Can anyone tell me what all the fields that the csh time command prints out
are? When I do something like 'time ls' in csh, I get:
1.3u 0.7s 0:11 19% 23+79k 3+0io 2pf+0w
The man page for csh documents the fist 4 fields as user time, system time,
elapsed time (all in seconds), and utilization (i.e. (u+s)/e). I guess
that the next fields are memory usage, io calls, and page faults. What the
numbers mean is not described. Could anyone send me a definite description
of the last 6 numbers?
Thanks,
Israel

The numbers are measured in 512-byte pages. 3+0io -- This is the I/O charged to the process (not necessarily initiated by the process). The 3 is the total number of requests, the 0 is the number of disk accesses. The difference is the number of buffer cache hits. 2pf+0w -- The 2pf is the number of page faults that required disk I/O to read the page (known in unix as major faults). The 0w is the number of times ths process was swapped to disk. -jeff-

Note that these statistics are machine dependent. The precise
meaning depends on the hardware and how the kernel counts things.
On anything other than a vax, check very carefully before you
assume that they mean what they do on a vax.jerryp@tektools.UUCP (10/21/86)

The man page was actually written by Mark Wittenberg ({zehntel,varian}!rtech!mark). Among the neat, undocumented stuff in it was the fact that you can change the output format of the "time" command by setting a shell variable named "time". For instance, here's a setting I like to use: set time=(0 "user=%U sec, system=%S sec, elapsed=%E min, cpu use=%P, %W swaps,\ %I disk reads, %O disk writes. Data+stack+text pages: %K avg., %M max.") The man page was written for 4.1bsd csh; I don't know if it much has changed for 4.[23]bsd. If anyone wants a copy of the man page, let me know. If I get enough requests, I'll post it to net.sources. --Jerry Peek, Tektronix, Inc. US Mail: MS 74-900, P.O.
