Re: [IBMiOSS] QIBM_QSH_CMD_ESCAPE_MSG

[Craig Richards <craig@xxxxxxxxxxxxxxxx>]

Just an addendum to this...

Both approaches ( using "set -e" or separating the command with && )
provide the functionality I requested above.

However I noticed that the "set -e" option appears to prevent the error
text from being written to STDOUT.

So I'm using && because I'm keeping the STDOUT contents in a logfile in the
event of an error.
