The double quotes prevent wildcard expansion, but not in the assignment (var=pattern* is the same as var="pattern*"),
but they do make a difference when used with the echo statement. To get the wildcard * to match, they should be left out:
However, if there are multiple matches then you would get this:
Hello Everybody,
Does anyone know what the @ symbol means in a csh script, if used with a variable assignment as below
@ line = 1
why not just use....
set line=1
Many thanks

I noticed that the assignment is not working.
Please see two samples below:
Command 1:
#>ksh "i=2;echo I is $i"
Output:
#>I is
Command 2:
#>ksh <<EOF
> i=2

curlopt_wildcardmatch
CURLOPT_WILDCARDMATCH(3) curl_easy_setopt options CURLOPT_WILDCARDMATCH(3)NAME
CURLOPT_WILDCARDMATCH - enable directory wildcard transfers
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_WILDCARDMATCH, long onoff);
DESCRIPTION
Set onoff to 1 if you want to transfer multiple files according to a file name pattern. The pattern can be specified as part of the CUR-
LOPT_URL(3) option, using an fnmatch-like pattern (Shell Pattern Matching) in the last part of URL (file name).
By default, libcurl uses its internal wildcard matching implementation. You can provide your own matching function by the CUR-
LOPT_FNMATCH_FUNCTION(3) option.
A brief introduction of its syntax follows:
* - ASTERISK
ftp://example.com/some/path/*.txt (for all txt's from the root directory)
? - QUESTION MARK
Question mark matches any (exactly one) character.
ftp://example.com/some/path/photo?.jpeg
[ - BRACKET EXPRESSION
The left bracket opens a bracket expression. The question mark and asterisk have no special meaning in a bracket expression.
Each bracket expression ends by the right bracket and matches exactly one character. Some examples follow:
[a-zA-Z0-9] or [f-gF-G] - character interval
[abc] - character enumeration
[^abc] or [!abc] - negation
[[:name:]] class expression. Supported classes are alnum,lower, space, alpha, digit, print, upper, blank, graph, xdigit.
[][-!^] - special case - matches only '-', ']', '[', '!' or '^'. These characters have no special purpose.
[[]\] - escape syntax. Matches '[', ']' or ''.
Using the rules above, a file name pattern can be constructed:
ftp://example.com/some/path/[a-z[:upper:]\].jpeg
PROTOCOLS
This feature is only supported for FTP download.
EXAMPLE
See https://curl.haxx.se/libcurl/c/ftp-wildcard.html
AVAILABILITY
Added in 7.21.0
RETURN VALUE
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
