I want to have a step that executes the Command commands if the agent is on unix and the Else Command part if the agent is running on windows. I tried to put this condition but it didn't work:

true(BF_AGENT_PLATFORM==aix 3 5)

true(BF_AGENT_PLATFORM=="aix 3 5")

Any idea how can I build the conditional expression properly?


Thanks!

Hi epzee,

I use the following condition frequently in my libraries.

${BF_AGENT_PLATFORM} contains Windows

If you don't like using the 'contains', then I would suggest using the comparison operator of 'eq' instead of '==' since you're comparing a string instead of number.

Great, that's exactly what I was looking for! Is there any doc with a list of all possible operators? I only found the string operators in the online help, but no example of the contains condition you wrote.

Thanks!

Hi,

In the documentation at 'Working with steps' -> 'Controlling execution flow' -> 'Condition functions', there are some examples of the various functions that can be used in the condition field.

It's also possible to have a CMD script and a Bourne-like shell script
in the same file. It depends on the fact that "goto" is a command in
CMD but not in a Bourne-like shell. So when the script is run by CMD,
the goto executes; when run by bash or sh or the like, it falls thru
to the next statement (with an error exit code and an error message on
stderr, file descriptor 2).

On my system, where the UNIXy shell is Cygwin's bash running on
Windows:

GOTO :CMD_COMMANDS 2>NUL:
# The next is a Cygwin extension to cause the shell to
# ignore the carriage returns.
set -o igncr # must keep a comment here.

# bash commands here.
exit

:CMD_COMMANDS

REM CMD commands here
exit

For your setup, where the agent is on real Linux or UNIX, you'd remove
the "set -o igncr" and instead "rm NUL:".

Carriage returns appear to be an artifact of the Opera Web browser
only. When I run Opera on Windows and save a step, it appears to send
in the text with lines ending in carriage return-linefeed. From
Firefox or IE (!), the lines in a step only end in newline.

It's bad when that happens for the .drill command, because it refuses
to ignore the trailing carriage return and throws a syntax error and
usage message, and there's no workaround other than switching
browsers. (RBF supports only IE and Firefox.)
