Hello guys!

Hello,
I have some bitrate data in a csv which is in an odd format and is difficult to process in Excel when I have thousands of rows. Therefore, I was thinking of doing this in bash and using awk as the primary application except that due to its complication, I'm a little stuck.

I have a ksh93 script I use that processes a file list in the order that they exist in the list. I would like to speed up processing of the list by having multiple processes handle it at once. I was thinking that perhaps a good way to handle this would be to write the list to a named pipe and some... (4 Replies)

for
for(n) Tcl Built-In Commands for(n)
__________________________________________________________________________________________________________________________________________________NAME
for - ``For'' loop
SYNOPSIS
for start test next body
_________________________________________________________________DESCRIPTION
For is a looping command, similar in structure to the C for statement. The start, next, and body arguments must be Tcl command strings,
and test is an expression string. The for command first invokes the Tcl interpreter to execute start. Then it repeatedly evaluates test
as an expression; if the result is non-zero it invokes the Tcl interpreter on body, then invokes the Tcl interpreter on next, then repeats
the loop. The command terminates when test evaluates to 0. If a continue command is invoked within body then any remaining commands in
the current execution of body are skipped; processing continues by invoking the Tcl interpreter on next, then evaluating test, and so on.
If a break command is invoked within body or next, then the for command will return immediately. The operation of break and continue are
similar to the corresponding statements in C. For returns an empty string.
Note: test should almost always be enclosed in braces. If not, variable substitutions will be made before the for command starts execut-
ing, which means that variable changes made by the loop body will not be considered in the expression. This is likely to result in an
infinite loop. If test is enclosed in braces, variable substitutions are delayed until the expression is evaluated (before each loop iter-
ation), so changes in the variables will be visible. For an example, try the following script with and without the braces around $x<10:
for {set x 0} {$x<10} {incr x} {
puts "x is $x"
}
