> Translate characters: run replacements based on single characters and character sets.
Replace all occurrences of a character in a file, and print the result:
tr {find_character} {replace_character} < {filename}
Replace all occurrences of a character from another command's output:
echo {text} | tr {find_character} {replace_character}
Map each character of the first set to the corresponding character of the second set:
tr '{abcd}' '{jkmn}' < {filename}
Delete all occurrences of the specified set of characters from the input:
tr -d '{input_characters}' < {filename}
Compress a series of identical characters to a single character:
tr -s '{input_characters}' < {filename}
Translate the contents of a file to upper-case:
tr "[:lower:]" "[:upper:]" < {filename}
Strip out non-printable characters from a file:
tr -cd "[:print:]" < {filename}
