01:25	Bad lada ka condition 2' kadeiFalse te ka statement 2 kan sa execute.
01:31	To ngin peit kawei ka nuksa.
01:33	Nga la thoh ia u code ha ka file nestedifelse.sh.
01:38	Ngan plié ia ka.
01:40	To ngan batai ia u code mynta.
01:43	Kane kadei ka shebang line.
01:45	u variable NAME la assign u value anusha.
