcd.txt would be copied from the source directory to the destination directory at 7:30am.
It seems to me that it should be fairly straightforward to build a shell script on the Linux side to do the same thing, but darned if I can figure out which magical combination of commands to use. Would the shell script end up creating a giant pile of AT commands?

What I am attempting to do is rename some television shows into the format that my PVR will understand for the naming convention. I have a script that cleans them up about 95%, now I just cant figure out the last little detail..
For example: NCIS_01.mkv
I think it can be done in sed, but I just figure out how. I need it to be renamed to: NCIS_s01e01.mkv
How can I make sed (or something else) match the last "_" and any numbers after it until the period and then insert text between them reliably?
Depending on the show, it can be something like: This_show_name_243.avi so I need it to be more flexible than I can figure out how to do..
I have a directory with some data files in it. I did an md5sum find, and built an index of all the files contained:
Code:
find ./* -type f -print0 | xargs --null md5sum > MD5SUM
Now, based on my new index, I want to find the copies of these files as they appear in a new directory, where they have been renamed and reorganized.
