I have written many awk commands which go in multiple lines.
I have this confusion many times.
Some time they work if i dont terminate them with "\" but some time error.
Some time in "if" statements between if and else if i dont use ";" it gives error but sometimes it doesnt.
The below code if i dont use ";" it gives error.
In the below code i am not using ";" between if and else if but it works
Appreciate help in clarifing where to use ";" and "\'

I basically want it to return 'failedhost.com' but its just showing the output of the nmap scan. (8 Replies)

times
times(1) User Commands times(1)NAME
times - shell built-in function to report time usages of the current shell
SYNOPSIS
sh
times
ksh
times
DESCRIPTION
sh
Print the accumulated user and system times for processes run from the shell.
ksh
Print the accumulated user and system times for the shell and for processes run from the shell.
On this man page, ksh(1) commands that are preceded by one or two * (asterisks) are treated specially in the following ways:
1. Variable assignment lists preceding the command remain in effect when the command completes.
2. I/O redirections are processed after variable assignments.
3. Errors cause a script that contains them to abort.
4. Words, following a command preceded by ** that are in the format of a variable assignment, are expanded with the same rules as a vari-
able assignment. This means that tilde substitution is performed after the = sign and word splitting and file name generation are not
performed.
