Issue/Introduction

Supplemental documentation for using RUN HOST COMMAND conditions on Unix.
 

Environment

OS: Unix

Resolution

The following information for Unix is meant to supplement the 'Selecting Condition Actions' --> 'Run HOST COMMAND' section of the Applications Manager documentation that can be found here:

https://docs.automic.com/documentation/webhelp/english/ALL/components/AM/latest/All%20Guides/help_en.htm#AM_Development_Guide/Selecting_Condition_Actions.htm%3FTocPath%3DDevelopment%2520Guide%7CWorking%2520with%2520Conditions%7CSelecting%2520Condition%2520Values%7C_____4

Within the action argument of the Run Host Command condition, Unix operating system commands can be chained together, separating commands using a semicolon (;). 
 

Example: echo “Header line” > outfile1; echo “Detail line” >> outfile1 

 
Prior to passing the command(s) specified within the action argument of the RUN HOST COMMAND condition to the host for execution, the following evaluations will occur: 

• Dollar sign ($) characters will be removed unless the dollar sign is preceded by the tilde (~) character. 

Example: $test would evaluate to test 

Example: ~$test would evaluate to $test 

 

• Pairs of percent sign (%) characters will be removed, starting from the left.

Example: date +%m%d would evaluate to date +md

Example: date +%m%d%y would evaluate to date +md%y 

Example: date +%Y would remain unchanged 

 

• Curly braces { } will be removed and the contents between the curly braces will be evaluated as follows: 

Example: {#xxx} – evaluates to the value associated with the specified Application Manager Substitution variable.  

If #xxx substitution variable exists with the value of “xxx_subvar_value”, then {#xxx} would evaluate to xxx_subvar_value 
If #xxx substitution variable does NOT exist, then {#xxx} would evaluate to #xxx 

Example:  {xxx} – evaluates to the value associated with specified Application Manager Replacement Value. 

If xxx replacement value exists with the value of “xxx_replacement_value”, then {xxx} would evaluate to xxx_replacement_value 

If xxx replacement value does NOT exist, then {xxx} would evaluate to xxx
