I am trying to search for
Code:
<cats>
Sports
</cats>
how do i use the find command to search for <cats>Sports The problem here is that the word Sports is in the next line of <cats> so I cant use -
Code:
find /test/upload/ -type f -name "*.xml" -exec grep -l "<cats>Sports" {} ; -print
How do I put the next line string?
How do yo find a pattern with sed or awk and then:
- add a # at the beginning of the line containing it
- and add a # at the beginning of the following 2 lines, too?
Say, I want to comment out the line containing "which 0launch" and the two lines following it:
if [ -x "`which 0launch`" ]; then
exec 0launch http://rox.sourceforge.net/2005/interfaces/ROX-Filer -S
fi
Expected result:
#if [ -x "`which 0launch`" ]; then
# exec 0launch http://rox.sourceforge.net/2005/interfaces/ROX-Filer -S
#fi
I need this because I do not want to comment out every line containing "fi", just the "fi" of this specific if statement.
I'm trying to write a bash script to find all lines containing two different strings in many files. I don't have access to egrep so I want to use sed for this purpose.
The files will look like this:
FileX
------
Info:18
Data:76
Contact:me@home.com
Start:1500
I want to generate a new file from these files with only the rows containing Data and Start. Something like this:
for y in `ls /file*.db`;
do sed '/Data|Start/p' $y > newfile
done
I have some big files of logs that contain errors printed by an app. They are most of the time relevant, however most of them are similar. So i figured i could check what happened between a time interval with a find.
Im using this one
Code:
And I get an output similar to this one.
Code:
Is there a way to condensate the output lines to get only one or two, indicating the start and last occurrence of a block? Or I need to create a program to do so?
Because right now I get thousands of similar lines, but when I'm scrolling through them i sometimes miss relevant information that i would've otherwise noted if it wasn't all that spammy.
I've come across an unusual requirement for a service in my Ubuntu system.Simply put, I need to find a way to search for all instances of a term in a file, delete lines containing containing that term, and delete four lines below each instance of that term. ither that, or copy the entirety of a file to a new file and skip over all lines containing the term plus four below it.This sounds kinda weird, I know. Without going too far into detail, I either have to change the logfile format for a server I'm running which is a huge pain in the butt, or I can just run a script to edit an HTML report generated from said logs. (Said report is really just for managers to peruse, and I like my log format, so I'm pursuing option 2.)

View 7 Replies View RelatedI have a bunch of text files, all of them have a .txt extension. They are all located in subfolders of the /MyTextFiles folder (but could be anywhere, no idea what depth). If any line in any of the text files has the word "hello" I want to delete that entire line. I know sed and awk are made for this problem but I can't seem to get the syntax correct.
View 1 Replies View RelatedIs there a convenient method to find a text pattern that extends over several lines? In this case:
Empty line

Preferably to return the line number where the pattern occurs to determine the first such after a known line number. In other words, in order to extract a block of text from within a file.

I need to find a string in a file ... then delete the line it is on, as well as the next 6 lines. Or, delete the line the string is on and all subsequent lines until the search finds the character "["
example:
filename = test.txt
contents:
[foo]
test>test
test>test
test>test

so, in this example. I'd like to search the file for string 'foo' and delete all lines from that line until [bar] (not deleting the line with [bar])
I want to remove duplicate or multiple similar lines from multiple files. I.e. if I have four files file1.txt file2.txt file3.txt and file4.txt and would like to find and remove similar lines from all these files keeping only one line from these similar lines. I only that uniq can be used to remove similar lines from a sorted file.

So I want to print the items in a line and the next line in a single line.
For example:
I can print the line and the adjacent together and print the required items like this:

when I run the following command:

tmpfile displays the lines but they are all cut off and placed on the line below at the same point.

I have a file with a random word on each line (3k+ lines). How can I get the lines with only five characters? I tried using grep file | more, but it returns all the words (even those less than 5 characters).
Edit: I also tried grep '.{5}' file | more but it doesn't show anything. And grep '.{5}' file | more returns all lines with four or more characters (I'm really confused about why it's doing this).

I would like to use VIM to add something to the end of a series of lines. Ideally I could do something like add " X" (with a space before the X) to the end of lines 1-40 and 50-60 in a single command, i.e. ideally I could have a break in between where I didn't add something. If that's not possible just adding to 1-40 and 50-60 separately would work too. I would be using bufdo to do this, but my understanding is that anything you can do in vim you can use with the bufdo command.
View 3 Replies View RelatedI've cross compiled busybox with buildroot for the mini2440 (configured: arm920t EABI) I compiled it dynamically. I use Ubuntu 9.10 on my build system. Doing the "ls -l"-command in the /bin directory I see that busybox is marked red. (This is still on my build system, not on my target system!) The background of the word busybox is marked red. And the word busybox is in default colour instead of yellow, even though all permissions have the executable sign. I was wondering what this means. Also whether it's a bad thing? Also could this mean this is why my mini2440 will not boot correctly after transferring this root file system? (It stops the booting process just after loading the root file system)

As you can see two of the lines are commented out. However, both commented out commands are still running. I get emails stating that the RALUS agent restarted (another mystery since it's supposed to go to dev null according to the line above), and I can see that the memmon script is also running daily. Am I missing a step? Some other place I should be looking? Commenting out lines in your crontab is pretty much a no-brainer, so I appear to have less than no brain as this is a mystery to me.
