Programming :: Grep A String With Space?

Feb 9, 2010

I am using Sun 5.9.

I am putting the value "Feb 10" in variable 'c' here.

Code:
-bash-3.00$ c=`date | awk '{print $2 " " $3}'`
-bash-3.00$ echo $c
Feb 10

But when I am grep-ing value of 'c', I am getting this error.

Code:
-bash-3.00$ ls -lrth | grep $c
grep: can't open 10

This is because there is a space between "Feb" and "10".

Programming :: Including A Space Taken From String In A Var?

Jul 26, 2011

I have a tsv file that I'm trying to break down, line by line, then column by column so to speak. The file is a list of exported usernames, passwords, and display names from an email server, I need each separate to be used in other commands to provision the new server. My problem is, each display name contains a space, as usual with people's names. Here is the script for reference:

pass=`echo $line | awk '{ print $2 }' >> works`

General :: Parse String In Bash Script?

Nov 8, 2009

I have to create a bash script that takes an arbitrary length number from the command line, and add up each individual digit

Ex:
server> myscript.sh 123
server> 1 + 2 + 3 = 6

The problem I'm having is pulling out each character.

Is there a way in bash I can parse the input string for each character? I can't figure out a way to do this.

Programming :: Pthread - Take String From The Command Line And Creates A Thread To Print The String

May 3, 2011

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.

Programming :: C - Put A Specific Arbitrary Part Of A String Into It's Own String?

Apr 18, 2010

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.

Programming :: Parse Text For Host List?

The important bits are hostname(ex compute-1-1) and number of cpus to use(ex 2). And for this program, it wants them in this form, a shell variable: HOSTLIST=hostname:cpus=X hostname:cpus=X .... I've tried this script, but it doesn't work

Programming :: Parse And Modify File Without Creating A Copy?

Nov 4, 2010

I don't think this is a "perl one-liner" of find and replace. I'm trying to auto-fill some information in a listing of files. The simplest example is that in the files the following exists:

I would want the script to find this and populate it with something like -- Date : 20101004-1758

I have a few more similar fields to autofill, and I'd like to do this from within a larger perl script I'm developing to process these files. So, how I perform in-place file modification from within a perl script?

Programming :: Bash - Parse Apache Log For Requests Per CIDR / 24

Feb 6, 2011

I'm trying to figure out how I can get a request count per CIDR/24 from an apache log in combined format - e.g.:
Code:
24.147.44.122 - frank [10/Oct/2011:13:55:36 -0700] "GET /apache_pb.gif HTTP/1.0" 200 2326 "[URL] "Mozilla/4.08 [en] (Win98; I ;Nav)"

I'm stuck using BASH for this and I generally write everything in Python, or even Perl if necessary so BASH isn't the most comfortable for me. I've got enough to extract the IPs and get a count I just need a slick way to come up with a sum on a per CIDR basis.

Programming :: How To Parse And Modify Keywords Using Shell Script?

Apr 14, 2011

There is a file with that format of each models' information.I don't think that's good format, but I cannot change that format. I needed to modify the model name, 'model = xxx' as 'model = abc'.And I don't know how to parse and modify 'model = iii' and 'model = ddd'.The only clue to parse 'model = ddd' is the second 'model = ' after the second 'system information'. But how to parse the second keyword?Is it possible with 'sed'?I sometimes have to modify the information of the file.using shell script if possible.Python is ok. (Shell script is better for me.)
