transferring binary from windows to hpux

Shivkumar — Sun, 29 Jan 2006 19:18:41 GMT

Dear Sirs,

When an ascii file is transferred to hpux; sometime i have seen ^M characters at the end of the line on hpux.

If binary file is transferred via ftp in bin mode from windows to hpux then do i need to take care of anything ?

Thanks,
Shiv

If your file is binary and you ftping to the Hpux in binary mode then you don't have to do anything on the hpux side as it will transfer as a binary file if you want to make sure you can type bin at the ftp prompt to make sure you are in binary mode.

Actually, my question is ascii on windows and unix are different.

is binary also different ?

If no; then how come binary files has been made platform independent ?

Hi SHiv:

THe "^M" character you see is the graphic representation of a carriage-return character.

Unix uses a newline (linefeed) character to denote the end of a line. Windows uses a linefeed plus carriage return couplet to do the same.

When you specify an ASCII mode FTP transfer, the conversion to add or delete a carriage return character occurs automatically. Binary mode transfers are transparent transfers. Octets are transfered "as is" and nothing is added nor deleted.

If you find that you have a file in the wrong mode, you can use 'dos2ux' or 'ux2dos' to strip or add the carriage return character. See the man pages for 'dox2ux' for more information.

Regards!

Hi Shiv,

DOS text files traditionally have carriage return and line feed pairs as their newline characters while Unix text files have the line feed as their newline character. So you get ^M when you transfer windows to Unix in ASCII mode.

hi shiv,

The ASCII code is a standardized computer code which corresponds every letter, number, punctuation mark, etc. to a number between 0 and 255. This is the way computers store text files: each character in the file corresponds to a byte (8 bits, 2^8 = 256 possible combinations).

The line feed (LF) has ASCII code 10, and the carriage return (CR) has ASCII code 13. When computers first proliferated, there was some debate over how the end of lines should be stored in the file. To this day, UNIX systems use only the LF, while DOS systems use CRLF.

That is, if your file looks like this:

he
llo

UNIX would store this file as: 104 - 101 - 10 - 108 - 108 - 111
while Windows would store this file as: 104 - 101 - 13 - 10 - 108 - 108 - 111.

hope this helps too!

kind regards

Hi Shiv,

The problem is caused when a binary file ( eg: shar file) is downloaded to a pc. The pc
places
pc style end of lines in the file. The ^M is a visual representation of
the line feed not needed on unix. You can fix this by doing the
following:

# dos2ux sharfile > sharfile1
# sh sharfile1
x - README [compressed]
x - install.ksh [compressed]
x - inquiry256.1m [compressed]
x - inquiry256.ksh [compressed]
x - inquiry256 [compressed]

Hope these informations will help you..

Shameer

Hi Shiv,

You asked about "If binary file is transferred via ftp in bin mode from windows to hpux then do i need to take care of anything ?"

No, "bin" mode is fine for binary files. You dont need to take care of anything except checksum value.

Problem is becuase of file format encoding. If you are getting ^M characters then file is in DOS format. To convert that use as,

# dos2ux

Use binary mode with ftp when transfer files between two different platforms.

Hi Shiv,

If you want to remove ^M from your files,

Using Perl :
Following command will change the orginal file itself so keep a backup copy .

perl -pi -e "s:^V^M::g" existing_file_name

You won't see the Control V on typing but it is needed to generate control

character ^M.

Using sed :
sed -e `s/^V^M//g` existing_file_name > new_file_name

Using vi :
Open file in vi and enter the following at : prompt in command mode .

:%s/^V^M//g

Are there different types of binaries or all binaries are same ?

Re: transferring binary from windows to hpux

Arunvijai_4 — Mon, 30 Jan 2006 01:50:10 GMT

Hi Shiv,

You asked "Are there different types of binaries or all binaries are same ?"

Binaries are executable files and it differs from Windows to HP-UX. Generally, Windows binaries will have .exe extension and in Unix, there is no concept of extension.

Hope this is clear.

My question was with respect to WebServer SSL certificate files which we consider as binary files. I was wondering the binaries which are created by compiling programs are different in what respect to the certificate files.

Shiv

Shiv,

Bin files are categorised as one and same for for FTP's.

to prevent you can either use a dos2unix.

also your ftp can do mget/mput

finally use "bin" at the ftp prompt before going for transfer.

-->>>>>>>>>>>>>>>

Yes, During the transfer of the SSL certificate file it will be trasfered with same DOS encoding. So ^M characters are existing.

Best way is to transfer with bin mode as,

ftp
ftp> bin
ftp> start other commands

FTP will not care about whether it is text or executable. It will be based on mode.

Lots of methods are there to remove ^M character.

Simply,

a) dos2ux will make it.

hi,

Your question: "Are there different types of binaries or all binaries are same ?"

Yes. Binaries are per platform in most cases. E.g. Windows binaries is not the same as HP-UX binaries is not the same as Linux binaries.

When source codes are compiled they produce binary files which are linked to libraries and other procedures that dependent on the environment/platform.

Exception Java "binaries" (bundled as jar files) that are supposed to be platform independent.

hope this helps too!

When you transfer webserver certificate from Windows to unix in ASCII mode, you will get ^M in certificate, To avoid this, you can transfer in bin mode.

ftp> bin
200 Type set to I.

Hi Shiv,

You can simply use,
# tr -d '\015' filename

# tr -d '\r' new.file
