Parameter not found.. pass in a uppercase
hi guys
i am trying to convert a uppercase var to a lowercase var and the result is pass in to another var. But i kept getting error from the variable that will be containing the result of the conversion of uppercase to the lowercase.

Code:
DB_SID=TEST
 
DB_SID_SM=/opt/$DB_SID | tr '[:upper:]' '[:lower:]'/TEST/somePath
 
echo $DB_SID_SM

when i echo $DB_SID_SM
i get:

TEST | r '[:upper:]' '[:lower:]

i want to get /opt/test/TEST/somePath

Code:
DB_SID=TEST
n12:/rdm/users/vbe $  DB_SID_SM=/opt/$(echo $DB_SID | tr '[:upper:]' '[:lower:]')/TEST/somepath
n12:/rdm/users/vbe $  echo $DB_SID_SM                                                          
/opt/test/TEST/somepath

Depending on your shell,
Quote:
Parameter Expansion - ${parameter,,pattern}:Case modification.
might do:
Code:
DB_SID_SM=/opt/${DB_SID,,}/TEST/somepath

Note: ${DB_SID,,} is bash 4.x only.
