Good morning,
I need compare this string.
if [ "$tabla" != "KKKKKK" ] || [ "$tabla" != "HHHHHH" ] || [ "$tabla" != "MMMMMM" ]; then
But this line not work, somebody can say me what is the error.
Thank you for advanced.
if [ ("$tabla" != "KKKKKK") || ( "$tabla" != "HHHHHH" ) || ( "$tabla" != "MMMMMM") ]; then
I am executing this line and do not work.
if [ ( "$tabla" != "KKKKKK" ) || ( "$tabla" != "HHHHHH" ) || ( "$tabla" != "MMMMMM" ) ]; then
[24]: 0403-057 Syntax error at line 54 : `(' is not expected.
Thank for you help.
Sorry my bad was asleep when i typed that 
Between what was the issue with original IF statement?
Your if statement looks just fine. Why do you think there is an error?
Your comparison is always true, no matter what $tabla's contents be: if it's "KKKKKK", then the second term is true, else the first.
