nl(1) nl(1)

character is entered, the second character remains the default character (

:). No space

should appear between the

-d and the delimiter characters, however, this restriction

is not there for UNIX Standard (see standards (5)) compliant

nl. To deﬁne a

backslash as the delimiter, use two backslashes.

EXTERNAL INFLUENCES

For information about the UNIX Standard environment, see standards (5).

Environment Variables

LC_COLLATE determines the collating sequence used in evaluating regular expressions.

LC_CTYPE determines the characters matched by character class expressions in regular expressions.

LC_COLLATE or LC_CTYPE is not speciﬁed in the environment or is set to the empty string, the value

of LANG is used as a default for each unspeciﬁed or empty variable. If

LANG is not speciﬁed or is set to

the empty string, a default of "C" (see lang(5)) is used instead of

LANG.

If any internationalization variable contains an invalid setting,

nl behaves as if all internationalization

variables are set to "C". See environ (5).

International Code Set Support

Single-byte character code sets are supported.

EXAMPLES

Number

file1 starting at line number 10, using an increment of ten. The logical page delimiters are
