Using trap

[Chandrahasa s]

Hi Gurus,

I am using trap for updating history file with time stamp,

trap 'date "+# %c" | read -s' debug

Here this will update time stamp,
i want to get "who am i" out also histfile.
Kindly help to format trap syntax for this.

Hi Chandra:

Try this:

# trap 'print -s $(who am i; date)' DEBUG

Hi (again):

And you would probably want:

# trap 'print -s $(date "+# %c"; who am i)' DEBUG

Regards!
