Hello friends,
i wrote a script which includes a couple of if-else loops but i have to change it to while-do loop as it is not allowed to use "break" in if-else loop in bash.
#!/bin/bash -x
NUM=`find . -name ufsdump_output1.txt | xargs egrep "End-of-tape detected"`
if ; then echo "OK!"... (6 Replies)
i am new to shell scripting. this is similar to the code which i was writing for some other work. i want the variable 'x' to have the value which it will finally have at the end of the loop ( the number of directories ). but the value of 'x' only changes inside the loop and it remains '0' out-side...

Simple enough problem I think, I just can't seem to get it right.
The below doesn't work as intended, it's just a function defined in a much larger script:
CheckValues() {

Group_Title \

I have a group of variables myLINEcnt1 - myLINEcnt10. I'm trying to printout the values using a for loop. I am at the head banging stage since i'm sure it has to be a basic syntax issue that i can't figure out.

Hi guys, i have an executable file that contains several records and fields. One of the records has a variable filed that must be changed each time i want to execute the file. Would it be possible that i can use a loop to change the value of that field? Suppose that the field address is:

Hi, I have an N number of files in a directory. I like to write a shell script that would make identical plots for each one of these files.

Hi All,

io::async::timer::absolute
IO::Async::Timer::Absolute(3pm) User Contributed Perl Documentation IO::Async::Timer::Absolute(3pm)NAME
"IO::Async::Timer::Absolute" - event callback at a fixed future time
SYNOPSIS
use IO::Async::Timer::Absolute;
use POSIX qw( mktime );
use IO::Async::Loop;
my $loop = IO::Async::Loop->new;
my @time = gmtime;
my $timer = IO::Async::Timer::Absolute->new(
time => mktime( 0, 0, 0, $time[4]+1, $time[5], $time[6] ),
on_expire => sub {
print "It's midnight
";
$loop->stop;
},
);
$loop->add( $timer );
$loop->run;
DESCRIPTION
This subclass of IO::Async::Timer implements one-shot events at a fixed time in the future. The object waits for a given timestamp, and
invokes its callback at that point in the future.
For a "Timer" object that waits for a delay relative to the time it is started, see instead IO::Async::Timer::Countdown.
EVENTS
The following events are invoked, either using subclass methods or CODE references in parameters:
on_expire
Invoked when the timer expires.
PARAMETERS
The following named parameters may be passed to "new" or "configure":
on_expire => CODE
CODE reference for the "on_expire" event.
time => NUM
The epoch time at which the timer will expire.
Once constructed, the timer object will need to be added to the "Loop" before it will work.
Unlike other timers, it does not make sense to "start" this object, because its expiry time is absolute, and not relative to the time it is
started.
