The substitution operator s has the form:
|
| 2 |
$line =~ s/regex1/regex2/ ;
|
| 3 |
As with m, the operator s can use any delimiter and so
|
| 4 |
$line =~ s#regex1#regex2# ;
|
| 5 |
is an equivalent form
|
| 6 |
In the substitution s/regex1/regex2/g the /g causes substitution to occur at all possible places in string (normally only the first match is found)
|
| 7 |
Note that /i and /g can be used together
