Does anyone know how I can do this?

I'm trying to write a script that will look in an /exports folder for the oldest export file and move it to a /staging folder. "Oldest" in this case is actually determined by date information embedded in the file names themselves.
Also, the script should only move a file from /exports to... (6 Replies)
Hi,
I have two files, one of which I would like to sort based on the order of the data in the second. I would like to do this using a simple unix statement.
My two files as follows:
File 1:
12345 1 2 2 2 0 0
12349 0 0 2 2 1 2
12350 1 2 1 2 2 2

Hi Guys,
My client (dear clients, I hate to love you) has the funky idea of sorting a 5G flat file.
Certainly enough, this is taking forever and also fulls the / of our machine.
Any idea of how we could proceed to make this a little bit more efficient?
Maybe by forcing sort to "stay in... (7 Replies)

trace_printk
TRACE_PRINTK(9) Driver Basics TRACE_PRINTK(9)NAME
trace_printk - printf formatting in the ftrace buffer
SYNOPSIS
trace_printk(fmt, ...);
ARGUMENTS
fmt
the printf format for printing
...
variable arguments
NOTE
__trace_printk is an internal function for trace_printk and the ip is passed in via the trace_printk macro.
This function allows a kernel developer to debug fast path sections that printk is not appropriate for. By scattering in various printk
like tracing in the code, a developer can quickly see where problems are occurring.
This is intended as a debugging tool for the developer only. Please refrain from leaving trace_printks scattered around in your code.
(Extra memory is used for special buffers that are allocated when trace_printk is used)
A little optization trick is done here. If there's only one argument, there's no need to scan the string for printf formats. The trace_puts
will suffice. But how can we take advantage of using trace_puts when trace_printk has only one argument? By stringifying the args and
checking the size we can tell whether or not there are args. __stringify((__VA_ARGS__)) will turn into "() " with a size of 3 when there
are no args, anything else will be bigger. All we need to do is define a string to this, and then take its size and compare to 3. If it's
bigger, use do_trace_printk otherwise, optimize it to trace_puts. Then just let gcc optimize the rest.
