Definition and Usage
This safer version of chop removes any trailing string that corresponds to the current value of $/ (also known as $INPUT_RECORD_SEPARATOR in the English module). It returns the total number of characters removed from all its arguments. By default $/ is set to new line character.
Return Value
Example
#!/usr/bin/perl
$string1 = "This is test";
$retval = chomp( $string1 );
print " Choped String is : $string1\n";
print " Number of characters removed : $retval\n";
$string1 = "This is test\n";
$retval = chomp( $string1 );
print " Choped String is : $string1\n";
print " Number of characters removed : $retval\n";
|
This will produce following result
Choped String is : This is test
Number of characters removed : 0
Choped String is : This is test
Number of characters removed : 1
