A bash script that allows you to execute Haskell files more easily.

haskell

#!/bin/bash

# A script that automatically compiles and runs Haskell files

# First paramter is the Haskell file

# Temporary file location
temp=~/../../tmp

# Compile Haskell file
ghc -o $temp/Main -outputdir $temp $1

# Run the file
$temp/Main

# Cleanup
if [ $? -eq 0 ]; then
    rm $temp/Main.hi
    rm $temp/Main.o
    rm $temp/Main

Move this file to your /bin/ directory by calling sudo mv haskell ~/../../bin

Then you can run Haskell files by calling:
haskell myHaskellFile.hs
