For my weather station I have made a little perl script to put the data into cacti. The next problem I have.
I can only get positive numbers or negative numbers.
What do I do:
Though a shell scrip I call the perl script.
Shell script:
Perl script:
Whith this input I can only get the negative numbers.
Like Buiten_t:-6.5
When I do:
I get only the positive numbers.
Buiten_t:28.6
If I let the
for the positive numnbers there is a space in the output.
The ouput is then Buiten_t: 28.6

Output like Buiten_t:-6.5 or Buiten_t:28.6

buiten_h : 89 %
--------Ground sensor-------------------
grond_t : -2.8 ▒C
grond_h : 89 %

[-+]* instead of \D+
assuming you always will have positive or negative numbers only. If you are sure that + is not used anywhere (which is the ideal case) just use [-]*
