the rest of the modifier.

safely through recursive invocations of

Modify the first occurrence of

in the variable's value, replacing it with

.Ar new_pattern .

.Ar new_string .

If a

.Ql g

is appended to the last slash of the pattern, all occurrences

in each word are replaced.

If a

.Ql 1

is appended to the last slash of the pattern, only the first word

is affected.

The

.Cm C

modifier is just like the

.Cm S

modifier except that the the old and new strings, instead of being

simple strings, are a regular expression (see

.Xr regex 3 )

and an

.Xr ed 1 Ns \-style

replacement string. Normally, the first occurrence of the pattern in

each word of the value is changed. The

.Ql 1

modifier causes the substitution to apply to at most one word; the

.Ql g

modifier causes the substitution to apply to as many instances of the

search pattern as occur in the word or words it is found in. Note that

.Ql 1

and

.Ql g

are orthogonal; the former specifies whether multiple words are

potentially affected, the latter whether multiple substitutions can

potentially occur within each affected word.

.It Cm T

Replaces each word in the variable with its last component.
