How to capture output of unix time command?

3 New Member
I want to execute a unix time command using perl, and capture the output (specifically, the time it takes the command to execute).

i tried using the system command:
system("time command ");
however, when i try to capture the output, the capture output does not contain the amount of time it took to execute

when i try to do:
$var = `time command `;
there is the same problem (the ouput from the command is saved in the variable; however, the time is not)

So, how do i capture the time it takes a unix command to execute?

On Solaris 10 (using bash shell), I had trouble getting `time -p <command> 2>&1` to work. I solved it by executing the time command in its own shell as follows:

TIMING=`bash -c "time ls -l" 2>&1`

I'm calling a command from within a python script and I need to be able to both catch the output (stdout and stderr) from it and also have the PID (so that I can kill it) I can do one or other of these, but I can't find any way to do them both at the same time. So far, I've got the following options:

Not sure what I should do here. I know that DOS/CMD can capture the output of EXE files in Win32. I know that os.popen() has been recommended for this, but the couple of times I've tried, it didn't seem to work well. I haven't had a lot of need to do this recently, but we're trying to automate some processes right now that require us to trap the output of a command line and react accordingly. Any suggestions on the best method for...

I have Red Hat Enterprise Linux 4. I was just reading up about UTC and leap seconds. Is it true on my system that the Unix time may skip up or down by one second at midnight when there is a leap second? By "Unix time" I mean the integer returned by time() and similar functions. I'm concerned about the "down" case. Some of the software I've written

I am running a system command and I need to capture the output so that, if the command has done what it is meant to, the program does something different. If I do this: int i; i=system("cd C:\\Dave\\C-programming\\Password Cracker\\ & ftp -s:ftpscript.txt ftp.collateraldesign.co.uk"); printf ("The value returned was: %d.\n",i); The value returned is 0.

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not.
