RE: {bb} Timing a script

[Ralf.Strandell@silja.com]

Hi,

There's also a nice command called "time".

The following compound command runs script.sh with time
and then forwards the output to awk for further processing.
The parentheses and 2>&1 redirection are important.

  TIME=`( time script.sh ) 2>&1 | awk ' $1 == "real" { print $2 } '`

Awk then picks the "real" time line from the output of "time script.sh".
You'll get a result like this: TIME=0m0.01s

You are probably only interested in minutes. Hence:

  TIME=`( time script.sh ) 2>&1 | awk ' $1 == "real" { print $2 } ' | sed
's/m.*//g'`

Next you'll want to set the color:

  test "$TIME" -gt "$YELLOW_LEVEL" && COLOR=yellow
  test "$TIME" -gt "$RED_LEVEL" && COLOR=red

You might wonder why I quoted numeric variables.
Reason: In case (when) something unexpected happens and TIME is left empty,
there will be a red warning instead of an error message that could go
undetected:
$ test "" -gt 0
$ echo  $?
1
$ test -gt 0
/bin/ksh: test: argument expected
