[Bash] Script to compile and run simple Java Programs

[chlortho]

Not sure if this belongs in Java or Scripting...

Anyhow, I am trying to write a script to compile and run simple java programs. Creating a batch file in DOS is a piece of cake:

Code: [Select]

javac %1.java
java %1
However, in BASH it's a bit more complicated (at least I think it is). Here is what I have so far, I feel like it's close. My issue (I think) is that there is not a -o switch with javac to specify the output file name. is there another way?

Code: [Select]


#!/bin/bash
# Script to compile and execute a jave program
 
# Get file name without the .java extension
file_name=$(echo $1|sed 's/\(.*\)\.java/\1/')
 
# Compile the program with -o option to specify the name of the binary
javac -o $file_name.out $1
 
# If there were no compilation errors, run the program
if [[ $? -eq 0 ]]; then
        ./$file_name.out
fi

1. this is obviously not python, but a shellscript.
2. get that ugly ass font from my screen.
3. haven't tested it, but it looks useful (kinda).

1. right. I'm retarded. I was working on a python script to configure my network manager for my university wifi. Must have been thinking about two things at the same time.
2. Yeah. It looks like Courier...  I cut and pasted from vim...  so not really sure.
3. You're right, it's 'kinda' useful - more of just to see if I could.


Excellent feedback, though. Thanks.

I don't think so? Should be as simple as:

Code: [Select]

javac $1.java
java $1


Holy crap...  That was it....  syntax %=CMD and $=Unix    wow.... thanks!  talk about over complicating things....haha
