Build A Script That Accept Arguments

[nathanpc]

Hello,
I want to build a script file(*.sh) to use with the CeGCC compiler, because to call the compiler i need to use this command:

$ arm-wince-mingw32ce-g++ -o hello.exe hello.cpp
Like in g++, but it's a so much long command for a thing that i use all times, then i want to build this script to run it like this, remember that the filename will be wince-g++:

wince-g++ -o hello.exe hello.cpp
This is what i want a script that put all this arguments and execute the CeGCC, remember that i want to use shell script.

Thanks,
Nathan Paulino Campos

Why not use tab-completion?


arm<tab>
-->
arm-wince-mingw32ce-g++

or you can create a file with a shorter name that links to it.


sudo ln -s /usr/bin/arm-wince-mingw32ce-g++ /usr/local/bin/wince-g++

EDIT: Even better, create an alias:

alias arm-wince-mingw32ce-g++ wince-g++
Add it to your .bash_rc or .bash_profile (I'm not at an Ubuntu machine right now, not sure which one it is)

Hello JordyD,
Thanks very much, i have created an alias, it's much better, but the name of the file in Ubuntu is .bashrc ok.

Ah, so both of them were wrong.:P

You're welcome

Just so you know, here's a simple script that would have accepted a command line arg:


#!/bin/sh

# Deduce the filename and the extension of the command line argument (arg $1)
#
filename=`echo $1 | cut -d '.' -f1`
ext=`echo $1 | cut -d '.' -f2`


# Determine the compiler to use
#
if [ "$ext" == "cpp" ]
then
CC="arm-wince-mingw32ce-g++"
elif [ "$ext" == "c" ]
then
CC="arm-wince-mingw32ce-gcc"
else
echo "Error: Unknown file type given."
exit 1
fi


# Build the application
#
$CC $1 -o $filename.exe

if [ $? -eq 0 ]
then
echo "Success!"
else
echo "Failure!"
fi


Usage would be something like:


wince-g++ hello.cpp

The result, if the compilation and build is successful would be a hello.exe file.

What you really should do though, in lieu of creating scripts and/or aliases, is to create a Makefile.
