I want to select the branch based on the INPUT. Here is the program segment which uses the case statement.
case $INPUT in
1)branch="Computer Science";;
2)branch ="Electrical";;
3)branch = "Mechanical";;
4)branch= "Aerospace";;
esac
When I run this script, I am getting an error, Electrical command not found?
I'm trying to call a specific variable based on a user selection. For example:
Code: Select a file:
[1] foo.tar
[2] bar.tar
Enter a selection: I have already coded each possible selection to have its own variable. If the user selects 2 I need to select $SELECTED_TAR2, or if they select 1 I need to select $SELECTED_TAR1 and then do something like this behind the scenes:
Code: cp /home/user/$SELECTED_TAR2 /home/user/backup/$SELECTED_TAR2
I was thinking something like this:
Code: echo "Enter a selection: "
read -e SELECTED_NUMBER
cp /home/user/$SELECTED_TAR$SELECTED_NUMBER /home/user/backup

I am splitting a file based on the values read from an input file. The below one is the script.
1)How do I add the header which is present in the original file to the new split files created?(For eg. pharmacyf conatins header as table column names. The new files created (ODS.POS.$pharmacyid.$tablename.$CURRENT_DATE.dat) are without the header).
2) Also the script is creating 0 byte files for the pharmacyids which are not available in the intial file? Can this be avoided?
for pharmacyf in *
do
tablename=`echo $pharmacyf |cut -f4 -d'.' `
while read pharmacyid
do
grep -w $pharmacyid $pharmacyf >> $OUT/ODS.POS.$pharmacyid.$tablename.$CURRENT_DATE.dat
done< inputfile
done

View 1 Replies View RelatedI want to select lines from FileA based on a key field in FileB.
egrep does this nicely:
"egrep -w '0132874|0132880|0100765' < " FileA
Suppose FileB consists of three lines:
0132874
0132880
0100765
Is there a way to code egrep to do the selection? I really like code which does not use explicit loops so my interest is to find a grep or egrep or sed (or some other) command to perform this function.
Neither file is sorted on the key field but they could be. There is no requirement to keep the files in their present order.We may assume that each key value in each file is unique.
I use a USB webcam with a built in microphone. It works fine, but every time I plug it in I have to go to sound properties and select it as the input device. There are no other input devices present on my system. Since it's the only one there, is there any way to get it to automatically select when I plug it in? If not, I think that would be good functionality to add. Does anyone know who or what team to contact about that?

I need to route or forward traffic to and output interface based on the physical interface and source IP address in the packet.I have multiple ip rules to send traffic to custom routing tables and each of those custom tables had a default route out the appropriate interface, but traffic isn't flowing. Afterwards I tried using iptables and put an ACCEPT any statement in every chain of every table. What am I missing, ebtables maybe??

I have a general idea of how this should work, but no idea what tools and commands to use to implement it.
I have currently had the need to go back to basic socket programming, and implemented a simple udp packet sender. But I realized I needed to be able to select which network interface to send the packets from.
The reason is so that one of the interfaces has vlan tagging, and I need my UDP packets to be accordingly vlan tagged. For example, one of the interfaces is eth1.200.

I have a process that forks, where the childs puts some data of random size and exits while the parent should get the data and does some manipulation.. here I have used a pipe for child to write the data and parent to read the data.. Child simply dumps the data, and the data is of any size even child and parent doesnt know.
I have used select in the parent to see whether there is any data coming on the reading end of the pipe.. if there is a data.. I copy into a buffer.. Im reading the data continusly when the child exits after closing the writing end of pipe. Parent gets blocked on the read part But my question is how parent know the other of pipe is closed when using the select call. In otherwords.. while using select in readfds, how would i know the other end has closed the pipe..

Basically like this:

I'm trying to make a very small script with greasemonkey to do some automatic things when a page loads. The first thing I need to do is to click on a link. I've done that. Then I need to select the 3rd element of a drop down list that appears a few moments (depending on the connection) after the link is pressed, without reloading the page (ajax or something like that). This I can't get to work, The select has no id or class, but I can get its xpath value. There is only one select on the page. I've tried both setTimeOut and the DOMNodeInserted event with no effect.
Code:
// ==UserScript==
// @name test
// @namespace "www.google.com"
// @include www.mywebpage.com

I'm facing a strange problem with our code. What the program does is to wait on a select() after a non-blocking connect. And I expect the select wake up with write_set after the ESTAB. And I expect select wakeup with both rd_set and wr_set if I recv a RST back for our SYN or any similar errors. But in one of the cases I'm seeing select is waking up with only rd_set in a non-connected sockeet, which is causing a lot of problems for me.
The code is organized such that the socket close() happens only in wr_set processing. Because of that with the above problem I'm going in to a strange scenario. After the event I call select() again and wait for another socket event. But with this issue, my select is waking up there after everytime as soon as I call select(). That too only with rd_set. So it keeps on going with select() sleeping 0 secs. Thus the program is hung and eating lot of CPU cycles also.
The trigger for all these problems seems to be some event which causes the waking up of select() with rd_set only. I tried many ways to find out what is happening with this. Couldn't find anything interesting yet.
I am using C++ with SQLite db in a program that will read read a sub set of records, compare records and write different records to another database. I have a SQLite book, but it only shows examples for the C API. Anyone have code samples in C++ for the following:

View 1 Replies View RelatedQuote: Security expert Georgi Guninski has pointed out a security issue in the 1.0 branch of OpenSSL that potentially allows SSL servers to compromise clients. Apparently the hole can be exploited simply by sending a specially crafted certificate to the client, causing deallocated memory to be accessed in the ssl3_get_key_exchange function (in ssls3_clnt.c). While this usually only causes an application to crash, it can potentially also be exploited to execute injected code.

I am new to git (and storing multiple copies of my code).
I was using git for one month (git status, git add, git commit) to store my files.
I have problems to add more files to my branch
git add BasisExpansion.R
fatal: Unable to write new index file
this was working great unless the day my system administrator destroyed my main partition (it was an accident) and installed everything from scratch. My home directory stayed intact (I did not lose any files not git files that are stored under /home). But from this point of time git returns always that error. My system administrator creater the same user and group as my old user was but this didnot fix the problem.
I am not sure If I can recover my old git structure or would it be better to wipe out the old git dir and start a new one?
