sh can't open script?

[Los Frijoles]

I am in the process of installing the Altera Quartus II Web Edition software. It comes in a gigantic 3GB shell script. However, even after giving permissions to execute and stuff I cannot get the install to run. Here is what I get:

kcuzner@kcuzner-AOA150:~/Downloads$ ll

-rwxrwxrwx 1 kcuzner kcuzner 3203561074 2011-11-22 08:44 11.1_173_quartus_free_linux.sh

sh: Can't open /home/kcuzner/Downloads/11.1_173_quartus_free_linux.sh

sh: Can't open ./11.1_173_quartus_free_linux.sh
kcuzner@kcuzner-AOA150:~/Downloads$ sh 11.1_173_quartus_free_linux.sh 
sh: Can't open 11.1_173_quartus_free_linux.sh
kcuzner@kcuzner-AOA150:~/Downloads$ ./11.1_173_quartus_free_linux.sh 
/bin/sh: Can't open ./11.1_173_quartus_free_linux.sh

Is there something I am missing here? The only thing I can think of is that my home directory is encrypted.

what does "file 11.1_173_quartus_free_linux.sh" give you? Also you can read the file with "less filename" . Post the first few lines with "head -n 20 filename". It's probably some form of archive wrapped with a few lines to extract/copy it.

Is the file marked as executable?

[satanselbow]

and just to complete the set... you might want to run it as sudo - though it may prompt you as required

to make executable (though from your orig post it is already!):

chmod 700 ./filename.sh

to run:

sudo sh ./filename.sh

Afterthought:
Given the size of the thing it may be corrupt - is there an md5 on the site to check it against?

Do you get the exact same error if you run this? :

sh nonexistingscript.sh

If so, can you share the output of:

ls -al /home/kcuzner/Downloads/11.1_173_quartus_free_linux.sh

Your ll command will list all files in the directory, if there is a control character in the filename this ls command should show the error.

It may also be that your process has a limit on the size of files it can open. Can you share the output of "ulimit -a" ? There is a file limit that may be limiting your access. If this is lower than 3 GB you could use sudo or change the limit.

Thanks for all the replies.

So, the file is executable (I chmodded 777...I know that's bad to do but I was just making sure).

Here is the result of doing the non-existant file check thing. quartus.sh is the now renamed install script, test.sh is a file containing "#!/bin/sh [newline]echo hi", and asdf is the non existant file.

Executing "head -20" on the script returns the following:

#!/bin/sh
# This script was generated using Makeself 2.1.5

if type printf > /dev/null; then
    print_cmd="printf"
elif test -x /usr/ucb/echo; then

So I guess it is an extractor.

Now, here is something weird I discovered. If I do "bash quartus.sh" I get the following:

kcuzner@kcuzner-AOA150:/tmp$ bash quartus.sh 
Creating directory 11.1_173_quartus_free_linux
Verifying archive integrity... All good.
Uncompressing Quartus II Web Edition (Free)...................................................................................................................................................................................................
./setup: 1: Syntax error: "&" unexpected

It took about 15-20 minutes to get to that point. I suspect that the error has something to do with using bash instead of dash.

I also ran md5 against it (there was a provided hash at the download site) and it matched up so the download is intact.

[mutley89]

Bash should run all sh scripts, on most non debian linux systems sh is a symlink to bash anyway.
Some info here concerning "makeself" :
http://megastep.org/makeself/
Basically it creates a tarball and a few lines to extract it and then run commands on the result. I think you should now have a directory containing the extracted contents of the tarball. Could you post the original script up to the point where the data starts (it will probably show as mostly escape sequences), and also the "setup" script (I think this will be either under /tmp or the "11.1_173_quartus_free_linux" subdirectory, assuming you haven't rebooted since then).

[Los Frijoles]

The setup file: http://pastebin.com/2anxFzwp

I have a feeling that the |& on line 19 isn't right...I've never seen an "or-and" before (or course, for all I know its just a boolean function I've never used). However, when I change it to || the error changes to "28: bad substitution".

Edit: SOLVED! Ok, so on a whim I decided to run "bash setup". It worked! So here is the problem: the scripts all did #!/bin/sh which on my computer redirects to dash. The scripts are written for bash! So, for people who browse this later the solution is to change the symbolic link /bin/sh to bash (and if you would like, change it back when done).

[mutley89]

Glad you solved it, as an aside "|&" is not a boolean operator, it is a bash specific way of redirecting stderr though a pipe. See here for a full explanation:
