Okay, it makes a lot more sense what you are trying to do now. There
are several much better ways (IMHO) to do this.
Firstly, if you use /bin/time instead of the shell builtin 'time'
command, you can specify both a format and an output file:
/bin/time -f "%e seconds elapsed" -o /tmp/timelog \
sftp firstname.lastname@example.org < fileWithActions
What you're doing now ends up calling perl three times. If you're going
to use perl you might as well just call perl once and do everything
there, since it is far more powerful than screwing around with
head/tail/expr/etc (which are very inefficient ways to process text
since you fork/exec a process for each operation):
perl -e 'use Time::HiRes qw(time); $start = time;
system("sftp email@example.com < fileWithActions");
printf "%.2f seconds elapsed\n", time - $start;'
This allows for any kind of formatting of the output you desire, as well
as better-than-second granularity.
