As i am new to C++ i couldn't figure out how to input a file and make some change on the file and produce a output file. like this problem i have is.
"Program that processes an input file and produces an output file. The input file will contain lines of data, each containing two floating point numbers. The lines of the output file should contain the two numbers read and their average (with a '$' sign and 2 places after the decimal point)."
With the command "tail -300 /var/log/apache2/access.log | less" i can look in the log for the 300 latest visitors. and i wanted to ask if it's possiblle to get that command to run from a php file and if yes how ?

See the first program below :
Code:
This code when compiled gives the following errors:
1. conflicting types for 'fun' at line no: 9
2. previous declaration of 'fun' was here at line no: 3
Why is this happening?
If i modify the above program as shown in the second program below:

Why the difference occurs between the first and second program?

I have a script that generates a bunch of output, including the expansions details provided by: set -v -xI am trying to pipe everything that is displayed to a file, in addition to displaying it on the screen. I've managed to get stderr and stdout into the file, but the expansions are only printed to the screen. Here is what I have so far:sudo -u <user> source my_job.sh |tee my_log.txt 2>&1
View 2 Replies View RelatedI am again struggling to make a script work, but hey, it is fun, I am learning new things. I discovered the set -x option which was, for me, like the second coming. Still, what I am not able to do is redirect ALL output to a (log) file, including what is produced by the -x setting. Let's assume a very simple script:
Code: #!/bin/bash
set -x
source="/home/atelier/Bureau/"
ls -la $source and I am running it as . test.sh >> /var/log/test.rmcb.log
The result of ls goes inded into the log file, but the rest still shows on the console where I am running the script: Code: ++ source=/home/atelier/Bureau/
++ ls --color=auto -la /home/atelier/Bureau/ Is there a way to redirect EVERYTHING to the log file ?
I need to re-direct the output within an awk script, but not to already known, fixed filenames. The output file names depend on values of the fields. For example (the actual problem is surely more complicated), if, on a given line, the second field is DATA, the third is 1984, I would like to print some information in a file called output_DATA_1984. This could/would change in the following line of the same input file. Such things are pretty easy in bash, put I cannot do it in awk, as I can only find manual references for redirecting output to fixed filenames between double quotes.
View 2 Replies View Relatedi'm programming a small widget for a panel and need some information from my system. The command on the shell would be whoami to find out which user i am. This information is needed for my widget to set up the title of the widget, the information of the user will be retrieved out of the /etc/passwd (the code works just fine), but i don't know how i can get the information. One possibility would be to create a child process, call whoami with execlp(). But how can i retrieve the output of that process?
View 3 Replies View RelatedHow 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.

View 1 Replies View RelatedI am trying to use a shell script to find a string in a file and do something when found. code...
What should happen is pppd will start in a different process and stream it's output to pppdout. pppdout should be created in the current folder. Then the script should periodically check the pppdout file for the string Script (which eventually will appear, some seconds later) and when found exit the script. Ultimately the script will do something useful when the text is found. However, the output from the program is a repeating: 'scriptname.sh: 12: FOUND: not found'
Where scriptname.sh would be the name of your script and 12 refers to the line with 'done'.
Why does grep not find the text, or at least why deos my script not check the grep output correctly?

View 4 Replies View RelatedNew to ubuntu and shell scripting in general... currently I stored some data into a text file. Right now, I would like to output the data from the text file and store it into a variable. Here's what I have so far:
READ_FILE=$(cat $FILE_NAME)
This definitely works and READ_FILE has the necessary data. However, this command will trigger an output to std output and I will see data on the screen, which is not what I want. I tried:
cat $FILE_NAME | $READ_FILE
and various other variants of this. It does not output to std output but neither does anything gets stored into $READ_FILE. I tried:

I'm testing some multi-plat java code and I'm getting a bit frustrated with the Linux tests. I need to run the command:
Code:
$ java -jar /home/developer/TCO/TabletComicOptimizer.jar <file> <args[]>
against all the files that match a specific criteria. I've tried various find syntax and I can't seem to get it right.
Normally I would just create a bash script and populate the results of find into an array and then just enumerate the collection but in this specific case I want to demonstrate this operation at the bash terminal.
I've tried things like:
Code:
~/TCO $ find . -type f -iname "*.cb[rz]" | xargs java -jar TabletComicOptimizer.jar {} 1200x1800 ;
Thinking that the {} is the substitution for each file returned by find but it's not working. How do I execute my java program against each result in the find operation?

I want to have the output of a program go to 2 different files but not going to standard out. Is there a way to do this in bash? I know that in Z shell its really easy. omething like: Code: echo "test" >> file1 >> file2 Would work. But in Bash it doesn't seem that easy. I know that tee will send the output to 2 files but it also sends it to STDOUT.Something like:Code: echo "test" | tee -a file1 file2 Would put the word "test" in file1, file2, and STDOUT. Is there a way to just send the output to file1 and file2?

I would really like to capture the output of scp and my file's progress. Scp updates the transfer rate every 1 second, and I will like to save the transfer rate at every update. So for example, if the file transfer takes 30 seconds, I would like 30 reports of the transfer rate.
The output looks like:
Code:
file.dat 1% 3664KB 938.5KB/s 05:48
Whenever I try a simple redirect like:
Code:
scp file.dat 192.168.1.100:~/ &> output
... it does not save the rate at every update, it only shows the final rate.
If I try using typescript by starting "script" ... it's the same deal.

I'm troubleshooting a batch of scripts I'm modifying, including an IDL script called by a .csh script. the IDL scripts were provided to me by a coworker and my .csh script is intended to automate a lengthy set of extremely tedious and time consuming processing tasks.
I am currently in the process of debugging, and can't get the IDL to print any messages other than critical failures to the screen. Is there any easy way to redirect the stdout to either a logfile or the screen?
