bashrc doesn't identify the java home

Question

I had installed java in ubuntu but when I set the java home in ~/.bashrc the command doesn't work I had used these commands in ~/.bashrc using this command

sudo gedit ~/.bashrc

# JAVA HOME directory setup

export JAVA_HOME =usr/lib/java/jdk1.8.0_111
set PATH = $PATH:$JAVA_HOME/bin
export PATH

after that every time I open a terminal this message shows to me

bash: export: `=usr/lib/java/jdk1.8.0_111': not a valid identifier

Answer 1

You should assign variables with no spaces. And it is better to quote strings in bash.

export JAVA_HOME="usr/lib/java/jdk1.8.0_111"
export PATH="$PATH:$JAVA_HOME/bin"

Answer 2

Do not use spaces in the variable assignment.

sudo gedit ~/.bashrc

# JAVA HOME directory setup

export JAVA_HOME=usr/lib/java/jdk1.8.0_111
export PATH=$PATH:$JAVA_HOME/bin

Answer 3

Avoid the spaces between variable assignments and recommend double-quoting the values assigned to avoid word-splitting done by shell.

export JAVA_HOME="usr/lib/java/jdk1.8.0_111"
export PATH="$PATH:$JAVA_HOME/bin"

Do re-check your JAVA_HOME path, if it should start with a / , since you were missing it as part of the question. The below might have been your actual path.

export JAVA_HOME="/usr/lib/java/jdk1.8.0_111"
