Question

I’m not getting the result expect from the following code:

#!/bin/bash
cat /home/opmeitle/html/fiesta-one.html | grep -oiE '([$][0-9.]{1,7})'

this is output:

$90.850
$0
$389
$469
$670
$750
$684
$21.744
$604

Here is the result I desire, in console.

$90.850 $0 $389 $469 $670 $750 $684 $21.744 $604

I appreciate your answers. thanks

luis.

Answer 1

There are many other solutions:

$ echo $(grep -oiE '([$][0-9.]{1,7})' /home/opmeitle/html/fiesta-one.html)
$ grep -oiE '([$][0-9.]{1,7})' /home/opmeitle/html/fiesta-one.html | xargs echo
$ grep -oiE '([$][0-9.]{1,7})' /home/opmeitle/html/fiesta-one.html | tr '\n' ' '
$ grep -oiE '([$][0-9.]{1,7})' /home/opmeitle/html/fiesta-one.html | perl -pe 's/\n/ /;'

And without grep:

$ perl -ne 'print "$1 " if /([\$][0-9.]{1,7})/' /home/opmeitle/html/fiesta-one.html
