$ cat testfile

ABCDEfgH

IJKLmnoPQ

abcdefgH

ijklLMNopq

A Linux administrator is tasked with converting testfile into all uppercase and writing it to a new file with the name uppercase. Which of the following commands will achieve

this task?

Atr '(A-Z}' '{a-z}' < testfile > uppercase

Becho testfile | tr '[Z-A]' '[z-a]' < testfile > uppercase

Ccat testfile | tr '{z-a)' '{Z-A}' < testfile > uppercase

Dtr '[a-z]' '[A-Z]' < testfile > uppercase

Show Suggested Answer

Suggested Answer: D

This command will use the tr tool to translate all lowercase letters in the testfile to uppercase letters and write the output to the uppercase file. The first argument '[a-z]' specifies the set of characters to be replaced, and the second argument '[A-Z]' specifies the set of characters to replace with.The '<' symbol redirects the input from the testfile, and the '>' symbol redirects the output to the uppercase file12.
