Add a > <filename> at the end:

Quote:

$time scp local_file remote_file > filename.txt

$time scp local_file remote_file >filename 2>&1

This puts both stdout and stderr in the file. I use this frequently.

Opps; slow on the response and CRC123 got ahead of me. That happens frequently. Anyone have a good way to check the list before posting a reponse BEFORE making a fool out of oneself? I'll try cutting my response, reloading the thread (checking for other responses), and pasting my response back if it is still relavent. Dave

Sorry dave. I sometimes use the "Preview Post" button and I think it shows the most recent post's up to the point when you click.

Sounds like you got the output from the scp command instead of the time. Did you include time in front of the scp command?

Yes , I use time scp localfile remotefile >test_speed 2>&1

but found that the file test_speed is empty .

thx

Ok, apparently bash is executing its built in time command. Try explicitly calling the gnu version:

Code:

/usr/bin/time scp localfile remotefile >test_speed 2>&1

If you want output of scp and output of time in seperate files:

Code:

/usr/bin/time scp localfile remotefile > test_speed 2> time.txt
or
/usr/bin/time -o time.txt scp localfile remotefile >test_speed

There's a way to specify output of time command too with -f option. read the man page.

EDIT: I mean 'specify format of time command' in above line

OK, try this: time (scp localfile remotefile) >test_speed 2>&1
I think that will run your command in a sub-shell and do what you want.

thx reply,

the below works , it is good.

/usr/bin/time -o time.txt scp localfile remotefile >test_speed

but if I want the output only have the time elapsed ( now there are too many information ) , can advise what can i do ? thx

Code:

/usr/bin/time -f "%e" -o time.txt scp localfile remotefile >test_speed

Look in manual page of time for more formatting options. If you don't have that man page installed, "man time" in google will do
