converting file to binary issue

schneidz · 11-17-2012, 02:08 PM

the command should be:

Code:

ln -s /usr/bin/gunzip /usr/bin/uncompress

perhaps you shouldnt be logged in as root; since you dont really know what you are doing and you are bound to seriousely screw up your system.

look into using sudo instead.

Its OK as the workstation is just being used as a lab.

Anyway after running the symlink a ran the commands again but it still didn't work. see below:

Quote:

[root@localhost /]# sudo yum install compress uncompress ncompress
Loaded plugins: product-id, refresh-packagekit, security, subscription-manager
Updating certificate-based repositories.
Unable to read consumer identity
Setting up Install Process
No package compress available.
No package uncompress available.

[root@localhost /]#

you should look into what those commands are doing. ln creates links between files. since no-one knows how to install uncompress on redhat we are subsituting it with gunzip (it probably handles the same format that compress uses).

at this point download the file again (do not use ftp and do not attempt to modify or edit the file in any way) then run ./DBConfig_RHEL_SAM_10_0_R5.bin to execute it and post the command and any error or output in you next response.

if you must use ftp then be certainly sure that you enable binary mode when you transfer it. ask the author of the file if they have any sha1 or md5 checksum that you can use to verify the integrity of the downloaded file.

OK, going to download it again now...

@carltonp: we're happy to help people with their Linux-systems, but I would strongly recommend that you (besides asking here) RTFM the manpages. Read the documentation for your distribution!

Markus, duly noted.

In the meantime, I have ftp'd the file again in binary mode. When I run file I get the following:

Code:

[root@localhost finally]# ./DBConfig_RHEL_SAM_10_0_R5.bin
bash: ./DBConfig_RHEL_SAM_10_0_R5.bin: Permission denied
[root@localhost finally]#

please post the output of

Code:

ls -l DBConfig_RHEL_SAM_10_0_R5.bin
chmod 744 DBConfig_RHEL_SAM_10_0_R5.bin
ls -l DBConfig_RHEL_SAM_10_0_R5.bin
./DBConfig_RHEL_SAM_10_0_R5.bin

carltonp · 11-17-2012, 03:57 PM

The following is the output from the commands you suggested...

Quote:

[root@localhost finally]# ls -l DBConfig_RHEL_SAM_10_0_R5.bin
-rw-r--r-- 1 root root 442314520 Nov 18 15:58 DBConfig_RHEL_SAM_10_0_R5.bin
[root@localhost finally]# chmod 744 DBConfig_RHEL_SAM_10_0_R5.bin
[root@localhost finally]# ls -l DBConfig_RHEL_SAM_10_0_R5.bin
-rwxr--r-- 1 root root 442314520 Nov 18 15:58 DBConfig_RHEL_SAM_10_0_R5.bin
[root@localhost finally]# ./DBConfig_RHEL_SAM_10_0_R5.bin
bash: ./DBConfig_RHEL_SAM_10_0_R5.bin: /bin/sh^M: bad interpreter: No such file or directory

Well, that's really a problem with the the Linefeed.

you could use the following command to convert the file:

Code:

sed 's/^M$//' DBConfig_RHEL_SAM_10_0_R5.bin > newfile.bin

Afterwards make newfile.bin executable as you did above and then execute it. The problem is simply that the "^M" has to be deleted at the end of line.

Markus, thanks for helping out. How do I make newfile.bin an executable?

carltonp · 11-17-2012, 04:25 PM

Markus,

Silly question. I know how to make it an executable.

Anyway, I'm getting the following error message.

Quote:

[root@localhost finally]# ./newfile.bin
bash: ./newfile.bin: Permission denied

markush · 11-17-2012, 04:28 PM

permission denied means that it is not executable, do

Code:

chmod 744 newfile.bin

Markus

carltonp · 11-17-2012, 04:41 PM

Hi Mark

Thanks again for responding, I'm now getting the following after running the chmod:

Quote:

[root@localhost finally]# ./newfile.bin
bash: ./newfile.bin: /bin/sh^M: bad interpreter: No such file or directory

markush · 11-17-2012, 04:43 PM

What happens when you execute it as

Code:

bash newfile.bin
