Send to /dev/null a PHP function "echo" output

I wish this help you If you want get output to variable, you should use ob_start and ob_get_contents or ob_get_clean functions, example:
<?php
ob_start();
echo "Hello ";
$out1 = ob_get_contents();
echo "World";
$out2 = ob_get_contents();
ob_end_clean();

var_dump($out1, $out2);
/* 
string(6) "Hello "
string(11) "Hello World"
*/
<?php
ob_start();
echo "Hello ";
$out1 = ob_get_clean();

var_dump($out1);
/*
string(6) "Hello "
*/
<?php
ob_start();
echo '{"status":"OK","message":"Pong"}';
$out1 = ob_get_clean();

var_dump(json_decode($out1, true));
/*
array(2) {
  ["status"]=>
  string(2) "OK"
  ["message"]=>
  string(4) "Pong"
}
*/

Is it possible to forward the output of "service httpd restart" for example to "notify-send $output"

it should still fix some issue First, you really should look inside the terminal when running your script.
Also, notice that services are started before login time (at boot time).
  restart_msg=$(service httpd restart 2>&1)
  notify-send "HTTPD restarted" "$restart_msg"

Why does running "echo $-" output "himBH" on the bash shell?


Tag : bash , By : snk

To fix the issue you can do It shows your Builtin Set Flags. man bash then look for SHELL BUILTIN COMMANDS and then look for the set subsection. You will find the meanings of all those flags:
h: Remember the location of commands as they are looked up for execution.  This is enabled by default.
i: interactive
m: Monitor mode.  Job control is enabled
B: The shell performs brace expansion (see Brace Expansion above).  This is on by default
H: Enable !  style history substitution.  This option is on by default when the shell is interactive.

$ ssh -G 2>&1 | grep -e ille­gal -e un­known > /dev/null && echo "Sys­tem clean" || echo &qu
