While loop hangs in function running in background
Hello Everyone,
I am writing a shell script to fetch log files from remote servers within a time range. It copies log files to local server, grep for date and then compares the time stamp of each log entry with the once specified.
Below is the code.
I call the above function as shown below
When i run this, the while loop which is reading lines one by one in log file is not terminating once it reaches EOF.
I have tried running it in foreground (removing '&' while calling function) which works perfect.
I want to run it in background because there are 20 servers i need to ssh, scp and read log files which are more than 10 MB each.
Please suggest me if there are any changes needed in this code.
Hello all,
Can someone explain to me the advantage between using subshell over a function call in scripts? To me these are the same. Am I wrong to think this? (4 Replies)
consider the given prg.
main() {
.....
function1(); /* to write into a file or log */
printf(" ");
.....
}
when the control reaches function1(), it should get executed in the
background.At the same time main's printf(" ") statement should also get executed.i.e... (5 Replies)

Hello, I was trying to make some processes to run at background and went to a problem.
First I tried just to loop in one line something like this:
for i in {1..10}; do echo 'hello world' &; done;
but it pops a syntax error, so I tried several ways to fix it but wasn't able to understand... (2 Replies)
Here is some back ground on the script. The script is to poll an arbitrary number of DB's. To do this I am creating a function that takes the file_path to the DB and the min poll interval as arguments. The function will be called for each DB and then ran in the background. The function I was... (6 Replies)

rcsfreeze
rcsfreeze(1)rcsfreeze(1)NAME
rcsfreeze - freeze a configuration of sources checked in under RCS
SYNOPSIS
rcsfreeze [name]
DESCRIPTION
rcsfreeze assigns a symbolic revision number to a set of RCS files that form a valid configuration.
The idea is to run rcsfreeze each time a new version is checked in. A unique symbolic name (C_number, where number is increased each time
rcsfreeze is run) is then assigned to the most recent revision of each RCS file of the main trunk.
An optional name argument to rcsfreeze gives a symbolic name to the configuration. The unique identifier is still generated and is listed
in the log file but it will not appear as part of the symbolic revision name in the actual RCS files.
A log message is requested from the user for future reference.
The shell script works only on all RCS files at one time. All changed files must be checked in already. Run rcsclean(1) first and see
whether any sources remain in the current directory.
RESTRICTIONS
rcsfreeze does not check whether any sources are checked out and modified.
Although both source file names and RCS file names are accepted, they are not paired as usual with RCS commands.
Error checking is rudimentary.
rcsfreeze is just an optional example shell script, and should not be taken too seriously. See CVS for a more complete solution.
FILES
version number log messages, most recent first
