Exit for loop in a shell script if a condition is successfull
Hi All,
I am stuch in a script where a for loop is running to execute some commands for some values.
Now my problem is i have to have an if condition that if the first iteration is successful then it has to exit the for loop otherwise it has to continue normally.
my code is this:
What i have tried so far is
but it is not working.
I have other way
like this
but this will not help as the line
will execute even if
will not return any value.
My requirement is the for loop should execute only once if for the first iteration
the above line produces an out put.
If the above line produces an output for the first iteration then there is no need of doing further iteration and it should exit the for loop else it should continue executing the loop.
Hi,

Manually this script is running fine & files are getting transferred.
But running the same script using crontab does not transfer files, although the cron log shows that the file was executed.

LEARN ABOUT PHP
break
break(1) User Commands break(1)NAME
break, continue - shell built-in functions to escape from or advance within a controlling while, for, foreach, or until loop
SYNOPSIS
sh
break [n]
continue [n]
csh
break
continue
ksh
*break [n]
*continue [n]
DESCRIPTION
sh
The break utility exits from the enclosing for or while loop, if any. If n is specified, break n levels.
The continue utility resumes the next iteration of the enclosing for or while loop. If n is specified, resume at the n-th enclosing loop.
csh
The break utility resumes execution after the end of the nearest enclosing foreach or while loop. The remaining commands on the current
line are executed. This allows multilevel breaks to be written as a list of break commands, all on one line.
The continue utility continues execution of the next iteration of the nearest enclosing while or foreach loop.
ksh
The break utility exits from the enclosed for, while, until, or select loop, if any. If n is specified, then break n levels. If n is
greater than the number of enclosing loops, the outermost enclosing loop shall be exited.
The continue utility resumes the next iteration of the enclosed for, while, until, or select loop. If n is specified then resume at the n-
th enclosed loop. If n is greater than the number of enclosing loops, the outermost enclosing loop shall be used.
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 that follow 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 also that word splitting and file name genera-
tion are not performed.
