ksh: cmd output to input of another script

IMTheNachoMan · #1 (**permalink**) 04-26-2008

I want to write a script in KSH that takes the output of one command and redisplays it. Something like:

Code:

while true
do
	read inpt
	date +"%I:%M:%S %p <-> $inpt"
done

and then some how get the output of the ping command to redirect to the input of this script.

does that make sense?

Code:

ping -c 1 otherhost | while read inpt; do
  date +"%I:%M:%S %p <-> $input"
done

The -c 1 restricts this to one ping packet; if you want it to keep going, then certainly, just take out the "-c 1".

typo: inpt ---> input

Code:

ping -c 1 otherhost | while read input; do
  date +"%I:%M:%S %p <-> $input"
done

Also note that "%r" can be used instead of "%I:%M:%S %p" as in

Code:

ping -c 1 otherhost | while read input; do
  date +%r" <-> $input"
done
