hi,
i am trying this while loop and i only want that it should only read food as pizza....no other entry should be taken here.
Code:
#!/usr/bin/perl -w
$food = " ";
while ( $food ne 'pizza' )
{
print 'enter what you had last night: ';
chomp ($food = <STDIN>);
#print $food ;
}
print "Mmm....it was yummy \n";
this is what the result i get after running this particular script, that the loop does not end and tht i have to terminate the session.
Code:
enter what you had last night: mango
enter what you had last night: pizza
enter what you had last night: tomato
enter what you had last night: potato
enter what you had last night:
this loop dpes not end as the way it should have ended.
thanks
kullu

REDSHIFT(1) User Commands REDSHIFT(1)NAME
redshift - Set color temperature of display according to time of day.
SYNOPSIS
redshift
-l LAT:LON -t DAY:NIGHT [OPTIONS...]
DESCRIPTION
redshift adjusts the color temperature of your screen according to your surroundings. This may help your eyes hurt less if you are working
in front of the screen at night.
The color temperature is set according to the position of the sun. A different color temperature is set during night and daytime. During
twilight and early morning, the color temperature transitions smoothly from night to daytime temperature to allow your eyes to slowly
adapt.
OPTIONS -h Display this help message
-v Verbose output
-V Show program version
-b N Screen brightness to apply (max is 1.0)
-c FILE
Load settings from specified configuration file
-g R:G:B
Additional gamma correction to apply
-l LAT:LON
Your current location
-l PROVIDER
Select provider for automatic location updates (Type `list' to see available providers)
-m METHOD
Method to use to set color temperature (Type `list' to see available methods)
-o One shot mode (do not continuously adjust color temperature)
-O TEMP
One shot manual mode (set color temperature)
-x Reset mode (remove adjustment from screen)
-r Disable temperature transitions
-t DAY:NIGHT
Color temperature to set at daytime/night
The neutral temperature is 6500K. Using this value will not change the color temperature of the display. Setting the color temperature to a
value higher than this results in more blue light, and setting a lower value will result in more red light.
Default values:
Daytime temperature: 5500K Night temperature: 3700K
