Ola, gostaria de saber como faço pra instalar o quartus II, versao 9.1 no ubuntu 12.04
segundo o site da altera(www.altera.com) tem as seguintes instrucoes:

"1.Download the software you want to install, such as the Quartus II Software, Nios II EDS, and ModelSim-Altera software.

2.Ensure there is sufficient free disk space to contain copies of the uncompressed versions of these files.

3.Extract the Quartus II software for Linux workstations using the following command:
tar xvf 91_quartus_linux.tar

4.Execute the 'quartus/linux/install' script (extracted relative to the current directory).

5.Follow the same procedure for each additional software, making sure to target the same base installation directory (e.g., /usr2/altera) each time so that each tool is at the same relative location.

6.Select the appropriate options in the installation script to install the software."

bom, eu consegui fazer ate o passo 3, fiz os downloads do quartus, nios II e o modelsim, extrai todos na mesma pasta.

os arquivos que estao na pasta do quartus sao os seguintes:

adm.gz
agx.gz
aii.gz
common.gz

cusp.gz
cyc.gz
cyc3.gz
cyc4gx.gz

Mas nao consigo entender a partir do item 4:
tentei usando os comandos:
chmod +x install
./install
ele me devolve falando que esse arquivo nao existe.
depois tentei usando o comando
sh install
me aparece
install: 18 linha: unalias "nomeArquivo": nao encontrado
install: linha 109: simbolo nao esperado `else' Há um erro de sintaxe na periférica
install: linha 109: `else'
onde "nomeArquivo" estou me referindo a cada arquivo que esta na pasta
