Supports the standard [ serialization options ]
Description
xproperties can be used to create new properties files, transform files from text to xml form, add, delete and print property values.xproperties creates a Java Properties object in memory, then optionaly loads values from a file (in text or xml form), optional adds or updates the properties then prints the resultant properties file in either text or xml form.
The text and XML forms are as specified (and implemented) by the Java java.util.Properties object
if one or more -v (or -var) options are specified then instead of serializeing the entire resultant properties file then one or more values from the (possibly edited) properties file are output followed by a newline.
If a input file is specified as "-" then stdin is used.
If neither -v, -text or -xml is specified then -xml is presumed.
Examples
Create a new properties file in text form with initial contents
xproperties -text -a var1="Value 1" -add var2="Value 2"
Produces this output
#Sat Nov 14 12:42:24 EST 2009 var2=Value 2 var1=Value 1
Convert the above property file to xml form
xproperties -in file.properties
Produces
<!DOCTYPE properties SYSTEM "http://java.sun.com/dtd/properties.dtd" []>
<properties version="1.0">
<entry key="var2">Value 2</entry>
<entry key="var1">Value 1</entry>
</properties>
<properties version="1.0">
<entry key="var2">Value 2</entry>
<entry key="var1">Value 1</entry>
</properties>
Print out the value of var2 from the above xml format
xproperties -inxml prop.xml -v var2
Produces
Value 2
Using with tie
xproperties output can be easily referenced using the tie command
Example
Input file config.properties a text formated properties file
login=admin
This command
PROPS=$<(xproperties -in config.properties)
tie PROPS './/entry[@key = $_ ]/string()'
echo ${PROPS:login}Produces
admin
Return Value
Returns 0 if the command executed successfully, 1 if there was an error.Commands
