Let assume ls, cat and other command are under GPLv2 If somebody write bash script and use these command for coding, Do he/she has to release it under GPL.
No. Not even if he writes a C program that execve()'s ls or cat. But if he uses the source code of ls to implement a function in his code, then yes - he has to release it under GPL.
