it should be simple, but i don`t get it: if i search for stuff, i may pipe it to grep to "filter" it:
Code:
ls /usr/bin | grep ice
but how would i say grep not to show the ones containing "term"/"string" example would be with locate
Code:
locate fluxbox | -> but not the ones in /home
I want to pipe the output of a command into grep as the search TERM, rather than the text to be searched, like this for example
Code:
cat /var/log/auth.log | grep date "&b &d"
so that I only see the lines in auth.log for the current day...but obviously that line doesn't work.... is there a way to do this with grep, or even another command?

Q: Is there any way to use grep and sed with a string variable rather than with a file?
The problem: Im running through a LARGE (about 10,000 lines) xhtml file and need to replace every instance of lines beginning <p>~
The following code works but takes a long time mainlly because an in/out operation needs to be carried out on each line. If I could read from a string rather than a file it would take a much shorter time!
Code:
#!/bin/bash
count=$((0))

echo "waiting....."

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".
How do I find a string in files in a directory. And these file names begin with letter a. I also want to get the number of occurrences of this string from the grep I run.

I am using grep to filter out directories I am not interested in like this:svn stat | grep -v data/charts | grep -v lib/model | grep -v web/picsIt seems a bit "hacky". Is there a better way to specify more than one string to ignore, so that I dont have to chain multiple grep commands?

I need to search a text file for a string of numbers which are different lengths, and always are between number=" and " like:
number="1234567890"
number="22390"
I need to grab those numbers and pipe each one to a line in a file. I've already tried something with awk and that didn't seem to work.
I forgot a lot of my command line. I am doing cat file | grep "error" and i would like it to show everything to the right of G:/ including G:/ if possible. I figure its an awk command but i dont know what. I tried awk '{print $8+}' but + does not work like i hoped and guessed.

What is the single command used to identify only the matching count of all lines within files under the /etc directory that contain the word „HOST? List only the files with matches and suppress any error messages.

Ive installed Ubuntu recently but none of my attempts to get the wifi network working were successfull. It establishes connection but the indicator shows no signal and I cant connect to any website, I tried pinging external IPs etc. None of these worked. lspci -nn | grep 'Wireless Brand'Does not show anything.

View 1 Replies View RelatedI'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.
