But as you can see in the input, in the 2nd "Event", the line containing "age" is not present, but in the output my code is printing the 1rst age value twice. The correct output should be blank in the age field for 2nd line in the output like this:
I'm trying to read content of file to variable and use this variable in for loop. The problem is, when I have c++ comment style in file - /*. Spaces in line are also interpreted as separated lines.
For example:
Code:
Changing $files to "$files" eliminate these problems but causes that whole content of variable is treated as one string (one execution of loop).
my script has a variable which comes in the form +00.00 +0.00 -00.00 or -0.00 (the numbers can be any in that form) for any that have a + symbol I need to remove the +, but if it has a - symbol it needs to stay.
i need to make a new variable with the string from the old variable btut without any plus sign. I have tried a lot of different ways with no success, each thing I tried either left the + or removed the entire string. I think this should work but doesn't
I have faced a problem with my code (a small tcp server). After the thread returns, the memory not decreases, but when a new connection is made, memory not increases and the new connection initialize a new thread with a same thread id of the previous thread. When two connections are made at same time, two thread ids are created and when the respective threads returns the memory not decreases. The Valgrind indicates that not memory leak occurs, the pointers are released. Indeed, more memory are allocate when new thread id is created. i used gcc and debian.
I have a C++ application consisting of several source/header files. As part of the release management procedure, I use a shell script to package all necessary sources/headers in a tar file for a successful compilation on end-user site.However, for example, each time a new directory is created within application's source tree, I need to edit the shell script to implement necessary changes, which is error-prone.What is the best practice to package the source/header files of an application into a tar file ? Is there any tool that I can use for packaging purposes rather than writing my own shell scripts ? For example, how is Linux kernel itself packaged into a tar file ?
After doing make I have the following questions? How can I see that the build is with debug information? What shall I do to build the release version? Can I have the release version in one directory and the debug version in another? I mean, when I change from debug to release, make will not overwrite the debug version.
I'm pretty new subversion, and have a basic question which I haven't found the answer to:Say that I on machine A modify the working copy of my code, create a tag "release-1.0", and commit it, how can I on machine B point the working copy to the tagged code? For example, say my "code" is actually config files for Apache, and I wan't apache running on machine B to update it's config files based on the files found in tag "release-1.0", how is this done?
I'm sure the solution is very easy, but I just can wrap my head around it.
I need to replace JAVA_OPTS= with JAVA_OPTS=<some_value>.I need to give "" value at the end of the replacement. I have tried with the following but it is not working: sed -e "s|JAVA_OPTS= |JAVA_OPTS=<some_value>"
how shall I print each variable separately using a generalized form. I tried writing the following within a for loop...Code:echo $(echo a$(echo $i)$(echo $j))which did yield no result. So what shall I write??
i'm trying to execute a shell script, i'm trying to use the values in an array for use in a sed command:
sed -n '/Sales ID: ${array[$i]}/,/Totals:/p'
that command creates empty files. so my guess is that its not recognizing the array as an array but as text? how would i be able to utilize the array in the command? i got it, didnt think that if i doubled up the single quotes that it would work, but this worked:
It compiles fine, but gets stuck in the loop. z never increments. I was using a for loop originally but had the same problem so I decided to try a while loop.
Just a simple BASH for loop to read the file path from a text file (clean.txt) echo the variable for debug purposes, and scp it to a server I have using port 50 for SSH.
I've already formatted the entries in clean.txt to handle spaces correctly, using sed replacement.
Example from the clean.txt file:
Code: /MP3/NAS000000001/Barenaked Ladies/Barenaked Ladies - Barenaked For The Holidays/20 Auld Lang Syne.mp3 /MP3/NAS000000001/Barenaked Ladies/Barenaked Ladies - Barenaked For The Holidays/14 Deck the Stills.mp3
I am trying to create a script to be used on RHEL server. If I replace the $t with a number, the script works. If I try add a variable or the $1, the script doesn?t work (returns all processes even if less than the $t value). I thought that it may be treating it as a literal, but I wasn?t sure of the conversion.
I am trying to write a script which can read the names of all folders within a given folder into separate variables. In effect, if a folder contains a folder "Folder1", "Folder2", "Folder3", the script would read those names into variables such as:
I am new to linux scripting, but I have programming experience. I need to save the UUID for /dev/sda1 as a variable, lets call it id. I am sure there is a way to do this with the awk and blkid commands, but I do not know any of this well enough yet to figure it out and after a couple of hours of reading I am still lost as to exactly how I would put this together. I need to save the uuid as a variable so that I can run an if statement with it
if [ -f /media/$id/file ] then echo "copy successful" else echo "oh crap!"
honestly all I need the uuid for but I cant check this by doing the same if with /dev/sda1/file so I need to be able to save the uuid into a variable
I want to write a c program with some shell scripts.Now For a simple C program. I am Setting a variable called val2 in bash, now I want to use bash variable val2 in C code. How do I do that?The above doesn't work (coz its spawning a different memory space and when shell script ends the variable dies with it as per my research but how do I keep them in same memory space)Also Is there any Good reference where they teach how to integrate C and Bash Together?
