My AWK script will change $2 and $3 based on the value of $1.
The values in $1 are distinct and must match to one of the values in the first column with every call to this script.
So far it works fine.
What I'm wondering how to do is to test if the AWK code successfully completed.
If I call $? I always get a status of 0 (since the cat does work fine).
How do I verify that the AWK code did not error out?
Hi. I have a kornshell script that runs on a daily basis as a cron job. Part of what the script does is copy the folder contents from another server to the current server (server where KSH script is running).
I have a scp command, as follows:
scp $REMOTE_HOST:$REMOTE_FILE_DIR/* $TMP_DIR

service(8) System Manager's Manual service(8)NAME
service - run a System V init script
SYNOPSIS
service SCRIPT COMMAND [OPTIONS]
service --status-all
service --help | -h | --version
DESCRIPTION
service runs a System V init script in as predictable environment as possible, removing most environment variables and with current working
directory set to /.
The SCRIPT parameter specifies a System V init script, located in /etc/init.d/SCRIPT. The supported values of COMMAND depend on the
invoked script, service passes COMMAND and OPTIONS it to the init script unmodified. All scripts should support at least the start and
stop commands. As a special case, if COMMAND is --full-restart, the script is run twice, first with the stop command, then with the start
command.
service --status-all runs all init scripts, in alphabetical order, with the status command.
If the init script file does not exist, the script tries to use legacy actions. If there is no suitable legacy action found and COMMAND is
one of actions specified in LSB Core Specification, input is redirected to the systemctl. Otherwise the command fails with return code 2.
FILES
/etc/init.d
The directory containing System V init scripts.
ENVIRONMENT
LANG, TERM
The only environment variables passed to the init scripts.
