Capture Shell Script Output To A File
Hi,
I am running a shell script called dbProcess.sh which performs shutdown and startup of various Oracle instances we have.At the time of execution the script produces the following output to the command line window
$./dbProcess.sh stop
#### Run Details ######
Hostname : server-hop-1

I would like to create an output file being at the time of executing the dbProcess.sh and the process must write all the output lines of the dbProcess.sh to this file.
I would like to clarify that i am not looking for any kind of redirection commands using the > or >> symbol.
What i am looking out for is a series of commands that i will be able to add to my dbProcess.sh shell script which will start a log file write all the shell output to the logfile and at the end of it save and exit the log file. I dont mind if the output is not showing up on the stdout for me most important aspect is the creation of this logfile and to write all output to this logfile.
I tried the to add lines to dbProcess.sh using the unix script command.But it did not work because when the shell script executed the script command line it stopped and waited for me to type exit for it to continue.
Please let me know if you have any clarification.
Thanks and kind Regards,
Rajan.S

Hi
I have a script that will run multiple unix & sql commands. I want to see the output as well as capture it to a log file for further analysis. Is there an easy way to do that instead of adding "tee -a logfile" on everyline or even on the execute line (i.e. script | tee -s logfile).

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.
