hdparm + HDIO_DRIVE_CMD(null) (wait for flush complete) failed: Inappropriate ioctl
Hi All,
Am finding performance of my SD card using hdparm.
Am not aware of "HDIO_DRIVE_CMD(null) (wait for flush complete) failed: Inappropriate ioctl for device". What actually makes it to occur?? What does this problem mean? How to resolve it??
I'm using PERL on windows NT to try to run an extract of data. I have multiple zip files in multiple locations. I am extracting "*.t" from zip files and subsequently adding that file to one zip file so when the script is complete I should have one zip file with a whole bunch of ".t" files in it.

When running a command using the >(cmd) syntax in bash how do you wait for the command to complete before moving on in your script?
Here is a simple example:

Let's say I start process A.sh, then start process B.sh. I call both of them in my C.sh
How can I make sure that B starts its execution only after A.sh finishes.
I have to do this in loop.Execution time of A.sh may vary everytime.
It is a parameterized script. (17 Replies)

ioctl
IOCTL(2) BSD System Calls Manual IOCTL(2)NAME
ioctl -- control device
SYNOPSIS
#include <sys/ioctl.h>
int
ioctl(int d, unsigned long request, char *argp);
DESCRIPTION
The ioctl() function manipulates the underlying device parameters of special files. In particular, many operating characteristics of charac-
ter special files (e.g. terminals) may be controlled with ioctl() requests. The argument d must be an open file descriptor.
An ioctl request has encoded in it whether the argument is an ``in'' parameter or ``out'' parameter, and the size of the argument argp in
bytes. Macros and defines used in specifying an ioctl request are located in the file <sys/ioctl.h>.
RETURN VALUES
If an error has occurred, a value of -1 is returned and errno is set to indicate the error.
ERRORS
Ioctl() will fail if:
[EBADF] d is not a valid descriptor.
[ENOTTY] d is not associated with a character special device.
[ENOTTY] The specified request does not apply to the kind of object that the descriptor d references.
[EINVAL] Request or argp is not valid.

An ioctl() function call appeared in Version 7 AT&T UNIX.
