Programming :: Bash To Loop Through Mysql Select Array?
May 26, 2011I need to know how to assign a result from a select. I am clueless on the sytax. I am trying this in bash. Maybe I am not assigning the array right. It gives me the whole row in the echo instead of just field a. How do I get fieldA = a in the select. Note script was stripped for security on database info but the syntax is same.
Code:
#!/bin/sh
results="$(mysql --user ${DB_USER} -p${DB_PWD} ${DB_NAME} -Bse 'select a,b,c,d from tblMytable')"
for rows in "${results[@]}"
do
fieldA=${rows[0]};
echo ${fieldA};
done

Programming :: Bash/korn Script Rename Files To Same Name One At A Time?
Jun 23, 2009I have scowered the internet for the answer to this one. I need a script to rename multiple files to the same exact name, run a program on the file then do the same for the next file. We have a unix backend system that is expecting to load the file with the filename of cards.in So I will have files named card.2009xxx, like i said i will have around 4 or five of those. I want the script to rename card.2009xxx to cards.in, run our unix program on cards.in which inturn changes the file name and once complete i want the script to rename the next cards.2009 to "cards.in"Until there are no more left in the directory and the unix program has processed all the files. All of this is occurring in the same directory. I have written some scripts but they fail by moving for example cards.200901 to cards.in then immediately moving cards.200902 to cards.in and that is not good because it is overwriting valuable data

Feb 9, 2010I have a fallowing CGI script, which does nothing more than prints out the values user inserted:
Code:
If I insert Martin to the name box and 192.168.1.1 to the IP box I get fallowing output:
Quote:
Name is Martin
IP address is 192.168.1.1
As you can see, script above works fine(I host this script in Apache server and use Firefox as a web-client). Now I made a fallowing bash script:
Code:
Which is started like this: ./script.sh Martin 192.168.1.1. Output is user name plus port numbers and descriptions. This bash script works fine as well
How can I combine those two scripts? I would like to insert name and IP to according boxes in Firefox and after clicking Generate button, user name plus list of port numbers and descriptions will appear in Firefox window instead of terminal emulator window
How to link/combine those two scripts to work together as one?
Programming :: Clarification In The Select System Call?
Dec 8, 2010I 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..

View 8 Replies View RelatedProgramming :: Select() Waking Up With Rd_set On A Not Yet Connected Socket
Jun 24, 2010I'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.
