I need to search a bunch of files in a specific folder for a specific number and add all the numbers together to a total sum. I use Rsync everyday, everytime I run rsync i get a logfile (rsync output) witch contains the textstring "Total bytes sent: xxxxxx".
The "xxxxx" can vary in lenght. I need to extract the "xxxxxx" from each file and add the numbers together to a total size over a week or a month. Is this possible? And I wish to only use bash. One way of doing stuff at a time my friends .
I want to replace specific character in a file after every specific line. example as follows.
O 000000000000000000
A 111111111111111111

I wanted to get the ORACLE_HOME of the listener's running on the server.I have been using the following to get the reult. /opt/oracle/admin/PHYPE/bdump> ps -ef|grep /bin/tnslsnr|grep -v grep|awk '{print $9}'
Result is as follows
/opt/oracle/product/10.2/bin/tnslsnr
/opt/oracle/product/9.2.0/bin/tnslsnr
/opt/oracle/product/10.2/bin/tnslsnr
/opt/oracle/product/10.2/bin/tnslsnr
/opt/oracle/product/9.2.0/bin/tnslsnr
/opt/oracle/product/10.2/bin/tnslsnr
Now i wanted to cut the /bin/tnslsnr part and the remaining should write to the file.
I have a variable (call it $valAS) that gets calculated . Also, i have a files Bassu3. if $valAS= 45368 (2nd part of 2nd line in Bassu3) after calculation, then $result=45368, but if $valAS != 45368 then $result= $valAS
Bassu3:
Quote:
name.srv
name 45368 (value always changing)
name 99999
name 88888
how can i do this in Bash?
I was wondering if I can show an image on our php site if we store the path to it. For example if we get the result form my sql as:
images/example1.png and the handle the result as common html.
< img src="databaseresult" width="173" height="188" border="1" / >
is this possible? do you think theres a better way to do it?
we need to store the images locally we cant use a blob space on the table.
It is under PHP/MySQL
$queryresult = $conn->query("INSERT INTO normalrequests VALUES($finalkey, 1234, 5678, FALSE)");
It is connected to the database successfully but I feel there is something wrong with the statement up there.
I'm trying to create a program that would locate the oldest file of a certain type on a server. Here's the commands:
OLDEST_PATH=`find -L / -depth -maxdepth 6 -mindepth 6 -type d | sort -f | head -1`
OLDEST_FILE=`find -L $OLDEST_PATH | grep .mp3 | sort -f | head -1`
ls -al $OLDEST_FILE
I'm writing this all in expect but I'm having problems. The main problem I have is whenever I try to run the first command, I can't seem to isolate the result of the OLDEST_PATH so that the 2nd command will work. There always seems to be a newline in the variable and the result is only "find -L" command running and it bypasses the variable. If I can just figure out how to get the 1st and 2nd command to work, then I can figure out the 3rd. Here's some code:
Code:
send "find -L / -depth -maxdepth 6 -mindepth 6 -type d | sort -f | head -1
"
sleep 20
expect -re "(.*)
[Code]....
I know there is a better way to write this. I've tried multiple ways and this just happens to be the last way I've tried it. If you try running this, you'll notice that there is still carriage returns after the result of OLDEST_PATH and it prevents the 2nd "find" command from working properly.
I am using the script below but need to make it to show the result in a html popup window. The script is Free and I don't think Kristina will complaint by making it more versatile.
The problem I have is that the script moves to a standalone window to show the results. I am interested in making it "popup' a window with the results.

I am new to perl and am having trouble adding some strings together.
My full code is below:
The problem is $NewCommandB is always split into two lines, where the second line contains the "/atlas2/<blah>/<etc>/..." string. Since I am generating a .sh file to execute a lot of similar commands I need the string to all be on one line. Any idea why I get this behaviour and any suggestion on how to tell perl to make $NewCommandB a one line string?
Btw for completeness finalFileList.txt contains just file names one line after another:
I am not sure if this is possible. I have IP's stored in a mysql database. When I query the database, it returns the IP. I would like to replace the IP with something else prior to displaying the results. Is it possible even though I have not stored it in the database?
I have the following in a while loop (mysql_fetch_array).
Code:
<td align="left">' . $row[IP] . '</td>
Instead of displaying $row[IP] from the database, I would like it to display something else which I define in the PHP code but based on the IP.
ie. aaa.bbb.ccc.ddd = hostnameABC
What i am trying to do is i want to add numbers from 1 to 100. but that too using multiprocessing. So i made a c programme and using fork() command made two child processes. Now in one child process i am adding from 1 to 50. and in another i am adding 51 to 100. and then in the parent process adding the two results to get the final one. Now the result from the two function i am getting correctly. But after the wait() call the value returned is lost : See the programme below for reference
# include<stdio.h>
# include<unistd.h>
# include<sys/wait.h>
# include<stdlib.h>

What I am trying to achive is the editing of /etc/ssh/sshd_config I have the line
Code: AllowUsers usera userb
And I want to be able to append to the end of this line from a bash script.I have muddled together from other sites and got the following:-
Code: sed -e "s/^AllowUsers/� userc/" -i /etc/ssh/sshd_config
But this appears to add userc directly after AllowUsers and not after userb

Is there a way to do it with awk?
I am loading variables for cXtXdXsX disk names into a script, and at present I have only accounted for there being 3 characters from c to t. I need to change it to a variable recognition so that it can count any number of charcters such as c1t , c10t , or c100t.
I can then take that information and use it with the following string to strip off the lead characters so as to make the 3 in $substr either a variable or redirect to multiple occurrences of raw based on the count returned.
sub raw {
$substr = substr ($_, 3);
$raw1 = substr ($substr, 0, -4);
$raw = lc($raw1);
}
how to count from the c to the t inclusive so I get 3, 4, 5, etc ...
These must a be a question you received a lot, but I couldn't find a similar thread! It's a simple question.
I need to delete a specific string from a file. For example the specific numbers "3456" from a file. I've tried with the tr comand, using
Code:
tr -d '3456' file,
but it also deleted whichever ocurrence of 3,4,5,6 from my file. Should I use a regular expression?
i need to overwrite each line of the file starting from a specific position to the end of the line
example:
ATOM 981 N PRO B 159 55.662 7 1 1.47 0.75
i need to write " 1.00 0.00 " starting from 20position
i tried
sed -i 's/^(.{20})*/ 1.00 0.00 ' filename
but it doesnt work :"(

I use rhythmbox to do download my podcasts and I'd really like to automatically sync the new files to my phone when I attach it.The phone mounts as an external drive so I was kind of hoping to write a script that would run automatically when the drive mounts.
I would want it to delete files on the phone that are not present on the computer.Can anyone help me with the syntax for both the bash part and the correct rsync command?
I want to compare 2 IP addresses, so that I may compare which is more/less "specific" or "restricted" than the other. So is there any function/library that may help in doing this comparison in C (on Ubuntu 10.10)?
View 1 Replies View RelatedI'm fairly new to Perl and regular expressions. I have a large collection of files with their file names in the following general format: string - another string with spaces (2004) [year].ext I would like to know how I could create a regex to separate out:

If you know of a better way of doing it without regular expressions, I would be happy to hear that way too.

As you can see i would like the output file to be just the dogs, not the otehr information. But because the information is mixed up how can i extract only the dogs? (i cant do and awk '{print }' because the dogs are found in colounm 2 or 3 or sometimes even 4.
To save on the writing of WAY to many files with very little in them, I want to put it all in one file and read a specific few lines. There will be six variables to be read at a time. Format is as such:

From name to 5th number is a set. The name will be of different lengths for each set. This will be a big file of probably 40+ sets. My problem lies in reading one and only one set be it set 5 or set 34. It needs to be done in C++.
I'm trying to come up with ideas for a simple way to strip a specific "entry" from a text file.I know tools like sed and perl can remove specific lines from a file but I haven't been able to come up with an elegant way to do my group of lines.In my file, the first "Location" line and the "SVNPath" line should be unique every time... but are they enough to strip out the whole set of the group plus the trailing one line of white space separating each group? Add to this, my file will grow as new entries are added (always appended to the end) but new entries will have the same formatting.
View 9 Replies View RelatedI need a shell script which gathers the data from a remote XML file and then displays it according to my needs.. I need this for my job due to the fact that I need to keep track price changes of euro, usd, gold, etc. The XML file I am talking about is located at this page: here. The reason I am posting the URL is that I need to use curl to get this file and it does NOT have newlines after each tag. I thought that that would be a problem. Here is what I need from the script: 1) curl to get the page 2) make use of sed, awk, etc. to display its contents in a more structured and readable manner as shown below:
