string1=$i

echo $string2 --> returns 'Some text'

I am trying to turn this into an alias with no luck. I would then like to put the alias into my bashrc file. I know awk is very picky about quotes. I have tried every version of quotes, single quotes, double quotes, and backslashes that I can think of.

Heyas
I'm trying to give some information on used variables.
While the first two work fine, the ones starting with a glob (is that the proper term?) fail.

Same with @ or have them escaped.

ftp_nb_get
FTP_NB_GET(3) 1 FTP_NB_GET(3)ftp_nb_get - Retrieves a file from the FTP server and writes it to a local file (non-blocking)SYNOPSIS
int ftp_nb_get (resource $ftp_stream, string $local_file, string $remote_file, int $mode, [int $resumepos])
DESCRIPTION ftp_nb_get(3) retrieves a remote file from the FTP server, and saves it into a local file.
The difference between this function and ftp_get(3) is that this function retrieves the file asynchronously, so your program can perform
other operations while the file is being downloaded.
PARAMETERS
o $ftp_stream
- The link identifier of the FTP connection.
o $local_file
- The local file path (will be overwritten if the file already exists).
o $remote_file
- The remote file path.
o $mode
- The transfer mode. Must be either FTP_ASCII or FTP_BINARY.
o $resumepos
-The position in the remote file to start downloading from.
RETURN VALUES
Returns FTP_FAILED or FTP_FINISHED or FTP_MOREDATA.
EXAMPLES
Example #1
ftp_nb_get(3) example
<?php
// Initate the download
$ret = ftp_nb_get($my_connection, "test", "README", FTP_BINARY);
while ($ret == FTP_MOREDATA) {
// Do whatever you want
echo ".";
// Continue downloading...
$ret = ftp_nb_continue($my_connection);
}
if ($ret != FTP_FINISHED) {
echo "There was an error downloading the file...";
exit(1);
}
?>
Example #2
Resuming a download with ftp_nb_get(3)
<?php
// Initate
$ret = ftp_nb_get($my_connection, "test", "README", FTP_BINARY,
filesize("test"));
// OR: $ret = ftp_nb_get($my_connection, "test", "README",
// FTP_BINARY, FTP_AUTORESUME);
while ($ret == FTP_MOREDATA) {
// Do whatever you want
echo ".";
// Continue downloading...
$ret = ftp_nb_continue($my_connection);
}
if ($ret != FTP_FINISHED) {
echo "There was an error downloading the file...";
exit(1);
}
?>
Example #3
Resuming a download at position 100 to a new file with ftp_nb_get(3)
<?php
// Disable Autoseek
ftp_set_option($my_connection, FTP_AUTOSEEK, false);
// Initiate
$ret = ftp_nb_get($my_connection, "newfile", "README", FTP_BINARY, 100);
while ($ret == FTP_MOREDATA) {
/* ... */
// Continue downloading...
$ret = ftp_nb_continue($my_connection);
}
?>
In the example above, newfile is 100 bytes smaller than README on the FTP server because we started reading at offset 100. If we didn't
disable FTP_AUTOSEEK, the first 100 bytes of newfile would be '
