returning from a function

Hi all,

I am very new to BASH shell programming. I need to return an integer from a function to the caller function. I did this:

Quote:
#!/bin/bash

function func {

ret=5543
echo "Return code should be 5543"
return $ret
}

func

echo $?

but it keeps giving me wrong return:

Quote:
alirezan@lxb402 /van/work/ip/alirezan/winchester $ ./t
Return code should be 5543
167
Can someone help me out here, please?

Thanks

ftp_nb_put - Stores a file on the FTP server (non-blocking)

SYNOPSIS
int ftp_nb_put (resource $ftp_stream, string $remote_file, string $local_file, int $mode, [int $startpos]) DESCRIPTION

Returns FTP_FAILED or FTP_FINISHED or FTP_MOREDATA. EXAMPLES
Example #1 ftp_nb_put(3) example <?php // Initiate the Upload $ret = ftp_nb_put($my_connection, "test.remote", "test.local", FTP_BINARY); while ($ret == FTP_MOREDATA) { // Do whatever you want echo "."; // Continue uploading... $ret = ftp_nb_continue($my_connection); } if ($ret != FTP_FINISHED) { echo "There was an error uploading the file..."; exit(1); } ?> Example #2 Resuming an upload with ftp_nb_put(3) <?php // Initiate $ret = ftp_nb_put($my_connection, "test.remote", "test.local", FTP_BINARY, ftp_size("test.remote")); // OR: $ret = ftp_nb_put($my_connection, "test.remote", "test.local", // FTP_BINARY, FTP_AUTORESUME); while ($ret == FTP_MOREDATA) { // Do whatever you want echo "."; // Continue uploading... $ret = ftp_nb_continue($my_connection); } if ($ret != FTP_FINISHED) { echo "There was an error uploading the file..."; exit(1); } ?> SEE ALSO
