For example , we have a variable "check" as follows: $ check="Unix Shell Script" If you want to convert it into lowercase , it can be done as follows: $ check=`echo $check | tr [:upper:] [:lower:]` $ echo $check unix shell script Or if you want to convert it into uppercase , it can be done as follows: $ check=`echo $check | tr [:lower:] [:upper:]` [email protected]:~$ echo $check UNIX SHELL SCRIPT
