I'm having problems completing my school exercises with awk.
Heres the desired outcome:
./my_awk 2 ACG GAG ATT AGG AGG ATC CCA CCA CAC AGG ACG GAG ATT AGG AGG ATC
So it generates data in group of threes, 8 groups per row and prints it. My problem is that I can't seem to get awk to append stuff to string so I could print it nicely to screen. It just prints empty lines per the parameter given to it.
I have the following function that does not iterate through the array I want to be able to do some manipulation on each element in the array[@].it appears the below array has only one item in the array whereas i want the array to have 3 items hence the loop three times printing the message Any ideas why this is not happening ?
I want to append a variable string to the end of a specific line. not like append the same string to each line. like in my file i have 4 columns, i want to add a string in 5th column in some fixed row.
I have my own declared types and I have to operate with lists of items. I wish to write a one macro, instead of using a function for each type. It's intended to be like this: Code: #define ____append_to_list(head,
From a file I want to extract a range of lines by patterns. I've used variations on
Code: sed -n -e '/^BashNotes/,/^EndOf[A-Za-z]*$/ p' -e '/^EndOf[A-Za-z]*$/ q' Notes
So, I want to extract lines starting from one whose first word is specified, in this case "BashNotes", and ending at the first line consisting of the single word "EndOf...", which in this case would be "EndOfBashNotes".
Either I get no output at all, or it prints from the start of file to the first EndOf..., so the problem has to be with "^BashNotes", e.g. remove the "^" and it accesses an earlier occurrence of "BashNotes" that is in the middle of the first line of the file, and prints to the first occurrence of "EndOf...".
So why should a "^" in the "from" pattern be objectionable, when it is acceptable in the "to" pattern and the "quit" statement?
I am trying to get this script to work. The purpose is to download a list of modules from the slax.org the list consist of a list of module numbers. What I am trying to do is Download the file or the file name corresponding to the number in the list.the list is comma delimited. this is what I have done so far and I am a stand still.
#!/bin/sh # Wget script to retrieve modules from slax.org modules # # ----Begin of user defined values ----- # Path to wget
I've been trying to understand pthread in C a little better. So I made a simple program that takes in a string from the command line and creates a thread to print the string. I've looked online and copied the basic concepts but there are something things I'm confused about. The programs works just fine, but I have questions. Here's what I have so far.
One thing I'd like to know is why the 3rd argument in the pthread_create function which is my SendMessage function needs to be typecasted to a void pointer and then send the address of the function. Also as for the 4th argument, I would see typecasting to void pointer in some of the pthread examples I saw online, but in my case I'm passing a char pointer, would this be correct? In which case would I ever want to pass a void pointer?
Do I need a pthread_exit(NULL) in my main and in the SendMessage function? If so, why? I added the sleep() function so that I could let the pthread_exit function in my SendMessage function execute first. I simply saw that the online examples on pthread had pthread_exit() in both locations.
I am an uploader to a various hosts, so this tiny script me a lot. I make a rar archive and split files with 100mb. I could get 3-4 or even 76 parts of rar files and it would take me some time to paste all these urls to remote upload function of filehosting sites. For example:
server:/home/cober/downloads/teevee# ls -al total 358784 drwxrwxrwx 2 root root 4096 Dec 8 19:38 .
I need to creates string suffixes out of a Reference string. for eg. suffixes of abcdefg will be
1)bcdefg 2)cdefg 3)defg and so on...
create an array of pointers to point to the first few characters and then use that pointer to print the rest of the string.But when i print using the pointer i get GARBAGE values! shudn't std::cout<<ptr[w] print the string following the char it is pointing to? why do i get garbage values?
How can I just take the type of the file at the end? I know I can use strrchr() for a period to get the pointer to the period just before file type. Is there a build in string function that will just take the rest of the string from a certain point on forward in the string? I know it wouldn't be much work to make it myself, but I figured I would find out if it already existed before doing it.
Is there a way, preferably in python or BASH, to rename files from a list? for instance, track1.mp3, track2.mp3 should be renamed to the names stored in a file listing song names. I have tried to loop a variable through directory listing and renamed them, only to find that filenames with spaces can't be assigned to a variable as a whole. To solve the problem above, I have tried the read command in BASH, which enables the program reading line by line from a list. However, It was failed to pipe the results from directory listing to the read command.
I need to, through a bash script, go through a given directory (given as argument 1) to list out the relative path in this directory (including $1) for eact subdirectory which contains files. Directories which only contain . .. and eventually only subdirectories SHALL NOT be listed. It is this last requirement that makes it difficult for me.
I have been using the tree command for now, but I have not found a way to ignore paths to directories which only contains other subdirs or nothing at all in any easy way. I may offcourse test each directory after they are listed but this gives an extra loop to go through and I beleive it should be possible to do it directly when creatring the list. I guess by using find or ls in conjuntion with the tree command or by itself it should be possible but I am not to conversant of nested script commands.
I've been given a custom-made string class which handles string, wstring and bstr. It has a number of methods and assignment operators to convert to and from different types. The app I work on compiles happily in VS6 and VS2008, but when trying to compile in Redhat (version 4.1.1 in Redhat 5.0)
I have the following two type of strings1: A/D2: A/C/DI am trying to write a subroutine to check whether all of the letters in string 1 appears in string 2. If yes, return true. If not, return false. In the above example, all the letters (A and D) in string 1 are also present in string 2, so I return true.
The s means substitute The $ in this particular regex (regular expression) means end of the line. The ; is what you're subbing. This works fine and well, but what if you want to append a / at the end of the line?
