I have a folder which includes bunch of folders each having data files in them. [ Folder A has F1, F2 F3 ..... F1000 folders in it, and F1, F2, F3 ... each has about 10 different files named FILE 1, FILE2, FILE3 .... in them.
I am interested in File 1 of each Folder, because that contains the data I need in it. More specifically, that File1 s have a line "ANSWER=..." in them, and i need to get that value of the ANSWER from each file. So doing it by hand is so hard, so I need to write a script that will scan all folders and give me a list of values of eache ANSWERs.
I have two files of data with different numbers of columns and rows. I want to read this two files in two arrays and then compare for example the second column of first data file with the third column of the other text file and if the difference between of two numbers is less than a threshold then the program print the information in the rows which fulfill this condition in the third text file. I have written below program but the problem is that it does not go through all rows of second file.
declare -a a declare -a b r=` awk '{n++} END {print n}' second.txt ` echo $r awk ' {
[Code]....
Actually I have two data files one of them contains 44406 and the other one has 12066 rows and I want to check whether the difference between the components of two specific columns is less than a threshod but I have simplified it here. I had written this code and then I have realized that this code just goes through the number of rows as the same as the first.txt file and ignores the rest. I could not find the problem yet.
I'm having trouble reading EXIF data from TIFF files. Both 8 bit and 16 bit fail to load EXIF data via eye of gnome and GIMP and I'm not sure why. Neither files downloaded online nor rendered from Bibble 5 seem to work. Using Ubuntu 10.04 64bit and GIMP 2.7.2.
I have been saving an XML file wherein I shall be reading data, if and only if the XML is present on Hard Drive. If same is not present, the code shall generate first and next time it shall simply read and not jump into writing part again and again. The issue that I am facing is, I am deleting the file manually going to that location, and checking whether it is reading the data, upon investigation, I found that it is really reading the data although the file is deleted.
I suspected that there may be some cache issue from where it is picking values, hence it fired the command "sync; echo 3 > /proc/sys/vm/drop_caches" But it is still doing the same pattern.
I have got a problem while reading from the serial port. I'm working on iMX-31 board and Eclipse IDE. Whenever I'm trying to read any data through the serial port, it's displaying I/O Possible and the application is being terminated. After reading I'm trying to write this data on a file. Here are the excerpts from the code:

Code: c read sac file PROGRAM RSAC PARAMETER (MAX=1000) DIMENSION YARRAY(MAX) CHARACTER*10 KNAME
If we have a .so library elf in linux, will it be possible to find out the APIs supported by it. Or in other words, the functions that can be used along with the argument types and return type.? Note that we dont have any other header files or documentations related to the library.
I am currently writing an engine using SDL and openGL, and while I've gotten it mostly done, I've never really learned how to read configuration files. The configuration files that I'm hoping on using will be a straight forward syntax using "#" for comments and variables will be declared using "foo=hello". I don't need a lot of items in the configuration files, but enough to change needed settings. I'm not wanting to use external libraries (how are you going to learn if you can't do it yourself? :P) and I'm hoping to write it from scratch. If someone could please point me to a tutorial on how to do this or even some working code I may be able to figure it out. I am using the C programming language also(as I like it more than C++, sorry).
I am trying to write a simple script to list all the files in a directory. The script I wrote was as below where the pdb_files is a directory and all the files which I want to list are in that folder.
Code: files=`ls -F pdb_files/*THERMO*` for inFiles in $files do echo $inFiles
I have an application where I am sending data via serial port from PC1 (Java App) and reading that data in PC2 (C++ App). The problem that I am facing is that my PC2 (C++ App) is not able to read complete data sent by PC1 i.e. from my PC1 I am sending 190 bytes but PC2 is able to read close to 140 bytes though I am trying to read in a loop.Below is code snippet of my C++ AppOpen the connection to serial port
I have a file which contains the data i retrieved through prstat and an array that contains all the unique process ID's of that particular file. i want to compare each and every line in the file with each and every element of the array so that i can create multiple files for the multiple value in the array.
I use a mencoder line to convert .avi to .mpg (dvd player compatible), it works well but i can only do one file at the time. It requires giving the input and output directories and the files name. I tried using (*.avi *.mpg in the command) on the directory but it just add up all the .avi and convert them into one huge .mpg. My goal is to have a script that would convert all the .avi files from a directory to the same amount of .mpg and also keep the naming of those files. Here is what i work with on single files:
I feel kind of embarrassed posting here, but this is technically a scripting sub-forum. Here is the problem. I have a folder with various files which include .txt files as well
How can i redirect same content to each of the .txt files in the folder?
I have tried Code: $ echo "hello" > *.txt -bash: !": event not found Code: also cat ~/otherdir/test.txt > *.txt -bash: *.txt: ambiguous redirect Can anyone help me with this?Ok i solved it Code: #! /bin/bash for file in *.txt do echo "Text that needs to be written" > $file done
I use grep <pattern> abc.* to read the files. But here grep read files in the order of 1,2,3,4 . I want to to grep the files in reverse order like 1st the abc.4 file will be read and abc.1 file will be last.
how i could compile for example: a tutorial file of cantera open source files. when i do :g++ example.cpp -o examplei get huge errors such as the header files are not here,...please tell me how i could compile it. ofcourse i have configured the full opensources and i see in /usr/local/cantera/binthat the files are there but i still can not compile and execute any cpp file.
My query is i have a.sql , b.sql , c.sql files which needs to be executed using "$ db2 -tvf a.sql"; "$ db2 -tvf b.sql"; "$db2 -tvf c.sql" , script with which i can execute all these sql files in a single shot.
I am looking for the quickest way to do multiple searches for different files.Here is the scenario: I want to search for various icons one by one in a script. Preference is for the gnome icon theme.
The echo piped into grep part seems to take a long time. Is there a quicker way of doing this?I do not want to use slocate, sqlite or the like since that will require admin privileges to update the database and/or extra dependencies.
I have written FORTRAN code to calculate density profile. This code will open two files ( topology and x,y,z trajectory). The trajectory file contains XYZ data coordinates for multiple frames (about 20 or 100 frames for instance). One frame contains 20736 data.
Previously this code was written to open ONLY one input XYZ data file and do the calculation and would dump the results in separate file and it was running without problem. Recently my data file get bigger in size, so I decided to break the single XYZ data file into few small parts.
Now I have modified the code so that it calls the parts of the XYZ data files ( eg: maltoTHERMO_10Frames.traj, maltoTHERMO_20Frames.traj,... and so on) and do the calculation and dump the results in the same result output file. I have tested this code just with openning the XYZ coordinates and printing into another file to see wheather it collecting the data sequently and it was working fine.
This code supposedly read the x coordinate data and calculate distance and put a count accoding the criteria in the approperiate bins. But when I let the code to do the calculation it stop and shows error. (I have indicated as !** in the code). If I enable this line, it shows error but if I disable this line, than the code do collect only the XYZ coordinates.
compiling and linking using gcc: What does a file name with a suffix '.a' represent? If I have multiple .c and .h files, how can I link them together? How can I create the .a file?
I am working with DM355 target board. Here we record. The video coming from IP cameras. Now I have to write c program for copying. The recorded avi files with date and time to NAS server using scp. I wrote a script to copy single file to NAS server.
I want to change some HTML in my files (80+ so I prefer not to do this by hand). I got a script to replace a string in files, however the HTML I want to replace contains an enter (and tab of 4 spaces) (explanation below) Does someone know how I could update my HTML by using a function in Linux?
I also found sed but don't know how to use it with the enter (linenumbers will not work because they variate)...
I'm trying to change a group of cpp files to one shared lib. I have created a shared lib with a single file. I then did this with a group of files. The difference in what I'm doing is that before with the single file, .a, was added into a single .o file. Now I'm trying to add it to my main.cpp file which is NOT a .o file. I'm now getting these compiler errors from the main.cpp where is doesn't seem to recognize the semaphores.Example Error: undefined reference to `sem_wait'If I were not to use the share libs this compiles and runs as I expected it to.Something tells me this is a compiler flag issue, at least I hope it is
I have a problem - I have files with rows of data and I need to check if the next row (of the same type) has the NEXT date in it so I need to extract a date in YYYYMMDD format from a row (easy enough) then add one day to it and compare it to the the next date I encounter on a subsequent row.
I've been hitting my head against a wall for awhile with this one:As the last part of some data analysis I performing I would to construct a matrix from a series of different files. These files have the format:
I have wrote a 1 line command that parses a file, locates the IP Address in the file and then trims the output the way I want it, and then sorts numerically and by uniqueness and then >> appends to output.txt
I can get all the IP's into 1 file "output.txt", but what I am really looking for is some type of way to create a text file, for each IP it finds labeled xxx.xxx.xxx.xxx.txt and also put that ip address into that file..
I've been trying to sort this out for several hours and I?m totally lost? I?ve been searching around, but haven?t found the solution to my problem. I have a directory with 100 files. I need to copy 10 lines of each files (let?s say from line 45 to 55) into one unique file. So I guess I could use sed ?w, but I didn?t manage to write the right script. I also tried using a loop to create 100 different files, each one with the 10 lines) to concatenate them later on. But I only got 1 file, not 100.
