res=`echo $line | grep [prefix_identifier.]property_name[.suffix_identifier]`
if [ $res ]; then
ExpValue=`echo $res | cut -d "=" -f2`
For example, to read the custom env.path.jar prerequisite property and check
whether the JRE is set in the PATH variable:
res=`echo $line | grep env.path.jar`
if [ $res ]; then
ExpValue=`echo $res | cut -d "=" -f2`
In the example:
echo "\`wrlTrace "Starting" "env.path.jar"\`" >>/tmp/prs.check
echo "\`wrlTrace "Executing" "env.path.jar"\`" >>/tmp/prs.check
echo "\`wrlDebug "Starting" "env.path.jar"\`" >>/tmp/prs.check
echo "\`wrlDebug "Expected" "ExpValue" \`" >>/tmp/prs.check
collector.
echo "\`wrlTrace "Starting" "[prefix_identifier.]property_name
[.suffix_identifier]"\`" >>/tmp/prs.check
echo "\`wrlTrace "Executing" "[prefix_identifier.]property_name
[.suffix_identifier]"\`" >>/tmp/prs.check
echo "\`wrlDebug "Starting" "[prefix_identifier.]property_name
[.suffix_identifier]"\`" >>/tmp/prs.check
echo "\`wrlDebug "Expected" "ExpValue" \`" >>/tmp/prs.check
Note: If the custom collector has subtypes, that is, [suffix_identifier] in the file
name and needs additional checks based on subtype, pass the
[differentiator_suffix_identifier] differentiator for the subtype to the custom
collector.
echo "ss=\`./[prefix_identifier.]property_name[.suffix_identifier]
[differentiator_suffix_identifier]\`" >>/tmp/prs.check
In the example:
echo "ss=\`./env.path.jar\`" >>/tmp/prs.check
Note: Examples of differentiators for the script_name subtype for the
os.file.script_name prerequisite properties are the paths to the scripts that are
passed to the os.filepath collector:
echo "ss=\`./os.filepath /usr/bin/expect\`" >>/tmp/prs.check #os.file.expect
echo "ss=\`./os.filepath /usr/bin/tar\`" >>/tmp/prs.check #os.file.tar
echo "ss=\`./os.filepath /usr/bin/gzip\`" >>/tmp/prs.check #os.file.gzip
collector.
echo "\`wrlTrace "Finished" "[prefix_identifier.]property_name
[.suffix_identifier]"\`" >/tmp/prs.check
echo "echo \"[prefix_identifier.]property_name
[.suffix_identifier]=\$ss\"" >>/tmp/prs.check
echo "\`wrlDebug "Finished" "[prefix_identifier.]property_name
[.suffix_identifier]"\`" >>/tmp/prs.check
echo "\`wrlDebug "OutPutValueIs" \$ss\`" >/tmp/prs.check
echo "\`wrlTrace "Done" "[prefix_identifier.]property_name
[.suffix_identifier]"\`" >>/tmp/prs.check
fi
In the example:
echo "ss=\`./env.path.jar\`" >>/tmp/prs.check
echo "\`wrlTrace "Finished" "env.path.jar"\`" >>/tmp/prs.check
echo "echo \"env.path.jar=\$ss\"" >>/tmp/prs.check
