Der man Befehl bringt ein nettes Handbuch für viele Programme, aber wie kann ich es effektiver verwenden? Zum Beispiel man gcc bringt:
NAME
gcc - GNU project C and C++ compiler
SYNOPSIS
gcc [-c|-S|-E] [-std=standard]
[-g] [-pg] [-Olevel]
[-Wwarn...] [-Wpedantic]
[-Idir...] [-Ldir...]
[-Dmacro[=defn]...] [-Umacro]
[-foption...] [-mmachine-option...]
[-o outfile] [@file] infile...
Only the most useful options are listed here; see below for the
remainder. g++ accepts mostly the same options as gcc.
....
many text
Aber was ist, wenn ich nur einen Teil davon benötige? Was ist der beste Weg, um zu dem Abschnitt zu springen, in dem -Idir beschrieben wird, zum Beispiel?
Akzeptierte Antwort:
Suche den man Seite durch Drücken von / und die Suchzeichenfolge
man verwendet den Viewer less standardmäßig. Sie können in less suchen durch Drücken von / (Schrägstrich) und fügen Sie dann die Suchzeichenfolge hinzu, in Ihrem Beispiel -Idir

NAME
gcc - GNU project C and C++ compiler
SYNOPSIS
gcc [-c|-S|-E] [-std=standard]
[-g] [-pg] [-Olevel]
[-Wwarn...] [-Wpedantic]
[-Idir...] [-Ldir...]
[-Dmacro[=defn]...] [-Umacro]
[-foption...] [-mmachine-option...]
[-o outfile] [@file] infile...
Only the most useful options are listed here; see below for the
remainder. g++ accepts mostly the same options as gcc.
DESCRIPTION
When you invoke GCC, it normally does preprocessing, compilation,
assembly and linking. The "overall options" allow you to stop this
process at an intermediate stage. For example, the -c option says not
to run the linker. Then the output consists of object files output by
the assembler.
/-Idir
Drücken Sie die Enter Schlüssel, und erhalten Sie die erste Übereinstimmung.
Drücken Sie / (Schrägstrich) und die Enter erneut drücken, wiederholen, bis Sie den gewünschten Abschnitt gefunden haben. Sie können auch n drücken für das nächste Spiel.
-Idir
Add the directory dir to the head of the list of directories to be
searched for header files. This can be used to override a system
header file, substituting your own version, since these directories
are searched before the system header file directories. However,
you should not use this option to add directories that contain
vendor-supplied system header files (use -isystem for that). If
you use more than one -I option, the directories are scanned in
left-to-right order; the standard system directories come after.
If a standard system include directory, or a directory specified
with -isystem, is also specified with -I, the -I option is ignored.
The directory is still searched but as a system directory at its
normal position in the system include chain. This is to ensure
that GCC's procedure to fix buggy system headers and the ordering
for the "include_next" directive are not inadvertently changed. If
you really need to change the search order for system directories,
use the -nostdinc and/or -isystem options.
-iplugindir=dir
Set the directory to search for plugins that are passed by
-fplugin=name instead of -fplugin=path/name.so. This option is not
meant to be used by the user, but only passed by the driver.
Manual page gcc(1) line 10179 (press h for help or q to quit)
Drücken von h gibt einen schönen Überblick über die verfügbaren Befehle.
SUMMARY OF LESS COMMANDS
Commands marked with * may be preceded by a number, N.
Notes in parentheses indicate the behavior if N is given.
A key preceded by a caret indicates the Ctrl key; thus ^K is ctrl-K.
h H Display this help.
q :q Q :Q ZZ Exit.
---------------------------------------------------------------------------
MOVING
e ^E j ^N CR * Forward one line (or N lines).
y ^Y k ^K ^P * Backward one line (or N lines).
f ^F ^V SPACE * Forward one window (or N lines).
b ^B ESC-v * Backward one window (or N lines).
z * Forward one window (and set window to N).
w * Backward one window (and set window to N).
ESC-SPACE * Forward one window, but don't stop at end-of-file.
d ^D * Forward one half-window (and set half-window to N).
u ^U * Backward one half-window (and set half-window to N).
ESC-) RightArrow * Left one half screen width (or N positions).
ESC-( LeftArrow * Right one half screen width (or N positions).
F Forward forever; like "tail -f".
ESC-F Like F but stop when search pattern is found.
r ^R ^L Repaint screen.
R Repaint screen, discarding buffered input.
---------------------------------------------------
Default "window" is the screen height.
Default "half-window" is half of the screen height.
---------------------------------------------------------------------------
SEARCHING
/pattern * Search forward for (N-th) matching line.
?pattern * Search backward for (N-th) matching line.
n * Repeat previous search (for N-th occurrence).
N * Repeat previous search in reverse direction.
ESC-n * Repeat previous search, spanning files.
ESC-N * Repeat previous search, reverse dir. & spanning files.
ESC-u Undo (toggle) search highlighting.
&pattern * Display only matching lines
---------------------------------------------------
A search pattern may be preceded by one or more of:
^N or ! Search for NON-matching lines.
^E or * Search multiple files (pass thru END OF FILE).
^F or @ Start search at FIRST file (for /) or last file (for ?).
^K Highlight matches, but don't move (KEEP position).
^R Don't use REGULAR EXPRESSIONS.
