I have a bash script that checks for contents in a folder every 15 seconds and then acts on it's contents. This works great for the average size file however on very large files it starts acting on the file before it's completely written. Is there a facility in bash shell to get a file complete signal or such? here is trigger to launch a larger script.
Code:
#!/bin/sh
while true

I am trying to write a bash script that sources another bash script. Essentially, I need a few lines to check to see if a certain variable is set. If not, I set it manually, and then source a scripts with that variable in the path. I wrote a test script to try it, but for some reason the last line does not work. Here is what I wrote:
#!/bin/sh
source ~setupdir/setup.shrc #just a test, this line works
echo ${#SETUP} # prints 0 if setup is not set, which it isn't
if [ ${#SETUP} -eq 0 ]
then
SETUP="~setupdir"
fi
echo $SETUP # prints ~setupdir

- nothing returned (good). Then I change the time

I have a bash script that is tracking ERROR connections (running in a cron every 15 minutes), sometimes the errors are true and are not connecting. But most of the time, the disconnects/reconnects are between 30 seconds are sending out false positives. I am looking for a time comparison code to pick out the 30 second disconnects and know that this is and "ok" error. Here is a section of the log with timestamps, errors, etc.

I 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

Iam using socket programming in one of my problem. The scenario is like this.
=>one module is working as a socket server(process p1) is able to handle client sockets on that port.
=>one module is working as socket client (process p2) is connected to server socket and Tx/Rx data on this socket. This module has some more threads, based on received data from server socket it will connect to http on other thread and get information...
=>one more module is working as socket client (process p3) is also connected to server socket and doing some other transactions.
Here my problem is when in presence of p2, p3 http connection taking more time than the expected. If we wont start p3(means only one server-client socket) then http connection is fast enough.
I'm starting to like making bash scripts. It's kewl making creative ones. Right now I'm trying to make a bash script that will open up port 23 for a netcat connection.

I am using ubuntu 8.04.When I install software from internet then files are downloaded to /var/cache/apt/archives so i keep those debian files in safe place so that I can install that software on another stand-alone computer.
MY question: When we run 'apt-get update' for first time after fresh install it downloads some files. Can i store those files & point to them for a networkless computer which has no internet ? If this is possible it will allow me to 'apt-get check' on stand-alone computer to see if any package is not proper.
