Top Forums Shell Programming and Scripting how can I delete lines without actually going into the file Post 17654 by LivinFree on Tuesday 19th of March 2002 04:12:33 AM

No, it's very much line oriented. I very very very rarely use it, and for that reason don't know too much about it. The man page on my system if fairly helpful though. You might also see if you've got "ex" installed - I believe it's a little more friendly / powerful.

DH_INSTALLMAN(1)						     Debhelper							  DH_INSTALLMAN(1)

NAME
dh_installman - install man pages into package build directories SYNOPSIS
dh_installman [debhelperoptions] [manpage...] DESCRIPTION
dh_installman is a debhelper program that handles installing man pages into the correct locations in package build directories. In compat 10 and earlier, this program was primarily for when upstream's build system does not properly install them as a part of its install step (or it does not have an install step). In compat 11 and later, it supports the same features of dh_install(1) and has the advantage that it respects the nodoc build profile (unlike dh_install(1)). Even if you prefer to use dh_install(1) for installing the manpages, dh_installman can still be useful for converting the manpage encoding to UTF-8 and for converting .so links (as described below). However, that part happens automatically without any explicit configuration. You tell dh_installman what man pages go in your packages, and it figures out where to install them based on the section field in their .TH or .Dt line. If you have a properly formatted .TH or .Dt line, your man page will be installed into the right directory, with the right name (this includes proper handling of pages with a subsection, like 3perl, which are placed in man3, and given an extension of .3perl). If your .TH or .Dt line is incorrect or missing, the program may guess wrong based on the file extension. It also supports translated man pages, by looking for extensions like .ll.8 and .ll_LL.8, or by use of the --language switch. If dh_installman seems to install a man page into the wrong section or with the wrong extension, this is because the man page has the wrong section listed in its .TH or .Dt line. Edit the man page and correct the section, and dh_installman will follow suit. See man(7) for details about the .TH section, and mdoc(7) for the .Dt section. If dh_installman seems to install a man page into a directory like /usr/share/man/pl/man1/, that is because your program has a name like foo.pl, and dh_installman assumes that means it is translated into Polish. Use --language=C to avoid this. After the man page installation step, dh_installman will check to see if any of the man pages in the temporary directories of any of the packages it is acting on contain .so links. If so, it changes them to symlinks. Also, dh_installman will use man to guess the character encoding of each manual page and convert it to UTF-8. If the guesswork fails for some reason, you can override it using an encoding declaration. See manconv(1) for details. From debhelper compatibility level 11 on, dh_install will fall back to looking in debian/tmp for files, if it does not find them in the current directory (or wherever you've told it to look using --sourcedir). FILES
debian/package.manpages Lists man pages to be installed. OPTIONS
-A, --all Install all files specified by command line parameters in ALL packages acted on. --language=ll Use this to specify that the man pages being acted on are written in the specified language. --sourcedir=dir Look in the specified directory for files to be installed. This option requires compat 11 or later (it is silently ignored in compat 10 or earlier). Note that this is not the same as the --sourcedirectory option used by the dh_auto_* commands. You rarely need to use this option, since dh_installman automatically looks for files in debian/tmp in debhelper compatibility level 11 and above. manpage ... Install these man pages into the first package acted on. (Or in all packages if -A is specified). EXAMPLES
An example debian/manpages file could look like this: doc/man/foo.1 # Translations doc/man/foo.da.1 doc/man/foo.de.1 doc/man/foo.fr.1 # NB: The following line is considered a polish translation # of "foo.1" (and not a manpage written in perl called "foo.pl") doc/man/foo.pl.1 # ... NOTES
An older version of this program, dh_installmanpages(1), is still used by some packages, and so is still included in debhelper. It is, however, deprecated, due to its counterintuitive and inconsistent interface. Use this program instead. SEE ALSO
debhelper(7) This program is a part of debhelper. AUTHOR
