Hello All,
I have some unique requirement.
I have written a very lengthy script which calls number of resource script to execute a particular task.
What I want is output of each command(called from main script and resource scripts) should go to a particular file and I should be able to access that file within my main script (Just want to attach it to mail.). Only output of "echo" command should appear on console.
Is there any way to do this ? I thought of

Code:
"Script"

command but it prints output to console as well.
Another way is to redirect output of each command to file but I have more than 2000 commands in total so that looks tough and something that I want to avoid.
Thank you very much.

Regards,
Anand Shah

Hello,

ok I think we have to keep some few things in mind here like file should STOP updating before sending to it mail as attachment, we can put a sleep process for 1 or 2 mins after your script completion. Then we can fetch the file and snd it to mail as an attachment.

For scripts which you want to execute in Bacground or you don't want their output to be shown at screen please use nohup command for same.

Thanks,
R. Singh

NAME

       script - make record of a terminal session

SYNOPSIS

       script [-a] [filename]

DESCRIPTION

       The  script  utility  makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the
       record is saved in the file typescript. See WARNINGS.

       The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends
       when the forked shell exits or when Control-d is typed.

OPTIONS

       The following option is supported:

       -a	Appends the session record to filename, rather than overwriting it.

NOTES

       script places everything that appears on the screen in filename, including prompts.

WARNINGS

       script  can  pose  a  security risk when used in directories that are writable by other users (for example, /tmp), especially when run by a
       privileged user, that is, root. Be sure that typescript is not a link before running script.
