Hi Ian, Thanks for taking time to have a look on it.   I actually tried to add backslash ( \' ) but did not worked. I also tried to add 2 quotes (/!\ not double quotes) same, it did not worked.   The only way it worked is to put the query behind double quotes : -q "my_query where col1 IN ('arg1','arg2')"   PS: As a reminder my script is on a Shell script file .sh   Thanks again Alex ...
