Top Forums Shell Programming and Scripting Curl and write custom result to file Post 303034404 by RudiC on Wednesday 24th of April 2019 06:01:51 PM
Good you found a solution on your own. How about some improvements? read the MyWebApps file in lieu of catting it in a "command substitution" (saves a process creation), write to the log file outside the loop (avoids opening / closing it over and over again), and combine five awk executions into one, like

while read i; do curl ...$i... | awk -F"[,/ ]" -vDT="$(date +"%Y-%m-%d-%H:%M")" -vOFS="," '{print DT, $7, $NF}'; done < MyWebApps > sessions.log

IO::Async::PID(3pm)					User Contributed Perl Documentation				       IO::Async::PID(3pm)

"IO::Async::PID" - event callback on exit of a child process SYNOPSIS
use IO::Async::PID; use POSIX qw( WEXITSTATUS ); use IO::Async::Loop; my $loop = IO::Async::Loop->new; my $kid = $loop->fork( code => sub { print "Child sleeping.. "; sleep 10; print "Child exiting "; return 20; }, ); print "Child process $kid started "; my $pid = IO::Async::PID->new( pid => $kid, on_exit => sub { my ( $self, $exitcode ) = @_; printf "Child process %d exited with status %d ", $self->pid, WEXITSTATUS($exitcode); }, ); $loop->add( $pid ); $loop->run; DESCRIPTION
This subclass of IO::Async::Notifier invokes its callback when a process exits. For most use cases, a IO::Async::Process object provides more control of setting up the process, connecting filehandles to it, sending data to and receiving data from it. EVENTS
The following events are invoked, either using subclass methods or CODE references in parameters: on_exit $exitcode Invoked when the watched process exits. PARAMETERS
The following named parameters may be passed to "new" or "configure": pid => INT The process ID to watch. Must be given before the object has been added to the containing "IO::Async::Loop" object. on_exit => CODE CODE reference for the "on_exit" event. Once the "on_exit" continuation has been invoked, the "IO::Async::PID" object is removed from the containing "IO::Async::Loop" object. METHODS
$process_id = $pid->pid Returns the underlying process ID $pid->kill( $signal ) Sends a signal to the process AUTHOR
