Go to a line of code , skip few lines of code
Hi ,

I have a code where i am using a infinite while loop . some thing like below

Code:
while [ 2 -gt 1 ]
do

if [ logic ]
then
#go to line 20 

fi
command 1;


command 2;

#line 20:
sleep 34;
done;


Now i want that if my logic enters the if loop it should go directly to sleep 34 ; and i.e. skip command 1 and command 2 .

Can anyone suggest something .

There are 2 options:

1. Call a function that runs sleep command
Code:
sleep_func()
{
  sleep 34
}
if [ logic ]
then
 sleep_func
fi

2. Call sleep inside the if condition itself:-
Code:
if [ logic ]
then
 sleep 34
fi

I don't think there is goto statement available in most shells except for tcsh But using it is considered as a bad programming practice.

Why don't you put the commands inside the else construct of if statement?
Code:
if [ logic ]
then
 sleep 34
else
 command 1
 command 2
fi

Hi ,

Yes , i know its a bad programming practice but i was trying to find it out on bash , may be its not available on bash .

I am sure , if / else will solve this .

Thank You Smilie
