Is it possible to get the number of javac's errors?

Question

I would want to write a Bash script which executes some operations after a javac, depending on the presence or not of compilation errors.

In fact, if there is at least one error, these operations will not be executed. Otherwise, they will.

I tried to do something like that but it didn't work :

javac_return=`javac [...] -d ../class`
if [ javac_return -eq 0 ]
then
# operations
fi

Answer 1

for the value of a bash variable you have to use $. however, the status code is not returned as the output.

you can do, however

if javac [...] -d ../class;
then
# next command
else
# error handling
fi

or, with the command chaining idiom

command && next_command_if_succeeded || or_if_failed
