test.txt file:

Ext Temperatur:  210.0°
Avg.Speed(All):    62.89mm/s
Avg.Speed(Print):  49.99mm/s
Avg.Speed(Travel): 199.84mm/s
Overall Time (w/o Acceleration): 11:00:41 (39640.65sec)

How can I grab 62.89mm/s and 62.89 as outputs using grep and print with php code?

I am using this code but it prints the whole line e.g.: Avg.Speed(All): 62.89mm/s

<?php
$gcode_new = "grep -P 'Avg.Speed(All):' test.txt";

include('Net/SSH2.php');

$ssh = new Net_SSH2('XXX.61.XXX.227');
if (!$ssh->login('root', 'PASS')) {
    exit('Login Failed');
}
$target = $ssh->exec($gcode_new);

echo $target ;
?>

Question Update: How can i copy 11:00:41 from above data which is associated with "Overall Time (w/o Acceleration):" Tried to use the command which is suggested from answer, but receiving 11:00:41 (39640.65sec) here how can i avoid (39640.65sec). $ grep -Po '(?<=Overall Time \(w/o Acceleration\): ).*' testjar.txt

  • What operating system are you using? Do you have the GNU implementation of grep? Commented Apr 13, 2020 at 17:01

Use positive lookbehind assertion with GNU grep:

$ grep -Po '(?<=Avg.Speed\(All\):    ).*' test.txt
62.89mm/s
$ grep -Po '(?<=Avg.Speed\(All\):    )[0-9\.]+' test.txt
62.89

  • @testcod You are now changing the input data. Update your question or ask a new one. We don't really like follow-up questions in comments. Commented Apr 14, 2020 at 8:50

Using sed to grab 62.89mm/s from the example data by matching and deleting the start of the line:

sed -n 's/^Avg\.Speed(All):[[:blank:]]*//p' test.txt

To also strip the mm/s units off from the end (this strips any non-digits from the end):

sed -n '/^Avg\.Speed(All):[[:blank:]]*/{s///;s/[^[:digit:]]*$//p;}' test.txt

For the update question:

sed -n 's/^Overall Time.*\(..:..:..\).*/\1/p' file

This would extract the time string from the line starting with Overall Time in your data.

  • @testcod Use a simple command substitution? value=$(sed -n ...) Commented Apr 14, 2020 at 8:50
  • $jarext_5 = "sed -n 's/^Overall Time.*\(..:..:..\).*/\1/p' testjar.txt"; received ` ` as output Commented Apr 16, 2020 at 4:40
