Top Forums Shell Programming and Scripting Problem wth spec chars in script Post 303002240 by jim mcnamara on Sunday 20th of August 2017 10:57:34 PM

Is the ASCII 13 \r part of the password, or is this running on windows?

If it really is part of the actual password, you may get better results by using printf, maybe like this:
Code:
var=$(printf "%s%c" "\$klucz" 13)

Then pass "$var" to the second script as the third arg. Also assuming the leading $ is part of the password. Leading $ characters are a problem for shell.
