How to change Case of a string(BASH Scripting)?


Is there any inbuilt functionality in Unix shell script so that i can able to convert lower case string input to an upper case?

I dont want to use high level languages like java,python or perl for doing the job.

Try this:

Code:
$ echo 'my string' | tr 'a-z' 'A-Z'
MY STRING

I believe you can try "cat <name of file> | tr 'a-z' 'A-Z'" (without the < > or " ") to go from lower case to uppercase. Consequently "cat <name of file> | tr 'A-Z' 'a-z'" would take you from upper case to lower case.

cat myfile | tr 'a-z' 'A-Z'

Ok, simply put you could do this:

export lower=somevalue
export lower=`echo $lower | tr 'a-z' 'A-Z'`
