Re: system function not handling string properly

Can you show what $link contains? It seems to work pretty well with echo, the only problem on my system is if $link is one of -n, -e, -E, or their combination (e.g.-eEn), which are interpreted as options to bash's builtin echo.

$link does not contain any such characters. If you run the script on the sample sql file I linked to, the result is "www.youtube.com/watch?v=mark"	[reply]

Try running a hexdump on the string. It seems it is UTF-16 encoded, there is a zero byte after each character. `echo` probably takes the null char as the end of string as in C. لսႽ† ᥲᥒ⚪⟊Ⴙᘓᖇ Ꮅᘓᖇ⎱ Ⴙᥲ𝇋ƙᘓᖇ	[reply] [d/l]

In this case I would be really interested in `print Dumper($link);` [download] ;)	[reply] [d/l]

Actually, since `system` is called correctly, the shell won't be invoked and it'll be the real `echo(1)` which only parses the `-n` option (AFAIK). Anyway, it's better to use something like `printf(1)` since it tends not to have surprising behaviour: `system('printf', '%s', $link);`	[reply] [d/l] [select]
