I would like to loop through a set of directories, performing operation(s) on each one. The basic script** is
Code:
dirs=`find . -name .svn -print`
for f in $dirs; do
echo "Processing $f directory .."
done
Fine and dandy, but here is the problem: the find expression must complete before the do ... done begins. The find process is relatively slow. I would like to have the do .. done work on entries as they are appended to the list. So in essence there are two threads, the find works in the background, and the do consumes $dirs until empty.
How would the do .. done loop "know" that the $dirs is still being populated? Maybe this needs to be changed completely using another method.
Thanks in advance.
** Some of you will recognize the ".svn", as Subversion stores additional copies of data on the local machine in ".svn" directories.

Hi all,
I have an Producer/Consumer program in C(using shared memory and semaphores).It is working fine with sleep calls after every read/write operation.Each one is a independent program.Now if i remove the sleep calls in consumer,it goes on waiting in the loop till the producer puts some valid...

The intention of the program. Create N threads with 2 shared memories.
One shared memory to write, one shared memory to recieve.
Consumer creates 2 shared memory to share with producer.
I need H threads for the producer as well(somebody help on it..)
Also another question, would segment_id... (2 Replies)

Control two exclusively shared resources. The two resources are two files. The producer will write even numbers to one file, and odd numbers to another one. The consumer respectively reads from each file until it gets 5 even numbers and 5 odd numbers.
Can any one help me with the code.

svnpath
SVNPATH(1)SVNPATH(1)NAME
svnpath - output svn url with support for tags and branches
SYNOPSIS
svnpath
svnpath tags
svnpath branches
svnpath trunk
DESCRIPTION
svnpath is intended to be run in a Subversion working copy.
In its simplest usage, svnpath with no parameters outputs the svn url for the repository associated with the working copy.
If a parameter is given, svnpath attempts to instead output the url that would be used for the tags, branches, or trunk. This will only
work if it's run in the top-level directory that is subject to tagging or branching.
For example, if you want to tag what's checked into Subversion as version 1.0, you could use a command like this:
svn cp $(svnpath) $(svnpath tags)/1.0
That's much easier than using svn info to look up the repository url and manually modifying it to derive the url to use for the tag, and
typing in something like this:
svn cp svn+ssh://my.server.example/svn/project/trunk svn+ssh://my.server.example/svn/project/tags/1.0
svnpath uses a simple heuristic to convert between the trunk, tags, and branches paths. It replaces the first occurrence of trunk, tags, or
branches with the name of what you're looking for. This will work ok for most typical Subversion repository layouts.
If you have an atypical layout and it does not work, you can add a ~/.svnpath file. This file is perl code, which can modify the path in
$url. For example, the author uses this file:
#!/usr/bin/perl
# svnpath personal override file
# For d-i I sometimes work from a full d-i tree branch. Remove that from
# the path to get regular tags or branches directories.
$url=~s!d-i/(rc|beta)[0-9]+/!!;
$url=~s!d-i/sarge/!!;
