If you feel writing the same command over and over again in Bash, which is Console environment where you write clear && javac TreeStory.java && java TreeStory
, you have two options:
- create script
run.sh
and save it in workspaces
In order to do that create file run.sh
(it can have any name actually and not sh
neccessarily), and put into it the line, that you execute:
clear && javac TreeStory.java && java TreeStory
The type in console
chmod +x run.sh
After that you can type the following
./run.sh
And your script will execute commands in script
Try that out and let me know i that worked
Second option will be to create alias
. But this one you will have to re-create every time you run workspaces...
If you want to know more about aliasing and console commands, take a nice course here at Treehouse

Make sure you also use auto-completion.
When you start typing anything, like
javac Tree
, try to hit "Tab" button, it should auto-completeTree
toTreeStory.java
. In this case Bash is configured to look for file in the current directory.The same works for commands. If you type
java
and hitTab
twice, console will show you possible programs that Bash knows, and that are installed. Try that out as well.Also if you are interested, here is how
alias
worksType in console
alias rj="clear && javac TreeStory.java && java TreeStory"
Then you can type
rj
in console, and that will execute the same command, but without this./
There are benefits for using both approaches. Of course with
Java
it is better to learn IDE :) with 'Local Development Environments Course', because it does all the hard work for you, but still knowing Bash commands can be very helpful.http://www.tldp.org/LDP/abs/html/aliases.html
