Programming :: Split A String By Every Nth Characters?
Jan 17, 2011
splitting a string by every nth characters. I'm using Python 2.7.1 because I'm using older libraries, if that matters.
For example, if this is my input:
Quote:
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed ac elit nibh, vitae venenatis ligula. Vestibulum a varius turpis.
Splitting it by every 10th character should produce this list:
Quote:
[ "Lorem ipsu", "m dolor si", "t amet, co", "nsectetur ", "adipiscing", " elit. Sed", " ac elit n", "ibh, vitae", " venenatis", " ligula. V", "estibulum ", "a varius t", "urpis." ]

My problem is to insert one sign like space or ':' into a line or string.The goal is to get a demiliter for `cut`.I tried to do it with `tr A-Z "'A '-'Z '" and such but without success.I guess a while read loop could do it but I don't know howto use it with ` expr length $STR`

I am working with a Tcl script and have some strings in the following format (RE):
[a-zA-Z]+[0-9]{6}-[0-9]
There are some leading letters, combinations of capital and lowercase. Then six digits, followed by a hyphen, then one more digit. I would like to remove all of the leading alphabetic characters from the string. The resulting string would then be in this format: [0-9]{6}-[0-9]. In other words, six numeric digits, a hyphen, then one more digit.
I have tried:
Code:
set newstr [string trimleft $origstr alpha]
But that only removes the first alphabetic character, not all of them.
I couldn't get anything with regsub to work correctly, but I am somewhat of a noob with RE's in general and regsub in particular. There are usually 5 leading letters at the beginning of these strings, and I could in most cases get away with using string replace and constant indices to extract the substring. However, my preference is for this to be robust enough to handle all cases with 1 through n leading alphabetic characters.

I have a file with a number of strings like the ones below
string1#m1asdfe23easdf23wefas
string2#mfaaeb2vr1rhserh
anotherstring#ji89ensrsegr
anotherone#m1ynmdt324nsdt
I'm trying to delete everything after #** so that
string1#maasdfeaveasdfawefas
string2#mfaaebvrserhserh
becomes
string1#ma
string2#mf
tried sed 's/#..*//g' but as you all will know it returns string1, string2 etc.

What I am doing is reading the text from a text document and storing all of the text inside of a ArrayList. I then set one of the values of the Arraylist as a string. I want to use regular expressions find out what the first two characters of the String are. if first two characters = "//" then function(); I only care about the first two characters though. If you need any more information, just ask.

I'm trying to split a string, to later iterate using a for loop like
Code:
for (( i=0; i<5; i++))
But, my script returns an array with the size 1.
Here's the script:
Code:
aver=$(grep "avg" A.txt | awk '{ print $2 }');
a=$(echo $aver | tr " " "
");

this seems like it should be a simple thing, but I can't find it. Is there a bash shell command that allows you to create a string of repeated characters? Like a string of 100 '*'?

I am having difficulty getting sed to replace a string of text in an XML file, despite the fact that I have no trouble using grep to find that same string. Since the new string and old string to be replaced contain a lot of special characters, I thought it best to store them in variables as opposed to using a slew of backslashes:
OLD_STRING='<property name="webServiceHost">${jboss.bind.address}</property>'
NEW_STRING='<!--<property name="webServiceHost">${jboss.bind.address}</property>-->'

Below is extract of my file:
What I need is to replace "--destination-path=" with "--destination-path=/home/dest"
i.e. desired output is ----destination-path=/home/dest
I could achieve it with below command
$cat outgoing-xfer|grep destination-path|perl -pi -e "s/destination-path=/destination-path=/home/dest/g"
But the problem is that in this case i just wanted to append "/home/dest" for which I could easily escape "/" with just two "", but I wonder if i have a long path like "/a/b/c/d/e/f/g/h/i/j" I will have to escape so many /. Is there any other way by which I can avoid escaping forward slash.
I tried following:
But receiving follo error
Bareword found where operator expected at -e line 1, near "s/destination-path=/'destination-path=/home"
syntax error at -e line 1, near "s/destination-path=/'destination-path=/home"
Bad name after dest' at -e line 1. tried with enclosing in double quotes as well but in vain

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.
[Code]....
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.

So if I'm given a location of a file like:
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.

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.

How do I catch the output of split and redirect it to another directory?for example,if my working directory is 'Documents' and I split a file called text.one into 4 files of 100 lines each (xaa, xab, xac, xad), how would I get those split files to be written into 'Directory/subdirectory' instead of 'Directory'?And is it possible to rename those split files so that the split name is suffixed with the original file's name e.g instead of xaa, xab... can they be written as text.one.xaa, text.one.xab..?I've thought about using '>' to send the output to a new directory but it doesn't work; and I've thought about piping the results to another command but I don't know what that other command should be.

I'm currently teaching myself perl. I'm trying to write a program that unscrambles words by comparing each element in the array. There is an input file where you type the words to be unscrambled and there is a word list file containing approximately 1300 words. After everything has been processed the program is supposed to paste those words to an output file.
Code:
#!/usr/local/bin/perl
#use strict; #always add this in the beginning of code.
#use warnings; #always add this in the beginning of code.
#open(INFILE, '<', 'sample.txt'); # For reading
#open(INFILE, '>', 'sample.txt'); # For writing
#open(INFILE, '>>', 'sample.txt'); # To append .....
