Operating Systems Linux Ubuntu Check for download before running command Post 303032829 by Don Cragun on Sunday 24th of March 2019 09:52:13 PM

The code in your script:
Code:
        echo "Now exiting."
        sleep 2 
        break

implies that you believe that writing the string Now exiting. to standard output from your script causes the script to stop running. It does not do that. It simply writes that text and continues running the rest of the code in your script. In this case, it sleeps for two seconds and breaks out of the loop looking for files being downloaded. And, then it immediately starts testing for the conditions you have set up to be verified as being present before you suspend your computer. If you want your script to exit (as indicated by your echo statement), you need to actually include an exit statement in your code!

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: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWcsu | +-----------------------------+-----------------------------+ |CSI |Enabled | +-----------------------------+-----------------------------+ SEE ALSO
