[Solved] Script To Check Architecture

brando56894 · 2009-05-16 02:58:15

I want to add an if statement to one of my scripts to check the architecture of the computer but I cant seem to get the formatting of the if statement right. heres what I have so far:

arch=`uname -m`

if [[ "$arch" == 'x86_64']]
then
echo "x86_64"
else
echo "i686"
fi

Look in the kernel PKGBUILD, if I'm correct it should have such a check already.

if  [ "$arch" == "x86_64" ]

arch=`uname -m`

if [ "$arch" == "x86_64" ]
then
    echo "x86_64"
else
    echo "i686"
fi

Note only one "[" and spaces after "[" and before "]" and the consistent use of quotes.

or in one line...

[ "$arch" == "x86_64" ] && echo "x86_64" || echo "i686"

#!/bin/bash

arch=$(uname -m)

if [ "$arch" == 'x86_64' ]
then
    echo "x86_64"
else
    echo "i686"
fi

This works for me.

Couldn't you do:

echo $(uname -m)

?

I'm guessing he wants to do something more complicated than the "echo" at some stage...

You are correct. What I posted was just a simple statement test. I'm actually using it in my stage 2 installation script to select the proper pacman source files depending on whether its a 32 bit or 64 bit system.

Pretty nice This could be useful for one of my PKGBUILDs. (No, $CARCH doesn't work when in a chroot in my case )
