Re: How to check my conditions....!!!

a simple if statment will work

this isnt the syntax but just a clue!

if data > one && data < two
then
do something
else
do something else
fi

Re: How to check my conditions....!!!

Another suggestion - since it looks like you are comparing military time, it will be easier to make the comparison if you drop the ":".

You can do this with sed or tr or even cut very easily.
After that, you can do the if comparison. Otherwise you will need to use cut to break each time into two integers for comparison with three logics!

Re: How to check my conditions....!!!

Okay, I needed something to get my mind off work for a few minutes, so here's a quick script I wrote using both of the suggestions above from chris5126 and omrsafetyo. I didn't translate the date, I used the date command to format the date without colons. Here goes, hope it helps!

Shell Scripting Syntax (Toggle Plain Text)
  1. #!/bin/sh
  2.  
  3. one=143300
  4. two=143400
  5.  
  6. while true; do
  7.  
  8.   time="$(date +%H%M%S)"
  9.  
  10.   if [ $time -gt $one ] && [ $time -lt $two ]; then
  11.     echo "$time We're in the zone\!"
  12.  
  13.   elif [ $time -gt $one ] && [ $time -gt $two ]; then
  14.     echo "$time The time has passed"
  15.  
  16.   elif [ $time -lt $one ] && [ $time -lt $two ]; then
  17.     echo "$time It's not time yet..."
  18.   fi
  19.  
  20.   sleep 10
  21.  
  22. done

And here's the output:

Shell Scripting Syntax (Toggle Plain Text)
  1. $ sh ./timecompare.sh 
  2. 143204 It's not time yet...
  3. 143214 It's not time yet...
  4. 143224 It's not time yet...
  5. 143234 It's not time yet...
  6. 143244 It's not time yet...
  7. 143254 It's not time yet...
  8. 143304 We're in the zone\!
  9. 143314 We're in the zone\!
  10. 143324 We're in the zone\!
  11. 143334 We're in the zone\!
  12. 143344 We're in the zone\!
  13. 143354 We're in the zone\!
  14. 143404 The time has passed
  15. 143414 The time has passed

Enjoy!
