Hello,
I am running a bash script under linux which first defines an CA-array like
j=0

num2=10.00
until
do
CA='echo $num1 + $j*$num2'
j=$
done
within the later awk section of this same script I want to read data from a file. If the value of the second column is... (3 Replies)

So, I've been playing with speeding up some analysis we do by using multiple threads of awk (actually, mawk, but code-compatible as far as I use it) on multiple CPU cores. So, I have a big data file and I have several copies of exactly the same processor script, written in mawk. I also have a... (8 Replies)

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]
ksh93
+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 manual 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
variable assignment. This means that tilde substitution is performed after the = sign, and also that word splitting and file
name generation are not performed.
ksh93
break is a shell special built-in that exits the smallest enclosing for, select, while, or until loop. It also exits the nth enclosing loop
if n is specified. Execution continues at the command following the loop or loops.
If n is specified, it must be a positive integer >=1. If n is larger than the number of enclosing loops, the last enclosing loop is exited.
continue is a shell special built-in that continues execution at the top of the smallest enclosing for, select, while, or until loop, if
any; or of the top of the nth enclosing loop if n is specified.
If n is specified, it must be a positive integer >=1. If n is larger than the number of enclosing loops, the last enclosing loop is used.
On this manual page, ksh93(1) commands that are preceded by one or two + symbols are special built-in commands and are treated the follow-
ing 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. Built-in commands are not valid function names.
5. Words following a command preceded by ++ that are in the format of a variable assignment are expanded with rules as a variable
assignment. This means that tilde substitution is performed after the = sign and field splitting and file name generation are
not performed.
