Need a scripting help

Hi all

MY shell script is creating one file which contain many OS level
command.
I am then executing that script.
I want to know the time taken by each command.
For that purpose i want to add date command after each line in the
that file like:

....
OS Command 1
date
OS Command 2
date
....

Can someone tell me how to add date command after each line in that
file?
It would be of great help for me.

Use the toolbox, if sample file is:
$ cat /tmp/_lines
one
two
three
many

then, with awk:
$ awk '{print ; print "date"}ate/' /tmp/_lines
one
date
two
date
three
date
many
date
last
date

or, with sed:

$ sed 's/$/\ndate/' /tmp/_lines
one
date
two
date
three
date
many
date
last

unprotected shell:
$ while read ll; do printf ${ll}"\ndate\n" ; done < /tmp/_lines
one
date
two
date
three
date
many
date

here's a possible protected version:
( IFS="" ; while read ll; do printf ${ll}"\ndate\n" ; done < /tmp/_lines )

of course the bizarre "}ate" was a glitch in my X cut and paste :-)

$ awk '{print ; print "date"}/' /tmp/_lines

sed 'a\
date'

Or, at the beginning of your script, add
trap date DEBUG
and change the interpreter to bash, zsh or ksh93.
