I'm using PERL on windows NT to try to run an extract of data. I have multiple zip files in multiple locations. I am extracting "*.t" from zip files and subsequently adding that file to one zip file so when the script is complete I should have one zip file with a whole bunch of ".t" files in it.

When running a command using the >(cmd) syntax in bash how do you wait for the command to complete before moving on in your script?
Here is a simple example:

Let's say I start process A.sh, then start process B.sh. I call both of them in my C.sh
How can I make sure that B starts its execution only after A.sh finishes.
I have to do this in loop.Execution time of A.sh may vary everytime.
It is a parameterized script. (17 Replies)

ntp-wait - Wait for ntpd to stabilize the system clock
SYNOPSIS
ntp-wait [-flags] [-flag [value]] [--option-name[[=| ]value]]
All arguments must be options.
DESCRIPTION
ntp-wait will send at most num-tries queries to ntpd(8), sleeping for secs-between-tries after each status return that says ntpd(8) has not
yet produced a synchronized and stable system clock.
ntp-wait will do this quietly, unless the -v flag is provided. This can be useful at boot time, to delay the boot sequence until after
ntpd -g has set the time.
OPTIONS -n number, --tries=number
Number of times to check ntpd. This option takes an integer number as its argument. The default number for this option is:
100
The maximum number of times we will check ntpd to see if
it has been able to synchronize and stabilize the system clock.
-s secs-between-tries, --sleep=secs-between-tries
How long to sleep between tries. This option takes an integer number as its argument. The default secs-between-tries for this
option is:
6
We will sleep for secs-between-tries after each query
of ntpd that returns "the time is not yet stable".
-v, --verbose
Be verbose.
By default, ntp-wait is silent.
With this option, ntp-wait will provide status information.
-?, --help
Display usage information and exit.
-!, --more-help
Pass the extended usage information through a pager.
-v [{v|c|n --version [{v|c|n}]}]
Output version of program and exit. The default mode is `v', a simple version. The `c' mode will print copyright information and
`n' will print the full copyright notice.
EXIT STATUS
One of the following exit values will be returned:
0 (EXIT_SUCCESS)
Successful program execution.
1 (EXIT_FAILURE)
The operation failed or the command syntax was not valid.
70 (EX_SOFTWARE)
libopts had an internal operational error. Please report it to autogen-users@lists.sourceforge.net. Thank you.
