Hi,
When I do a man and save it into a file, I end up getting a lot of control characters. How can I remove them??
I tried this:
/1,$ s/^H//g
But I get an error saying "no previous regular expression".
Can someone help me with this.
Thanks,

asa - interpret ASA carriage control characters
SYNOPSIS
[files]
DESCRIPTION
interprets the output of FORTRAN programs that utilize ASA carriage control characters. It processes either the files whose names are
given as arguments, or the standard input if is specified or if no file names are given. The first character of each line is assumed to be
a control character. The following control characters are interpreted as indicated:
(blank) Output a single new-line character before printing.
(space) (UNIX Standard only, see standards(5)) The rest of the line will be output without change.
A <newline> shall be output, then the rest of
the input line.
Output a new-page character before printing.
Overprint previous line.
(UNIX Standard only, see
standards(5)) The <newline> of the previous line shall be replaced with one or more implementation-defined characters that
causes printing to return to column position 1, followed by the rest of the input line. If the + is the first character in
the input, it shall have the same effect as <space>.
Lines beginning with other than the above characters are treated the same as lines beginning with a blank. The first character of a line
is printed. If any such lines appear, an appropriate diagnostic is sent to standard error. This program forces the first line of each
input file to start on a new page.
(UNIX Standard only, see standards(5)) The action of the asa utility is unspecified upon encountering any character other than those listed
above as the first character in a line.
To view the output of FORTRAN programs which use ASA carriage control characters and have them appear in normal form, can be used as a fil-
ter:
The output, properly formatted and paginated, is then directed to the line printer. FORTRAN output previously sent to a file can be viewed
on a user terminal screen by using:
EXTERNAL INFLUENCES

Environment Variables
determines the interpretation of text within file as single- and/or multi-byte characters.
determines the language in which messages are displayed.
If or is not specified in the environment or is set to the empty string, the value of is used as a default for each unspecified or empty
variable. If is not specified or is set to the empty string, a default of "C" (see lang(5)) is used instead of
If any internationalization variable contains an invalid setting, behaves as if all internationalization variables are set to "C". See
environ(5).
International Code Set Support
Single- and multi-byte character code sets are supported.
