Full Discussion: File read/ write operation
Operating Systems Linux File read/ write operation Post 302426396 by xs2punit on Tuesday 1st of June 2010 07:11:36 PM
Old 06-01-2010
My issue is not that my data is getting corrupted, my issue is that my data is not written and read the way I want.
My server writes to the file and client reads the file. As ajax at the client could ONLY read the file, there is no point of locking.

Well regarding "file release" thing: I mean that the data is not available while it is getting updates, so it seems that the file is being held until whole process is completed.
ie:
if i write 1,2....100 in text file , intead of the changing values 1,2,3 etc; i get
1,2,..100 at ONCE not one by one ie not at the time when it is UPDATED.

I am using Linux, you are write that Linux doesn't hold/hide the file. So, may be this is not a Linux issue. In case you have knowledge of Ajax, let me know if can discuss this further.

Thanks

hope this makes sense to you.

ecaccess-file-put

ECACCESS-FILE-PUT(1p)					User Contributed Perl Documentation				     ECACCESS-FILE-PUT(1p)

NAME

       ecaccess-file-put - Upload a File on the ECaccess File System

SYNOPSIS

       ecaccess-file-put -version|-help|-manual

       ecaccess-file-put [-debug] [-progress] [-umask mode] [-offset number] [-bufsize length] source-local-file [target-ecaccess-file]

DESCRIPTION

       Allow uploading source-local-file on the ECaccess File System. If no target-ecaccess-file is specified then the source-local-file name is
       used.

       The target-ecaccess-file is in the form [domain:][/user-id/]path. Please read the "Shell commands -> File Management" section of the
       "ecaccess" guide for more information on the ECaccess File System.

ARGUMENTS

       source-local-file
	       The name of the source Local File.

       target-ecaccess-file (optional)
	       The name of the target ECaccess File.

OPTIONS

       -progress
	       Provide a progress meter on the standard terminal, allowing to monitor the file transmission in real-time. The progress bar is
	       removed from the terminal when the transmission is done. This option is not supported and ignored on Windows platforms.

       -umask mode
	       The user file-creation mode mask (umask) is used to determine the file permission for newly created files. The default value is
	       640.

       -offset number
	       Every open file has an associated file offset, which determines where the next read operation will start. This number is set to 0
	       by default.

       -bufsize length
	       Specify the length of the buffer (in bytes) which is used to upload the file.  The larger the buffer the smaller the number of
	       http/s requests. By default a buffer of 10485760 bytes(10MB) is used.

       -version
	       Display version number and exits.

       -help   Print a brief help message and exits.

       -manual Prints the manual page and exits.

       -debug  Display the SOAP messages exchanged.

EXAMPLES

       ecaccess-file-put $HOME/bin/a.out

       Upload the local $HOME/bin/a.out File in the $HOME directory of the authenticated user. The Target File Name is a.out.

       ecaccess-file-put $HOME/bin/a.out c1a:/tmp/a2.out

       Upload the local $HOME/bin/a.out File in the tmp directory of c1a. The Target File Name is a2.out.
