Sarah S updated KNOX-1833:
--------------------------
Affects Version/s: 1.3.0
1.2.0
Description:
{{APP_BIN_DIR="$( cd "$( dirname "$\{BASH_SOURCE[0]}" )" && pwd )"}}
When the script is running in Korn shell, $\{BASH_SOURCE[0]} is always empty
and this is because $\{BASH_SOURCE[0]} is valid only for Bash shell. Thus, the
path is not constructed correctly. Later on when we have any other installation
scripts running, it is unable to find gateway.sh since the Bash Source is not
inclusive of Korn shell path to the gateway.sh.
However we did find a work around for it. A simple script has to be added into
the gateway.sh script. It basically checks for two kinds of shells: either Bash
or Korn and then adds the path according to whatever the type is. Here's what
the code snippet looks like:
{code:java}
if [ $SHELL == '/bin/bash' ] || [ $SHELL == '/bin/sh' ]
then
THIS_SCRIPT=${BASH_SOURCE[0]}
echo $THIS_SCRIPT
elif [ $SHELL == '/bin/ksh' ]
then
THIS_SCRIPT=${.sh.file}
echo $THIS_SCRIPT
else echo NO MATCH.
fi
APP_BIN_DIR="$( cd "$( dirname ${THIS_SCRIPT} )" && pwd )"
{code}
