tr

Official Description

Translates characters.

Syntax

tr [-Acs] string1
					string2

Options

-A requests ASCII translation, with no extended character sets (might not be available on all UNIX variants).

-c requests the use of the complement of the chars in string1.

-s substitutes characters in string1 into string2.

Oddities

Specifying the -A option improves ASCII performance, but the option might not be available in all UNIX variants.

Example

$ cat funca                  # Note the {}
function funca {
print "In funca"
}
$                            # Change to ( )
$ tr '{}' '()' <funca > funcanew
$
$ cat funcanew               # Note the ( )
function funca (
print "In funca"
)
