Full Discussion: Redirection of output to a log file
Top Forums UNIX for Dummies Questions & Answers Redirection of output to a log file Post 302227400 by otheus on Thursday 21st of August 2008 06:31:57 AM

Right... at is a batch program which will queue the process and run it at a future point in time. Redirecting NOW doesn't redirect the output later. (Redirection is a shell function). "at", however, will save the program's output to a file and email it to you. So check in Mail (or make sure email is properly setup for forwarding.) If you don't want email, then do this at the beginning of the script:

Code:
# ... initialization of your script
exec >$HOME/script-output.$$ 2>&1
# rest of your script

If you want to append to the same file everytime, do this instead:

Code:
# ... initialization of your script
exec >>$HOME/script-output.log 2>&1
# rest of your script

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.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

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.
