return value from java and assign it to a variable in shell script

[Chandrasekaran SanthanaKrishnan]

I have a requirement where I am running a script and invoking a java program which will return a string (filename).

This returned value must be assigned to a local variable using which i have to find diff between two files.


saving output in a local file and then cat the file and assign it to variable is also not working.

java myclass param1 param2 > localFile.txt

fileName='cat localFile.txt'

below mentioned method is also not working:

out='java MyClass Param1 param2'

out=$(java MyClass Param1 param2')

please give a solution


ps: I am running the shell script on solaris OS.

I tried out an example. You could try it in bash.

#!/bin/bash
var1=`java Test`
echo $var1

#seems to work for me.

Try and let me know.

Backticks are deprecated. Instead use $(...). You can nest it easily, and it is better readably.
#!/bin/bash var1=$(java Test) echo $var1
